Available in PDF, EPUB and Kindle. Book excerpt: In the Electric Reliability Council of Texas (ERCOT) compressed air energy storage (CAES) is currently viewed as the most promising energy storage technology due to Texas having suitable geology for CAES and few locations suitable for pumped-hydro storage. CAES is a proven technology but the economics for new facilities are uncertain. This work quantified the economic prospects for CAES in ERCOT as a function of installed wind capacity, natural gas price, and CAES capital cost. Two types of models were developed and used in this work. The first type of model was a CAES dispatch optimization model, which determined the maximum operating profits a CAES facility could earn given a set of electricity and ancillary services market prices. These models were used to examine several separate research questions relating to the maximum potential for CAES and the impact of uncertainty and other real-world complications. The models determined that the maximum operating profit from 2002-2010 varied widely from year to year and averaged $120-140/kW-year, which is likely below the operating profits required to justify investing in CAES. The models also determined that current price forecasting methods are sufficient to earn approximately 95% of the operating profits achievable with perfect knowledge of all prices in the year. The second type of model was a unit commitment model of ERCOT, which determined the least-cost operation of all the generators in the generation fleet to meet given load. The unit commitment model was used to determine electricity and ancillary service market prices under different assumptions about natural gas price, installed wind capacity, and installed CAES capacity. The CAES dispatch optimization model was then used to determine the operating profits of a CAES facility under these scenarios. CAES operating profits were found to increase with increasing natural gas price and installed wind capacity and to decrease with increasing installed CAES capacity. CAES operating profits were estimated to support installed CAES capacities from zero to more than 6 GW, depending on the natural gas price, installed wind capacity, installed CAES capacity, and the CAES capital costs. The strongest determinant of the maximum CAES capacity that would be profitable is the natural gas price, followed by the CAES capital costs.

Book excerpt: Emerging integration of renewable energy has prompted a wide range of research on the use of energy storage to compensate for the added uncertainty that accompanies these resources. In the Electric Reliability Council of Texas (ERCOT), compressed air energy storage (CAES) has drawn particular attention because Texas has suitable geology and also lacks appropriate resources and locations for pumped hydroelectric storage (PHS). While there have been studies on incorporation of renewable energy, utilization of energy storage, and dispatch optimization, this is the first body of work to integrate all these subjects along with the proven ability to recreate historical dispatch and price conditions. To quantify the operational behavior, economic feasibility, and environmental impacts of CAES, this work utilized sophisticated unit commitment and dispatch (UC&D) models that determine the least-cost dispatch for meeting a set of grid and generator constraints. This work first addressed the ability of these models to recreate historical dispatch and price conditions through a calibration analysis that incorporated major model improvements such as capacity availability and sophisticated treatment of combined heat and power (CHP) plants. These additions appreciably improved the consistency of the model results when compared to historical ERCOT conditions. An initial UC&D model was used to investigate the impacts on the dispatch of a future high wind generation scenario with the potential to utilize numerous CAES facilities. For all future natural gas prices considered, the addition of CAES led to reduced use of high marginal cost generator types, increased use of base-load generator types, and average reductions in the total operating costs of 3.7 million dollars per week. Additional analyses demonstrated the importance of allowing CAES to participate in all available energy and ancillary services (AS) markets and that a reduction in future thermal capacity would increase the use of CAES. A second UC&D model, which incorporated advanced features like variable marginal heat rates, was used to analyze the influence of future wind generation variability on the dispatch and resulting environmental impacts. This analysis revealed that higher amounts of wind variability led to an increase in the daily net load ramping requirements which resulted in less use of coal and nuclear generators in favor of faster ramping units along with reductions in emissions and water use. The changes to the net load also resulted in increased volatility of the energy and AS prices between daily minimum and maximum levels. These impacts were also found to increase with compounding intensity as higher levels of wind variability were reached. Lastly, the advanced UC&D model was also used to evaluate the operational behavior and potential economic feasibility of a first entrant conventional or adiabatic CAES system. Both storage systems were found to operate in a single mode that enabled very high utilization of their capacity indicating both systems have highly desirable characteristics. The results suggest that there is a positive case for the investment in a first entrant CAES facility in the ERCOT market.

