Book excerpt: The main purpose of power system reliability assessment is to quantify the reliability level of power system, then function as a guide to system planning and operation. Due to the random behavior of wind power generation and the intermittency associated with it, this type power generation is difficult to control and predict. With the increase of wind turbine capacity and wind farm scale, it is necessary to study the how the reliability will change within the generation and transmission system with largescale wind farm integration, and comprehensively evaluate the contribution of wind power. This report is going to presenting a study of the reliability of bulk power system with large scale wind farms integration by using sequential Monte-Carlo simulation. In this project, the sequential Monte-Carlo simulation method is presented to evaluate the reliability model of generation and transmission systems with wind farms, and the reliability indices of the wind power integration in power system is also calculated. MATLAB software is used in developing the required code for the project. The study is performed on IEEE-RTS79 test system along with wind farm model. Finally, by comparing the different integration schemes of wind farms, the reliability of generation and transmission systems integrated with largescale wind farms will be evaluated. The referenced papers, books and online links are the main source of data, and there are also some empirical values used in this project. Simulations and results are presented using MATLAB. The proposed calculation method uses sequential Monte-Carlo simulation to evaluate the reliability of the bulk power system with wind farm integration. Models of generation and transmission system and the wind farm along with the different connection solutions are discussed. With the available wind farm topology, this research focuses on the program in MATLAB to evaluating the system reliability and comparing with different integration solutions.

This book was released on 2015-04-11 with total page 0 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.

Available in PDF, EPUB and Kindle. Book excerpt: This book is a seque1 to Reliability Evaluation of Engineering Systems: Concepts and Techniques, written by the same authors and published by Pitman Books in January 1983. * As a sequel, this book is intended to be considered and read as the second oftwo volumes rather than as a text that stands on its own. For this reason, readers who are not familiar with basic reliability modelling and evaluation should either first read the companion volume or, at least, read the two volumes side by side. Those who are already familiar with the basic concepts and only require an extension of their knowledge into the power system problem area should be able to understand the present text with little or no reference to the earlier work. In order to assist readers, the present book refers frequently to the first volume at relevant points, citing it simply as Engineering Systems. Reliability Evaluation of Power Systems has evolved from our deep interest in education and our long-standing involvement in quantitative reliability evaluation and application of probability techniques to power system problems. It could not have been written, however, without the active involvement of many students in our respective research programs. There have been too many to mention individu ally hut most are recorded within the references at the ends of chapters.

Available in PDF, EPUB and Kindle. Book excerpt: Wind power generation, the most promising renewable energy, is increasingly attractive to power industry and the whole society and becomes more significant in the portfolio of generation systems. However, because of the unfavorable features of wind power, it affects all aspects of traditional processes of power system planning and operation. Power systems primarily planned for providing reliable and economic electric power to their customers. Therefore, it is critical to assess and understand the impacts of wind power on power system reliability. This thesis focuses on reliability assessment of power systems with wind power generation. Based on the investigation of reliability evaluation methodology and power system operations, a Monte Carlo based production cost simulation model is proposed and has been developed in the thesis. The model closely simulates actual system operation processes and takes system random behaviors into account. A simplified unit commitment method is created to fit the simulation for reliability evaluation purpose. The effects of wind forecast error is addressed in the model by applying forecasted value for day-ahead unit commitment and actual value for real-time operation. A process of Auto-Regressive Moving Average is designed to automatically perform day-ahead hourly wind generation forecasting through the whole simulation period. Methods for evaluating capacity value of wind power generation are also investigated. A realistic case study shows the proposed Monte Carlo based production cost simulation model can be used to assess reliability of power systems with wind power generation.

