Electricity is the prime mover of a modern society. Per capita consumption of electricity is an indicator of a countrys growth. This indicator depends on availability, quality and reliability of power and most particularly its overall cost. The cost ofelectricity governs its usage. Thus the electricity pricing is a major issue to consumers for its liberal use. But due to demand of social and technological advancements the changes in power networks and their mode of operation are inevitable. Revolutionize of electric power industries engross technical and also various non-technical and economic issues. Even though as an inevitable consequence, power networks have been undergoing changes from regulated to de-regulated structures, finally stepping into smart grid concept which in turns, involves the change in electricity price methodology-- This book provides proven methods for supplying uninterrupted, quality power at a reasonable price to the consumer. Taking into consideration operating constraints as well as generation cost, line overload, and congestion for expected and inadvertent loading stress, the text presents solutions based on stochastic optimization techniques--such as genetic algorithm, particle swarm optimization, and differential evolution--for improving the stability, reliability, and efficiency of LPS and deregulated multi-bus networks. It also proposes the use of stochastic techniques in optimizing utility management in the smart grid-- Electricity Pricing: Regulated, Deregulated and Smart Grid Systems presents proven methods for supplying uninterrupted, high-quality electrical power at a reasonable price to the consumer. Illustrating the evolution of the power market from a monopoly to an open access system, this essential text:Covers voltage stability analysis of longitudinal power supply systems using an artificial neural network (ANN)Explains how to improve performance using flexible alternating current transmission systems (FACTS) and high-voltage direct current (HVDC)Takes into account operating constraints as well as generation cost, line overload, and congestion for expected and inadvertent loading stressGoes beyond FACTS and HVDC to provide multi-objective optimization algorithms for the deregulated power marketProposes the use of stochastic optimization techniques in the smart grid, preparing the reader for future developmentElectricity Pricing: Regulated, Deregulated and Smart Grid Systems offers practical solutions for improving stability, reliability, and efficiency in real-time systems while optimizing electricity cost.
