This book was released on 2013 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: This research proposes an efficient reliability modeling and simulation methodology in power systems to include photovoltaic units, wind farms and storage. Energy losses by wake effect in a wind farm are incorporated. Using the wake model, wind shade, shear effect and wind direction are also reflected. For solar modules with titled surface, more accurate hourly photovoltaic power in a specific location is calculated with the physical specifications. There exists a certain level of correlation between renewable energy and load. This work uses clustering algorithms to consider those correlated variables. Different approaches are presented and applied to the composite power system, and compared with different scenarios using reliability analysis and simulation. To verify the results, reliability indices are compared with those from original data. As the penetration of renewables increases, the reliability issues will become more important because of the intermittent and non-dispatchable nature of these sources of power. Storage can provide the ability to regulate these fluctuations. The use of storage is investigated in this research. To determine the operating states and transition times of all turbines, Monte Carlo is used for system simulation in the thesis. A conventional power system from IEEE Reliability Test Systems is used with transmission line capacity, and wind and solar data are from National Climatic Data Center and National Renewal Energy Laboratory. The results show that the proposed technique is effective and efficient in practical applications for reliability analysis.

This book was released on 2013-03-15 with total page 138 pages. Available in PDF, EPUB and Kindle. Book excerpt: The world is witnessing a rapid growth in wind and other renewable based electricity generation due to environmental concerns associated with electricity generation from the conventional sources. Wind power behaves quite differently than conventional electric power generating units due to its intermittent and diffuse nature. System planners and operators face the variability and uncertainty of wind power availability, and therefore, encounter considerable challenges in making decisions to maintain the adequacy and security of wind integrated power systems. This volume intends to bring out the original research work of researchers from academia and industry in understanding, quantifying and managing the risks associated with the uncertainty in wind variability in order to plan and operate a modern power system integrated with a significant proportion of wind power generation with an acceptable level of reliability. Accurate modeling of wind power variability and proper incorporation of the models in reliability and risk evaluation is very important for the planning and operation of electric power systems, and will play a crucial role in defining the requirement of various types of resources and services, such as storage and ancillary services in power systems.

This book was released on 2015 with total page 67 pages. Available in PDF, EPUB and Kindle. Book excerpt: Autonomous power system (APS) that exploits local renewable energy sources has potential to provide useful energy at lower costs when compared with conventional energy. Modern APS involves the control of renewable energy systems with intermittent power production; interaction with conventional energy generation; and management of energy storage and consumption. The system configuration of an APS is often complex due to the mix of energy generations and desire to optimize the utilization of the renewable energy. The fact that a large amount of data must be processed within a very short period of time makes the APS very challenging. In this work, we introduce a modeling and simulation methodology to analyze autonomous power systems. We develop a simulation platform using VisualSim software package to create simulation programs. We model an APS for hybrid electrical vehicle (HEV) with solar energy, thermoelectricity, fuel energy, and various buses. Simulation results suggest that controller area network (CAN) bus outperforms FlexRay and Bluetooth; this is because CAN bus optimizes the communication required by the vehicular system to use the renewable energy sources. The proposed modeling and simulation platform is easy, fast, and reliable to assess the components required in any autonomous power systems.

Book excerpt: Doctoral Thesis / Dissertation from the year 2020 in the subject Engineering - Power Engineering, Cairo University, language: English, abstract: This thesis presents a complete reliability, availability, and maintainability (RAM) analysis of the variable renewable energy (VRE) systems. Three operating concepts of the wind energy conversion systems (WECS) are considered based on the acceptable speed range of generators, while seven practical layouts of large-scale grid-connected systems are considered for the solar-PV systems. Elaborated RAM analysis of each system associated with each operating concept for the WECS and each layout of the solar-PV systems is presented starting from the subassemblies level to the subsystem level then the overall system. This thesis is purposed to describe the method of reliability, availability, and maintainability analysis of repairable and non-repairable systems using the exponential PDFs. It is also aimed to explore the method for improving the availability of these systems by managing the effort using availability importance measures of each subassembly. This analysis will also be utilized to studying the criticality of the subassemblies or subsystems of the system in order to continuous improvement. After doing this, this thesis also extends to look into the overall system availability. This analysis is a good tool for helping to identify the critical subsystems or subassemblies of the system that need more attention for improvement.

