Electric Power Engineering Handbook By Leonard L. Grigsby
This book presents a method of adapting the traditional probabilistic safety analysis (PSA) to the security analysis of a power system. The book proposes are liability model for a power system, where the possible failures of substation operations after grid faults are analysed and their impact on the power system dynamics and security is taken into account. The book presents the method in such a way that the reader is guided and equipped to build up a similar model. This reliability approach is suitable and applicable to real transmission grids, which can have hundreds of substations and lines.
In the reliability analysis of transmission systems, the basic phenomena and reliability problems are at the system level. The analysis of the local perspective, for example the outages of single components, is not adequate to capture the whole picture. So far, there have not been systematic methods that would combine local and system level issues in a similar way as this book presents. The method adapts the traditional probabilistic safety analysis (PSA) to the security analysis of a power system and includes the simulation of grid dynamics after grid faults and component failures in the modelling. This combination of different (traditional) tools enables a systematic security analysis where the connection of the failures ofsingle devices and the system level consequences, for example a system breakdown, is possible.
