In this book, adaptive protection schemes for power systems with DG units are proposed by integrating fault diagnosis with protection relay coordination strategies. An automated fault diagnosis method is developed using three staged radial basis function neural network (RBFNN) in which the first RBFNN determines the fault distance from each source, the second RBFNN identifies the exact faulty line and the third RBFNN determines the circuit breakers that must be open or close for isolating the faulty zone. After identifying the exact faulty line, then protection relay coordination is...

In this book, harmonic source localization methods have been developed by considering two methods. The first method considers a single point measurement strategy for locating dominant harmonic source by determining the harmonic contributions of utility and customer at a single point called as the point of common coupling. This approach is based on a Norton equivalent circuit for simplifying the system under study, and modelling the customer load with parallel RLC components using the measured harmonic voltage and current at the PCC. While, the second method considers a multiple point...

The aim of deregulation in the electric power industry is to optimize the system welfare, by introducing competitive environment, mainly among the suppliers. Developing fair and equitable real and reactive power allocation method has been an active topic of research. This book suggests current methodologies to allocate real and reactive power output of individual generators to system loads and flows. Allocation procedures presented can be used independently in deregulated power systems. The choice of the chosen algorithm depends on their limitations and suitability. The advantages of various...