Download or read book System of Systems Approach for Integrated Energy Systems Modeling and Simulation written by and published by . This book was released on 2015 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Today's electricity grid is the most complex system ever built--and the future grid is likely to be even more complex because it will incorporate distributed energy resources (DERs) such as wind, solar, and various other sources of generation and energy storage. The complexity is further augmented by the possible evolution to new retail market structures that provide incentives to owners of DERs to support the grid. To understand and test new retail market structures and technologies such as DERs, demand-response equipment, and energy management systems while providing reliable electricity to all customers, an Integrated Energy System Model (IESM) is being developed at NREL. The IESM is composed of a power flow simulator (GridLAB-D), home energy management systems implemented using GAMS/Pyomo, a market layer, and hardware-in-the-loop simulation (testing appliances such as HVAC, dishwasher, etc.). The IESM is a system-of-systems (SoS) simulator wherein the constituent systems are brought together in a virtual testbed. We will describe an SoS approach for developing a distributed simulation environment. We will elaborate on the methodology and the control mechanisms used in the co-simulation illustrated by a case study.

Available in PDF, EPUB and Kindle. Book excerpt: The smart grid initiative, integrating advanced sensing technologies, intelligent control methods, and bi-directional communications into the contemporary electricity grid, offers excellent opportunities for energy efficiency improvements and better integration of distributed generation, coexisting with centralized generation units within an active network. A large share of the installed capacity for recent renewable energy sources already comprises insular electricity grids, since the latter are preferable due to their high potential for renewables. However, the increasing share of renewables in the power generation mix of insular power systems presents a significant challenge to efficient management of the insular distribution networks, mainly due to the variability and uncertainty of renewable generation. More than other electricity grids, insular electricity grids require the incorporation of sustainable resources and the maximization of the integration of local resources, as well as specific solutions to cope with the inherent characteristics of renewable generation. Insular power systems need a new generation of methodologies and tools to face the new paradigm of large-scale renewable integration. Smart and Sustainable Power Systems: Operations, Planning, and Economics of Insular Electricity Grids discusses the modeling, simulation, and optimization of insular power systems to address the effects of large-scale integration of renewables and demand-side management.

Download or read book Reliability and Stability Assessment of Renewable Energy and Energy Storage Integrated Systems written by Dilip Pandit and published by . This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The integration of renewable energy resources into power systems is increasing globally because of the inherent advantages of unlimited supply and negligible emissions. Decreasing capital costs and increasing efficiency have been the major drivers in the growing integration of renewable energy resources (RERs). With the projected increase in RER integration and the associated displacement of high-inertia conventional generators, there are concerns over their negative effects on the reliability and stability of power grids. The displacement of conventional sources by RERs must be limited to ensure frequency stability, which in turn affects the system reliability. Hence, with the growing integration of RERs, accurate reliability models are essential that consider limited integration of RERs along with the generation intermittency and variable component availability associated with RERs. The energy storage systems (ESS) and electric vehicles (EVs) have emerged as mitigation measures to the reliability and stability problems due to RER integration. Their growing integration dictates their inclusion in the reliability and frequency stability assessment problem. This research proposes analytical and Monte Carlo simulation (MCS) based reliability assessment techniques for RER integrated systems, with an emphasis on the photovoltaic (PV) and wind systems. A discrete convolution-based analytical model is proposed that incorporates a thermal power loss model to account for the varying availability of PV array components. Also, the model incorporates a PV power integration limit to account for frequency stability. Improvement in system reliability using wind power, ESS, and EVs is illustrated using MCS-based reliability models for these components. The operation strategy for ESS and EVs includes a dynamic PV integration level assessment technique where the maximum PV power penetration is determined with changing system states and included in the reliability assessment problem. In regard to ESS sizing, an analytical model for the inertia response and primary frequency reserve is proposed based on system frequency nadir, rate of change of frequency (RoCoF), and steady-state frequency with varying RER integration. A mixed-timing MCS-based ESS sizing algorithm is also proposed that incorporates frequency stability and wind power aggregation in the estimation of ESS size.

