Electric Power System Planning

The present book addresses the long- term power system planning issues for professionals as well as senior level and postgraduate students. The book is written as a self-reading book. Back-up materials are provided in appendices of the book. The readers can use the numerous examples presented in the chapters bodies and problems at the end of the chapters to make sure that the materials are adequately followed up.
Based on what "Matlab" provides as a powerful package for students and professional, in terms of both power system studies and mathematical aspects, the examples and problems are solved in Matlab files especially developed for this purpose. In fact, a power planning toolbox is developed by which the planning issues can be readily followed. This adds a unique feature to the book for in-depth understanding of the materials sometimes difficult to apprehend mathematically.
Chapter 1 provides an introduction to Power System Planning (PSP) issues. As nearly all PSP problems are modelled as optimization problems, this topic is covered in some details in Chapter 2. Moreover, PSP decision makings are based an both technical and economic considerations, so economic analysis is briefly covered in Chapter 3. Since for nearly each PSP study, the load has to be known, long-term load forecasting is presented in Chapter 4.
Single-node GEP problem is described in Chapter 5. This study is performed using WASP-IV, developed by International Atomic Energy Agency. The study ignores the grid structure. A Multi node GEP problem is discussed in Chapter 6 in which the transmission effects can, somehow be accounted for. The results of single node GEP is used as an input to this problem.
SEP problem is fully presented in Chapter 7. The basic differences between subtransmission and transmission SEP are also discussed. Chapter 8 devotes to NEP problem in which the network is planned. The results of NEP somehow fixes the network structure. Some practical considerations and improvements such as voltage upgrading and using higher voltage levels, using HVDC links, fuel supply costs, ect. are discussed in Chapter 9. As NEP study is typically based on some simplifying assumptions and Direct Current Load Flow analysis, detailed Reactive Power Planning study is finally presented in Chapter 10, to guarantee acceptable AC LF performance during normal as well as contingency conditions. This somehow, concludes the basic PSP problem.
The changing environments due to power system restructuring dictate some uncertainties on PSP issues. It is shown in Chapter 11 that how these uncertainties can be accounted for in the NEP problem.