Book Synopsis Analytical Tools for Transmission Planning Studies for Offshore Wind Farm Integration by : Amirhossein Sajadi
Download or read book Analytical Tools for Transmission Planning Studies for Offshore Wind Farm Integration written by Amirhossein Sajadi and published by . This book was released on 2016 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The wind energy has been known for a very long time. Historians estimate its age as over 3000 years old. The first written evidence indicates that windmills are heritage and history of Persia. Electrical energy from offshore wind is a relatively new source of electrical energy in contrast with conventional hydro and fossil fuel-based generation. Over the last decade, the installed capacity of wind farms has grown significantly across the globe. Regardless of technology used in the wind farm, injecting a significant amount of power into an existing power system has a huge impact on its control, stability, and resiliency. In particular, injection of the power into the transmission system concerns transfer capability, line congestion, reactive power support and synchronism in the grid. In addition, the uncertain and variable nature of wind power introduces more complexity in frequency control, unit commitment, market operation and protection. This research has developed a comprehensive methodology to identify transmission system upgrades that are needed to accommodate offshore wind projects. It also develops a series of techniques to determine operational impacts of offshore wind generation on reliability and resiliency under the steady state and dynamic operations of large-scale power systems including:Steady State Stability related issues in the system including voltage regulation and reactive power availability in the area as well as power transfer capability of the transmission system. Small Signal Stability related issues in the system as a result of variability of the offshore wind power including frequency stability by using frequency response and voltage stability by using frequency domain analysis to identify the dominant voltage modes. Large Signal Stability related issues in the system as a result of operation of variable offshore wind power including rotor angle stability, frequency stability, voltage stability for long term and short term faults. This study used a simulation model of the US Eastern Interconnection as the test system and focused on the integration of a 1000MW offshore wind farm operating in Lake Erie into FirstEnergy/PJM service territory as a case study. The findings of this research provide recommendations on offshore wind integration scenarios, the locations of points of interconnection, wind profile modeling and simulation, and computational methods to quantify performance, along with operating changes and equipment upgrades needed to mitigate system performance issues introduced by an offshore wind project.
Book Synopsis Generation Reliability Modeling and Analysis of Wind Power Plants by : Claudine D'Annunzio
Download or read book Generation Reliability Modeling and Analysis of Wind Power Plants written by Claudine D'Annunzio and published by . This book was released on 2004 with total page 126 pages. Available in PDF, EPUB and Kindle. Book excerpt: The reliability impact of wind generation is evaluated using a set of reliability modeling and analysis tools implemented with MATLAB. As expected, the addition of wind generation increases the reliability of a power system. However, the extent to which the reliability is increase varies with the wind farm's penetration level. Using the LOLE, it is shown that as more wind generation is added to a power system the increase in reliability diminishes. Nonetheless, wind generators improved the reliability of a power system and deserve to be granted capacity credits. The ELCC method is used to calculate the capacity credit of wind generators. Capacity credits values between 16% and 32% were computed and correlate with the results of comparable studies. Capacity credit of wind farms also diminished with increasing penetration level.
Book Synopsis Reliability Modeling and Simulation of Composite Power Systems with Renewable Energy Resources and Storage by : Hag-kwen Kim
Download or read book Reliability Modeling and Simulation of Composite Power Systems with Renewable Energy Resources and Storage written by Hag-kwen Kim and published by . 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.

Available in PDF, EPUB and Kindle. Book excerpt: Power companies around the world are incorporating wind power into their electricity networks. Wind power is an intermittent source of energy and its technical and financial impacts on the transmission and distribution networks are not yet totally investigated. This thesis investigates the impact of wind power on power system reliability evaluation. The investigation includes long-term system planning and short-term operational planning on reliability evaluation taking into accounts different penetration levels of wind power. This thesis presents a Wind-Hydro Cooperation (WHC) method for reducing the effects of wind power fluctuations on system operation and maintaining similar power system reliability level at different wind penetrations. The thesis starts by gaining insights into methodologies of power system reliability evaluation. These methodologies are described and discussed in details. Then, relations between the wind speed and the wind turbine power output are explored for modelling the wind farm output. The output fluctuation of wind power affects the power system operation. The system requires additional operating reserve to maintain the original system reliability. To mitigate these effects of wind output fluctuation, the study explores the use of Pump-Hydro technology to cooperate with wind power to meet the increased operating reserve requirements. In order to verify and analyze the validity of the WHC method on reducing the effect of wind power fluctuation on power output and maintaining the system reliability, an extensive set of case studies are performed. Following this, the reliability analyses focus on three aspects: a) a small system for initial validation of the idea; b) a larger system for analysing the effects of the WHC method on long-term system planning and short-term operational planning; c) application of a real practical system. All the above tests involve investigation of wind penetration at different level starting from 10% to 40%. The period of investigation ranges from one day, one week, one month and then extending it to one full year.

