Book Synopsis Unit Commitment in Electric Energy Systems by : Miguel F. Anjos
Download or read book Unit Commitment in Electric Energy Systems written by Miguel F. Anjos and published by Foundations and Trends in Electric Energy Systems. This book was released on 2017-12-18 with total page 112 pages. Available in PDF, EPUB and Kindle. Book excerpt: The unit commitment problem is a fundamental problem in the electric power industry. It addresses a fundamental decision that is taken when operating a power system, namely to set the schedule of power production for each generating unit in the system so that the demand for electricity is met at minimum cost. The schedule must also ensure that each unit operates within its technical limits; these typically include ramping constraints and minimum uptime/downtime constraints. Units that are scheduled to produce electricity during a given time period are said to be committed for that period. Unit Commitment in Electric Energy Systems presents the most relevant mathematical optimization models for the unit commitment problem. It is an ideal starting reference for practitioner and researchers interested in this important and challenging problem, as it introduces the key technical details and summarizing their significance.

Download or read book Electrical Power Unit Commitment written by Yuping Huang and published by Springer. This book was released on 2017-01-13 with total page 93 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume in the SpringerBriefs in Energy series offers a systematic review of unit commitment (UC) problems in electrical power generation. It updates texts written in the late 1990s and early 2000s by including the fundamentals of both UC and state-of-the-art modeling as well as solution algorithms and highlighting stochastic models and mixed-integer programming techniques. The UC problems are mostly formulated as mixed-integer linear programs, although there are many variants. A number of algorithms have been developed for, or applied to, UC problems, including dynamic programming, Lagrangian relaxation, general mixed-integer programming algorithms, and Benders decomposition. In addition the book discusses the recent trends in solving UC problems, especially stochastic programming models, and advanced techniques to handle large numbers of integer- decision variables due to scenario propagation

Available in PDF, EPUB and Kindle. Book excerpt: Power system operation is one of the important issues in the power industry. The book aims to provide readers with the methods and algorithms to save the total cost in electricity generation and transmission. It begins with traditional power systems and builds into the fundamentals of power system operation, economic dispatch (ED), optimal power flow (OPF), and unit commitment (UC). The book covers electricity pricing mechanisms, such as nodal pricing and zonal pricing, based on Security-Constrained ED (SCED) or SCUC. The operation of energy market and ancillary service market are also explored. "It covers a wide range of interesting topics, which could be very useful for understanding the main phenomena ruling power systems economy (such as Optimal Power Flow analysis and unit Commitments). It addresses topics widely treated in the literature, hence it is important to outline its distinctive features compared to other similar books. The book is well structured and well balanced." —Alfredo Vaccaro, University of Sannio, Italy
Book Synopsis The Next Generation of Electric Power Unit Commitment Models by : Benjamin F. Hobbs
Download or read book The Next Generation of Electric Power Unit Commitment Models written by Benjamin F. Hobbs and published by Springer Science & Business Media. This book was released on 2006-04-11 with total page 320 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the years, the electric power industry has been using optimization methods to help them solve the unit commitment problem. The result has been savings of tens and perhaps hundreds of millions of dollars in fuel costs. Things are changing, however. Optimization technology is improving, and the industry is undergoing radical restructuring. Consequently, the role of commitment models is changing, and the value of the improved solutions that better algorithms might yield is increasing. The dual purpose of this book is to explore the technology and needs of the next generation of computer models for aiding unit commitment decisions. Because of the unit commitment problem's size and complexity and because of the large economic benefits that could result from its improved solution, considerable attention has been devoted to algorithm development in the book. More systematic procedures based on a variety of widely researched algorithms have been proposed and tested. These techniques have included dynamic programming, branch-and-bound mixed integer programming (MIP), linear and network programming approaches, and Benders decomposition methods, among others. Recently, metaheuristic methods have been tested, such as genetic programming and simulated annealing, along with expert systems and neural networks. Because electric markets are changing rapidly, how UC models are solved and what purposes they serve need reconsideration. Hence, the book brings together people who understand the problem and people who know what improvements in algorithms are really possible. The two-fold result in The Next Generation of Electric Power Unit Commitment Models is an assessment of industry needs and new formulations and computational approaches that promise to make unit commitment models more responsive to those needs.

Book Synopsis Unit commitment and investment valuation of flexible biogas plants in German power markets by : Hochloff, Patrick
Download or read book Unit commitment and investment valuation of flexible biogas plants in German power markets written by Hochloff, Patrick and published by kassel university press GmbH. This book was released on 2017 with total page 196 pages. Available in PDF, EPUB and Kindle. Book excerpt: Biogas plants become more flexible, scheduling their power generation with respect to market prices. For this purpose the electrical capacity of power units is extended to convert the continuously produced gas as well as the gas held in storage. This work has shown how gas plants with extended capacity located at a gas production site can be analyzed on the basis of unit commitment. Mixed integer linear programs (MILP) have been developed for the unit commitment of such plants in different use cases. The models developed consider gas plants at a gas production site participating in German power markets, switching between static and variable gas supply, providing secondary and tertiary control reserve, and claiming the German market and flexibility premium. The models can be applied to plan daily schedules for the operation of these gas plants. Furthermore, the models can be applied to analyze the benefits of extending the electrical or storage capacity of gas plants located at a gas production site. The models calculate the optimized gross income that can be applied as cash flow for determining the net present value (NPV) of investments in extended electrical and storage capacity.
