Available in PDF, EPUB and Kindle. Book excerpt: This thesis centres on issues of economic efficiency originating from the large-scale development of intermittent renewable energy sources (RES) in Europe. The flexible resources that are necessary to cope with their specificities (variability, low-predictability, site specificity) are already known, but adequate signals are required to foster efficient operation and investment in these resources. A first question is to what extent intermittent RES can remain out of the market at times when they are the main driver of investment and operation in power systems. A second question is whether the current market design is adapted to their specificities. These two questions are tackled in four distinct contributions.The first chapter is a critical literature review. This analysis introduces and confronts two (often implicit) paradigms for RES integration. It then identifies and discusses a set of evolutions required to develop a market design adapted to the large-scale development of RES, such as new definitions of the products exchanged and reorganisation of the sequence of electricity markets.In the second chapter, an analytical model is used to assess the potential of intraday markets as a flexibility provider to intermittent RES with low production predictability. This study highlights and demonstrates how the potential of intraday markets is heavily dependent on the evolution of the forecast errors.The third chapter focuses on the benefits of curtailing the production by intermittent RES, as a tool to smooth out their variability and reduce overall generation costs. Another analytical model is employed to anatomize the relationship between these benefits and a set of pivotal parameters. Special attention is also paid to the allocation of these benefits between the different stakeholders.In the fourth chapter, a numerical simulation is used to evaluate the ability of the European transmission system operators to tackle the investment wave required in order to manage the production of intermittent RES. Alternative financing strategies are then assessed. The findings reveal that under the current trend of tariffs, the volumes of investment forecasted will be highly challenging for transmission system operators.

Available in PDF, EPUB and Kindle. Book excerpt: This dissertation explores the impact of intermittent renewable integration in electricity market design. U.S. electricity markets adopt a two-settlement structure with day-ahead and real-time markets. Wind power integration poses a challenge for this market structure because day-ahead wind production forecasts are uncertain and significant rescheduling costs may occur in real time, increasing the need for out-of-market uplift payments. Chapters 2 and 3 investigate whether a multi-settlement structure, where participants can re-trade their forward positions in multiple intraday stages between the day-ahead and real-time markets, reduces uplift payments and system costs, relative to a two-settlement structure. Chapter 2 implements unit commitment and dispatch models that account for intertemporal constraints and are solved on a 36-node test system using historical wind forecasts provided by a Regional Transmission Organization (RTO), as well as synthetic wind forecasts reproducing the observed correlation in the historical data. The performance of market designs are compared across varying levels of wind penetration, where it is found that transitioning from the current two-settlement design to the proposed multi-settlement design may not improve efficiency in power system operations, and RTOs should not use their own forecasts to represent wind power generation for unit commitment and dispatch decisions. Chapter 3 develops laboratory experiments for the two-settlement and multi-settlement structures, where participants play the role of electricity generating companies who sell electricity into the market through a uniform price auction. Unit commitment and dispatch models are used to clear the market and compare the performance of both market designs under varying levels of wind penetration. Results show there is no significant difference in the performance of each market design due to participants not following their wind forecast signals. Chapter 4 examines resource adequacy and revenue sufficiency under two market designs and increasing levels of wind penetration. A capacity market structure provides an incentive for electricity suppliers to invest in new capacity through payments determined in a centralized capacity auction, while an energy-only market structure provides an incentive for electricity suppliers to invest in new capacity through high energy price caps and an operating reserve demand curve (ORDC) price adder mechanism. Equilibrium and mixed integer models are formulated to compare market performance under natural gas price, wind forecast, and demand uncertainty. Results from both market structures are evaluated on a test system comprised of seven nodes, six generators, and ten transmission lines, and show that only modern natural gas generating technologies have incentive to invest in new capacity.

Download or read book Integrating Variable Renewable Energy in Electricity Markets written by Sophia B. Taylor and published by Nova Science Publishers. This book was released on 2013 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many countries, reflecting very different geographies, markets, and power systems, are successfully managing high levels of variable renewable energy on the electric grid, including that from wind and solar energy. This book documents the diverse approaches to effective integration of variable renewable energy among six countries: Australia (South Australia), Denmark, Germany, Ireland, Spain, and the United States (Colorado and Texas), and summarises policy best practices that energy ministers and other stakeholders can pursue to ensure that electricity markets and power systems can effectively co-evolve with increasing penetrations of variable renewable energy. There is no one-size fits all approach; each country has crafted its own combination of policies, market designs, and system operations to achieve the system reliability and flexibility needed to successfully integrate renewables. Notwithstanding this diversity, the approaches all coalesce around five strategic areas: lead public engagement, particularly for new transmission; co-ordinate and integrate planning; develop rules for market evolution that enable system flexibility; expand access to diverse resources and geographic footprint of operations; and improve system operations. This book also underscores the value of countries sharing their experiences. The more diverse and robust the experience base from which a country can draw, the more likely that it will be able to implement an appropriate, optimised, and system-wide approach.