Download or read book Performance Assessment and Management of Large Wind Farms Under Abnormal Grid Operating Conditions written by Waqar A Qureshi and published by . This book was released on 2013 with total page 156 pages. Available in PDF, EPUB and Kindle. Book excerpt: Increased penetration of wind generation into high voltage transmission systems necessitates the development of grid integration standards. Wind farms during normal system operation have been well assessed for impacts like forecasting, reliability, power quality, and transient stability following its large scale integration. Fault responses and protection schemes are currently not standardized and neither following consistent practices for existing wind farms which provides research opportunities. This is because different wind generation technologies exhibit diverse dynamic characteristics following grid disturbances, compared to synchronous generators. In this research, wind farms are illustrative of increasing influence of renewable on grids with several large scale deployments being integrated with transmission networks. The New Zealand (NZ) grid has been used in this thesis to develop methodology for ride-through criteria. During abnormal operations, ride-through requirement is prerequisite to handle large grid disturbance. Network characteristics and their interaction with available wind technologies also impact dynamic behaviour. One of the most important integration criteria for large wind farms are Fault Ride-through (FRT). Development of the FRT voltage envelope depends on transmission network characteristics along with considerations like contingency and existing protective relay settings. The first objective utilises the real New Zealand North Island network diagrams and data to test the proposed methodology, and summarise the results. Finally proposed actual voltage ride-through criteria for New Zealand grids (North and South Islands) are also presented with international benchmarking. To address the second objective, Type-1, Type-2 and Type-3 machines are modelled and connected to the same Point of Common Coupling (PCC). Large scale grid disturbance scenarios are created and identical faults are exposed to individual wind farm type. Fault current dynamics of wind farm type are then recorded from simulations and assessed for protection schemes like over-current, distance and differential. These responses are then compared from a protection relay operation viewpoint to assess the protection performance for the various Wind Turbine Generator (WTG) technologies. The third research objective explores an important aspect for fault level estimation that is sequence network equivalence. Realistic fault impedances can be used to estimate fault current levels without including the whole model of wind farms for the purpose of simplified analyses. It is known that dynamic fault impedance, or short-circuit impedance of convertor based wind farm cannot be directly evaluated through conventional methods without explicitly factoring internal machine control actions. The dynamic fault impedance of machine with positive sequence control is hard to standardize. A case study involving a DFIG (Doubly Fed Induction Generator) based wind farm having multiple units, is developed and utilise to record fault data in case of unsymmetrical faults. The data obtained is thereafter used to evaluate sequence impedance values for that wind farm during the fault period. Results obtained from analysis reveal that it is possible to estimate dynamic value of impedance of the WTG during fault factoring its internal control action The systematic development of FRT criteria proposed in this thesis provides a consistent pathway for any transmission utility to identify the important parameters and procedure required to assess and develop FRT. Fault current responses from WTGs, another outcome of this research, is useful for providing guidelines for relay manufacturers and transmission engineers to deal with protection performance issues. The proposed sequence network equivalent method proposed in this thesis helps to estimate dynamic fault impedance value without theoretical calculations during the fault. All three objectives delivered through this thesis revolve around understanding and exploring performance assessment for fault responses of large integrated WTGs during abnormal grid operation. In summary, this work is aimed towards the better understanding of wind farms during abnormal grid operating conditions to help establish improved protection and control strategies.
Book Synopsis A Framework for Assessing the Reliability of Wind Energy Conversion Systems by : Sebastian S. Smater
Download or read book A Framework for Assessing the Reliability of Wind Energy Conversion Systems written by Sebastian S. Smater and published by . This book was released on 2010 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: During the last decade, wind power generation has seen rapid development. According to the U.S. Department of Energy, achieving 20% wind power penetration in the U.S. by 2030 will require: (i) enhancement of the transmission infrastructure, (ii) improvement of reliability and operability of wind systems and (iii) increased U.S. manufacturing capacity of wind generation equipment. This research will concentrate on improvement of reliability and operability of wind energy conversion systems (WECSs). The increased penetration of wind energy into the grid imposes new operating conditions on power systems. This change requires development of an adequate reliability framework. This thesis proposes a framework for assessing WECS reliability in the face of external disturbances, e.g., grid faults and internal component faults. The framework is illustrated using a detailed model of type C WECS - doubly fed induction generator with corresponding deterministic and random variables in a simplified grid model. Fault parameters and performance requirements essential to reliability measurements are included in the simulation. The proposed framework allows a quantitative analysis of WECS designs; analysis of WECS control schemes, e.g., fault ride-through mechanisms; discovery of key parameters that influence overall WECS reliability; and computation of WECS reliability with respect to different grid codes/performance requirements.