This book was released on 2019 with total page 344 pages. Available in PDF, EPUB and Kindle. Book excerpt: The rapid growth of electricity generation from variable renewable resources like wind and solar has greatly impacted wholesale energy markets and raised questions about future grid stability. With this paradigm shift, some existing coal, natural gas, and nuclear generators have encountered financial struggles, which has led to widespread retirements and tight capacity margins in some regions. Although this change could lead to reduced carbon emissions, synchronous generators provide some important reliability benefits to the grid that other technologies cannot easily replace. To assess the impact of an energy transition away from synchronous generation (e.g. fossil fuel fired power plants) and towards non-synchronous generation (e.g. wind and solar), future grid stability was investigated in the following three studies: (1) evaluating rotational inertia as a component of grid reliability with high penetrations of variable renewable energy, (2) determining the impact of non-synchronous generation on grid stability and identifying mitigation pathways, and (3) quantifying the regional economic and stability impacts of grid-scale energy storage. First, a method was developed to assess grid stability with increasing penetrations of non-synchronous renewable energy generation to determine when an electric grid might be more vulnerable to frequency contingencies, such as a generator outage. Unit commitment and dispatch modeling was used to quantify system inertia, an established proxy for grid stability. A case study of the Electric Reliability Council of Texas grid was used to illustrate the method. Results from the modeled scenarios showed that the Texas grid is resilient to major grid changes, even with relatively high penetrations (~30% of annual energy generation compared to 19% in 2018) of renewable energy. However, retiring nuclear power plants and private-use networks in the model led to unstable inertia levels in our results. When the system inertia was constrained to meet a minimum threshold in our model, multiple coal and natural gas combined-cycle plants were dispatched at part-load or at their minimum operating level to maintain stable system inertia levels. This behavior is expected to expand with higher renewable energy penetrations and could occur on other electric grids that are reliant on synchronous generators for inertia support. A method was also developed for assessing the impacts of stability support from inverter-connected resources. In this analysis, a fully disaggregated, inertia-constrained unit commitment and dispatch model was used to study the stability of future grid scenarios with high penetrations of non-synchronous renewable energy generation. As before, the Texas grid (the Electric Reliability Council of Texas – ERCOT) was used as a test case and instances when the system inertia fell below 100 GW·s (the grid's current minimum level) were found, starting at an annual renewable energy penetration (including both synchronous and non-synchronous renewable resources) of ~30% in our model. At an ~88% renewable energy penetration, the average system inertia level also fell to 100 GW·s. When the modeled critical inertia limit was reduced to 80 GW·s, no critical inertia hours occurred for renewable energy penetrations up to 93% of annual energy. The critical inertia limit could drop to 60 GW·s if the largest generators in ERCOT (two co-located nuclear plants) were retired, but this had the same effect as reducing the limit to 80 GW·s and keeping these generators online, since the nuclear plants contribute a large portion of the grid's system inertia. Emissions also increased by ~25% in the modeled scenarios where these nuclear plants were retired. If the critical inertia limit was kept the same (100 GW·s), adding 525 MW of fast frequency response from wind, solar, and energy storage could reduce the number of critical inertia hours by 86% with a response time of 15 cycles. Therefore, while the transition to a grid with mostly non-synchronous energy generation should be handled with care, many feasible pathways for integrating inverter-connected technologies and maintaining a stable grid exist. Building on the prior two methods, a third method was developed to evaluate the impact of energy storage systems on grid stability and system cost. While many grid-scale energy storage projects have been built and several