Available in PDF, EPUB and Kindle. Book excerpt: This thesis explores three topics that are central to a low-carbon development path for India, namely, the Indian natural gas market, grid integration of renewable energy, and energy efficiency programs. In the first part of the thesis, the effect of price liberalization on the natural gas market is analyzed by developing a mixed complementarity model. Gas prices in the liberalized market are found to be significantly higher than the government regulated prices under the status quo. However, the liberalized market is found to overcome the prevailing gas shortages in the country and improve total welfare. Irrespective of the gas pricing policy, imported liquefied natural gas is found to be a significant part of the supply mix in the future. Inadequate investments in gas pipelines can lead to network congestion and price spikes. Gas pipeline infrastructure would, therefore, be the key to developing an efficient gas market. Finally, the present formula for sharing profits of domestic gas producers with the government is found to incentivize inefficient investments in gas exploration and production. The second part of the thesis tests the feasibility of integrating large scale renewable energy projects into the electricity grid using the state of Delhi as a case study. Wind resources from the state of Tamilnadu were found to have a very high seasonal and diurnal correlation with electricity demand in Delhi. Solar energy from the state of Rajasthan is found to have a complementary seasonal profile to that of wind power from Tamilnadu. Simulation of the optimal grid dispatch shows that integration of wind and solar power is feasible at modest incremental costs. However, regional coordination for planning transmission investments is a must. The third part of the thesis analyzes the effect on utility finances and consumer tariffs of implementing utility-funded demand-side energy efficiency (EE) programs using the state of Delhi as a case study. The impacts are examined by developing scenarios for (a) incentive mechanisms for mitigating the financial risk of utilities, (b) the share of utility funding in total program costs, (c) the sale of conserved electricity into the spot market and (d) the level of power shortages utilities are facing. Although the average consumer tariff would increase only modestly, consumers participating in EE programs would benefit from a reduction in their electricity consumption. While utility incentive mechanisms can mitigate the utilities' risk of losing long-run returns, they cannot address the risk of a consistently negative cash flow. In case of power shortages, the cash flow risk is significantly amplified. It is found to be very sensitive to marginal tariffs of consumers facing power shortages.

This book was released on 2020-12-02 with total page 228 pages. Available in PDF, EPUB and Kindle. Book excerpt: The electric power sector is poised for transformative changes. Improvements in the cost and performance of a range of distributed energy generation (DG) technologies and the potential for breakthroughs in distributed energy storage (DS) are creating new options for onsite power generation and storage, driving increasing adoption and impacting utility distribution system operations. In addition, changing uses and use patterns for electricity—from plug-in electric vehicles (EVs) to demand response (DR)—are altering demands placed on the electric power system. Finally, the infusion of new information and communications technology (ICT) into the electric system and its markets is enabling the collection of immense volumes of data on power sector operations and use; unprecedented control of generation, networks, and loads; and new opportunities for the delivery of energy services. In this Special Issue of Energies, research papers on topics related to the integration of distributed energy resources (DG, DS, EV, and DR) are included. From technologies to software tools to system-wide evaluations, the impacts of all aforementioned distributed resources on both operation and planning are examined.

Available in PDF, EPUB and Kindle. Book excerpt: Reducing the Greenhouse Gas pollution and promoting energy efficiency among consumers' energy use have been major public policy issues recently. Currently, both the United States and the European Union have set up explicit percentage requirements that require energy generators or consumers to undertake a certain percentage of their energy production or consumption from renewable sources. To achieve their renewable targets, the Tradable Green Certificates (TGC) system has been introduced in their electricity markets. Moreover, in order to promote energy conservation and achieve energy efficiency targets, price policies and price changes derived from environmental regulations have played a more important role in reducing electricity consumption. My research studies problems associated with these policy implementations. In Chapter 1, I analyze a competitive electricity market with two countries operated under a common TGC system. By using geometric illustrations, I compare the two countries' welfare when the renewable quota is chosen optimally under the common certificate market with three different situations. The policy recommendation is that when the value of damage parameter is sufficiently small, full integration with a TGC market is welfare superior to full integration of an all fossil-fuel based market with an optimal emissions standard. In Chapter 2, by analyzing a stylized theoretical model and numerical examples, I investigate the performance of the optimal renewables policy under full separation and full integration scenarios for two countries' electricity markets operated under TGC systems. In my third chapter, I look at residential electricity consumption responsiveness to increases of electricity price in the U.S. and the different effect of a price increase on electricity use for states of different income levels. My analysis reveals that raising the energy price in the short run will not give consumers much incentive to adjust their appliances and make energy conservation investments to reduce electricity use, while in the long run, consumers are more likely to lower their electricity consumption, facing the higher electricity price induced from regulation policies. In addition, for states of higher per capita GDP, raising the electricity price may be more effective to ensure a cut in electricity consumption.