Available in PDF, EPUB and Kindle. Book excerpt: The trends in the energy generation as well as consumptions are increasing steadily all over the globe due to growing population and remarkable industrialization. Declining traditional fossil fuel energy resources combined with carbon emissions restrictions and environmental protection policies are compelling countries to reduce their fossil fuel combustions. Therefore in the power system, the focus is shifting towards utilizing renewable energy sources to accomplish increasing energy demands. However, introduction of renewable energy sources into the existing power systems is not easy; the integration of these resources brings up major technical, economic and social challenges. These challenges have led researchers to identify best suitable solutions for stable and economical operations of the grid. It is neither practical nor efficient for power engineers and researchers to analyze physical systems on the field by collecting data and examining the behaviour. Alternatively, modeling the physical systems using computational tools and simulating them for various possible conditions provide greater efficiency and economical senses. This thesis evaluates the suitability of the computational tools available for power system analysis from the point of view of their suitability and usage to user specific requirements. The thesis puts more emphasis on the modules of these tools which support renewable energy system modeling. Four software tools namely, NEPLAN, PowerWorld, PSAT and MATPOWER have been chosen to perform static, fault and dynamic analyses of IEEE power system test cases. In addition, the load flow results for wind energy systems integrated with IEEE 9-bus and IEEE 14-bus systems are presented. The simulation results of standard test systems as well as the renewable integrated systems show the compatibility among the commercial and open source software studied in this study.

Download or read book Novel Computational Methods for the Reliability Evaluation of Composite Power Systems Using Computational Intelligence and High Performance Computing Techniques written by Robert C. Green (II.) and published by . This book was released on 2012 with total page 224 pages. Available in PDF, EPUB and Kindle. Book excerpt: The probabilistic reliability evaluation of power systems is a complex and highly dimensional problem that often requires a large amount of computational resources, particularly processing power and time. The complexity of this problem is only increasing with the advent of the smart grid and its accompanying technologies, such as plug-in hybrid electric vehicles (PHEVs). Such technologies, while they add convenience, intelligence, and reduce environmental impacts, also add dynamic and stochastic loads that challenge the current reliability and security of the power grid. One method that is often used to evaluate the reliability of power systems is Monte Carlo simulation (MCS). As the complexity and dimensionality of a power system grows, MCS requires more and more resources leading to longer computational times. Multiple methods have previously been developed that aid in reducing the computational resources necessary for MCS in order to achieve a more efficient and timely convergence while continuing to accurately assess the reliability of a given system. Examples include analytical state space decomposition, population based metaheuristic algorithms (PBMs), and the use of high performance computing (HPC). In order to address these issues, this dissertation is focused on improving the performance of algorithms used to examine the level of reliability in composite power systems through the use of computational intelligence (CI) and HPC, while also investigating the impact of PHEVs on the power grid at the composite and distribution levels. Contributions include the development and exploration of 3 variations of a new, hybrid algorithm called intelligent state space pruning (ISSP) that combines PBMs with non-sequential MCS in order to intelligently decompose, or prune, a given state space and improve computational efficiency, an evaluation of the use of latin hypercube sampling and low discrepancy sequences in place of MCS, the use of serial and parallel support vector machines for state classification when evaluating power system reliability using MCS, an investigation of the impact that PHEVs will have when integrated into the power grid at the distribution level, and the development of a new model for the probabilistic evaluation of composite system reliability that includes one of the key technologies in the smart grid, PHEVs.