have been announced, energy storage is costly and could negatively impact grid stability if systems are connected non-synchronously. Three different energy storage technologies with varying durations, ramp rates, and costs were modeled using a linearized dispatch model with discrete transmission zones and sub-hourly intervals (i.e. 15 minutes). Small penetrations of these technologies were modeled in a grid dominated by non-synchronous generation (51% wind and solar) to identify optimal storage zones. Transmission zones in the North, Northwest, West, Far West, and Panhandle regions were found to be the most favorable for building grid-scale storage from an economic standpoint. Next, higher energy storage penetrations were modeled to analyze the impact of storage on system inertia and the system cost. These high penetration scenarios focused primarily on storage divided across the optimal storage zones in proportion to their system cost impact. The modeling results showed that flywheels were able to maintain higher system inertia levels. Even so, the system cost was much lower when compressed air energy storage systems were modeled, demonstrating that high-duration energy storage technologies provided the most value to the grid. Energy storage was also more effective at maintaining grid stability and reducing costs than peaking plants. As a result, our model showed that new peakers might not be revenue sufficient in zones with high penetrations of renewable energy and energy storage. Many options exist for reliably integrating high penetrations of variable renewable energy generation, including an inertia market, synthetic and virtual inertia, and grid-scale storage, but few of these solutions are available today. Together, each of the analyses presented in this dissertation communicate when grid stability issues might occur and how low system inertia levels could be avoided

This book was released on 2020-12-17 with total page 164 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wind power and photovoltaic energy play a significant role in sustainable energy systems. However, these two renewable energy sources do not generate electrical energy on demand and are subject to natural fluctuations. Thus, the need for compensatory measures arises. Compressed air energy storage power plants (CAES) are a possible solution to providing negative and positive control energy in the electric grid. However, in contrast to other energy storage devices such as pumped hydro energy storage or batteries, the storage medium compressed air hardly contains any energy (or more precisely: enthalpy). Yet, compressed air storage allows the operation of highly efficient gas turbines, which are not only particularly fast available but also achieve better efficiency than combined cycle power plants used today, as illustrated by the example of the modern gas and steam power plant Irsching with ηtc = 60%from 2011 compared to the 20 years older McIntosh CAES with ηtc = 82.4 %. In this thesis, the calculation methods for the thermodynamics of the CAES process are presented and validated by measured data from the operations of the CAES power plant Huntorf. Both the steady state and the dynamic (time-dependent) analyses of the process take place. The characteristic value efficiency is discussed in detail, since numerous different interpretations for CAES exist in the literature. A new calculation method for the electric energy storage efficiency is presented, and a method for the calculation of an economically equivalent electricity storage efficiency is developed. Consideration is given to the transformation of the CAES process into a hydrogen-driven and, thus, greenhouse gas-free process. Finally, a model CAES system is tested in a 100 % renewable model environment. Consequently, it can be stated that in the steady-state thermodynamic calculation in particular, the consideration of realistic isentropic efficiencies of compressors and turbines is essential to correctly estimate the characteristic values of the process. Furthermore, a steadystate view should always be accompanied by dynamic considerations, since some process characteristics are always time-dependent. The simulation shows that by mapping transient operating conditions, the overall efficiency of the system must be corrected downwards. Nevertheless, in the model environment of a 100 % renewable energy system, it has been shown that a CAES is a useful addition that can provide long-term energy storage.

Available in PDF, EPUB and Kindle. Book excerpt: As agreed in the Paris Agreement, Canada is committed to combat climate change through reducing greenhouse gas (GHG) emissions and keeping the temperature rise well below 2ʻ C above pre-industrial levels. One of the ways to achieve this goal is through replacing high GHG emitting electricity sources with renewables energy, such as wind and solar energy. However, due to their intermittent nature, wind and solar must be paired with energy storage to be a reliable source of electricity. Compressed air energy storage (CAES) in salt caverns is a well-demonstrated and effective grid-scale energy storage technology that can support large-scale integration of renewables. This thesis addresses on three major aspects of implementing CAES in Canada: I) geomechanical design workflow, II) CAES siting in salt caverns across Canada: a geomechanics perspective, and III) potential of deep brine disposal in southwestern Ontario. Part I of the thesis discusses the geomechanical design workflow for CAES in salt caverns. The workflow includes tasks and design decisions that are executed from a CAES project's pre-feasibility period to end of operation period. The major sections of the workflow include geology, data collection and mechanical earth model, constitutive model: creep, geomechanical issues and cavern design decisions, and monitoring. The goal of this section is to identify and investigate high-level geological engineering tasks that should be considered when designing a salt cavern for CAES. Part II of the thesis entails a comprehensive study on the siting of CAES plants in salt caverns across Canada. The objective of the study was to develop an evaluation methodology and use it to determine suitable sites for CAES based on geology, renewable energy potential, energy demand, and existing infrastructure. Multi-criteria analysis was utilized as a tool to compare and evaluate sites. Six criteria are used in the evaluation framework: 1) depth to salt strata, 2) salt strata thickness, 3) renewable energy potential, 4) energy demand, 5) proximity to existing natural gas infrastructure, and 6) proximity to existing electrical infrastructure. The study will be useful to the government in developing energy policies, drafting regulations, and utilized by the industry in deciding the location for front-end engineering and design (FEED) studies. Part III of the thesis comprises of a study on the potential of deep brine disposal in southwestern Ontario. The aim of the study was to develop an evaluation methodology and investigate suitable sites for brine disposal in southwestern Ontario based on geological, geomechanical, and petrophysical parameters. A multi-criteria analysis evaluation system was developed based on relevant disposal parameters and applied to sites throughout southwestern Ontario. Criteria used in the study include permeability, porosity, depth, thickness, disposal formation lithology, and caprock lithology. The study will benefit industrial and academic readers to understand the parameters required for deep brine disposal and appreciate the availability of suitable locations for disposal in southwestern Ontario.

Book excerpt: The load-following capability of fluidized bed combustion-augmented compressed air energy storage systems was evaluated. The results are presented in two parts. The first part is an Executive Summary which provides a concise overview of all major elements of the study including the conclusions, and, second, a detailed technical report describing the part-load and load following capability of both the pressurized fluid bed combustor and the entire pressurized fluid bed combustor/compressed air energy storage system. The specific tasks in this investigation were to: define the steady-state, part-load operation of the CAES open-bed PFBC; estimate the steady-state, part-load performance of the PFBC/CAES system and evaluate any possible operational constraints; simulate the performance of the PFBC/CAES system during transient operation and assess the load following capability of the system; and establish a start-up procedure for the open-bed PFBC and evaluate the impact of this procedure. The conclusions are encouraging and indicate that the open-bed PFBC/CAES power plant should provide good part-load and transient performance, and should have no major equipment-related constraints, specifically, no major problems associated with the performance or design of either the open-end PFBC or the PFBC/CAES power plant in steady-state, part-load operation are envisioned. The open-bed PFBC/CAES power plant would have a load following capability which would be responsive to electric utility requirements for a peak-load power plant. The open-bed PFBC could be brought to full operating conditions within 15 min after routine shutdown, by employing a hot-start mode of operation. The PFBC/CAES system would be capable of rapid changes in output power (12% of design load per minute) over a wide output power range (25% to 100% of design output). (LCL).

Book excerpt: Energy storage technologies (such as pumped hydro, compressed air energy storage, various types of batteries, flywheels, electrochemical capacitors, etc.) provide for multiple applications that include energy management, backup power, load levelling, frequency regulation, voltage support, and grid stabilisation. Importantly, not every type of storage is suitable for every type of application, motivating the need for a portfolio strategy for energy storage technology. There are four challenges related to the widespread deployment of energy storage. The challenges are cost competitive energy storage technologies (including manufacturing and grid integration), validated reliability and safety, equitable regulatory environment, and industry acceptance. This book sets out potential options to improve energy storage. It also presents a number of specific actions that could help maintain both scientific advancements and a pipeline of project deployments.

Download or read book Extensible Modeling of Compressed Air Energy Storage Systems written by Siddharth Atul Kakodkar and published by . This book was released on 2018 with total page 84 pages. Available in PDF, EPUB and Kindle. Book excerpt: There is a growing number of renewable energy sources that can supply power to the electrical grid. These renewable sources of energy are intermittent in nature and therefore the transition from using fossil fuels to green renewables requires the use of energy storage technologies to maintain and regulate a reliable supply of electricity. Energy storage technologies play a key role in allowing energy providers to provide a steady supply of electricity by balancing the fluctuations caused by sources of renewable energy. Compressed Air Energy Storage (CAES) is a promising utility scale energy storage technology that is suitable for long-duration energy storage and can be used to integrate renewable energy (such as Wind energy) to the electrical grid. CAES technologies can be broadly classified into 3 types: Diabatic-CAES (D-CAES), Adiabatic-CAES (A-CAES) and Isothermal-CAES (I-CAES). The author first performs a review on the different types of energy storage available today and a literature review on of CAES system level models, Turbomachinery models, and cavern models. After the gaps in literature are identified, the author then develops a flexible and extensible model of an A-CAES system, which can be used a CAES plant designer to obtain a first order thermodynamic evaluation of a particular plant configuration. The developed model is scalable, modular and can be connected to a control strategy. The model is able to capture time dependent losses and part load behavior of turbomachinery. The modeling methodology is focused around keeping the model extensible, i.e. components and their fidelity can be easily altered for the model's future growth. The components modeled are the compressor, the turbine, the induction motor, the generator, and a thermal energy storage device to the make the CAES plant adiabatic. The model is created using the Matlab/Simulinkʼ software, which is commonly used tool for modeling. The A-CAES plant model was simulated for 23.3 hours comprising of 12.47 hours of charging using a mass flow rate of 107.5 kg/s, 8 hours of storage and 2.83 hours of discharge using a mass flow rate of 400 kg/s. The maximum and minimum cavern pressures were 72 bar and 42 bar respectively. The obtained round trip efficiency is 76.24%. Additionally, the turbine start-up time was found to be 760 seconds. The compressor train average efficiency was calculated as 70%, the expansion train average efficiency was calculated as 81% and the TES efficiency was calculated as 91%. The models simulated the behavior of an A-CAES plant accurately with the compressor and turbine showing a close resemblance to their performance maps. The results indicate that Adiabatic-CAES is a promising and emerging technology. However, further research and development is required beyond this thesis; specifically, in the area of thermal energy storage and management. Finally, the author makes recommendations on how to further improve upon the achieved objectives in this work.

Download or read book Behind the meter Compressed Air Energy Storage Feasibility and Applications written by Chioma Christiana Anierobi and published by . This book was released on 2019 with total page 59 pages. Available in PDF, EPUB and Kindle. Book excerpt: In many jurisdictions, commercial and industrial (C&I) customers are charged for their energy consumption as well as the power drawn from the grid at peak load hours. In Ontario, the demand-based charge component of the electricity cost has been skyrocketing, and this cost often accounts for a significant portion of the overall operating cost of large customers. The Ontario Government in 2010 launched the Industrial Conservation Initiative (ICI) program which requires large customers (Class A) to pay a Global Adjustment (GA) charge, based on their percentage contribution in load during the top five system peak load hours over a one-year base period. This offers enormous savings opportunity to many industrial customers by using strategies to reduce or offset their load during these system peak load hours. However, managing demand can be challenging when faced with production constraints in areas of high-energy sensitive production lines where short interruptions are not permitted. Energy Storage System (ESS) offers the customer the capability to carry out its usual operations while simultaneously saving on the electricity bill through demand reduction. ESS can provide electricity to the facility during system peak periods to reduce the power drawn from the grid, while during non-peak price periods, the ESS is recharged by harnessing the low-cost power. In this work, a detailed operations model of behind-the-meter Small Scale Compressed Air Energy Storage (SS-CAES) is developed for an industrial customer, with an existing well/cavern that can be re-purposed for air storage. The developed optimization model manages the operation of the CAES facility to minimize electricity costs, determining the storage energy output and the corresponding charging and discharging decisions of the SS-CAES system. Furthermore, a detailed economic analysis is carried out to examine financial viability of a practical behind-the-meter SS-CAES project. Some key parameters such as life cycle, CAES capacity and capital cost, and electricity price are considered for carrying out a sensitivity analysis, and the results suggest that SS-CAES is economically viable in the current Ontario rate structure. It is shown that the cost of an SS-CAES project and GA charges are the key determining factors for economic deployment of SS-CAES in Ontario.
