Abstract: From the Publisher:
This book offers an introduction to applications of fuzzy system theory to selected areas of electric power engineering. It presents theoretical background material from a practical point of view and then explores a number of applications of fuzzy systems. Most recently, there has been a tremendous surge in research and application articles on this subject. Until now though, there have been no books that put together a practical guide to the fundamentals and applications aspects. ELECTRIC POWER APPLICATIONS OF FUZZY SYSTEMS presents, under one cover, original contributions by authors who have pioneered in the application of fuzzy system theory to the electric power engineering field. Each chapter contains both an introduction to and a state-of-the-art review of each application area.Sponsored by:IEEE Power Engineering Society.

TL;DR: In this article, a system that monitors and controls electrical power consumption that will be retrofitted to a typical consumer electrical power arrangement (typical arrangement-electrical feed line from a provider, a meter, a circuit breaker and individual input wiring to a plurality of electrical devices, appliances and outlets).
Abstract: A system that monitors and controls electrical power consumption that will be retrofitted to a typical consumer electrical power arrangement (typical arrangement-electrical feed line from a provider, a meter, a circuit breaker and individual input wiring to a plurality of electrical devices, appliances and outlets). The system includes a control unit which receives information from an electromagnetic pickup device from which real time electrical consumption is determined over very short periods of time. The control unit has a main data processing and storage processor for retaining information and it may include a communication microprocessor for sending signals to corresponding modules. The electromagnetic pickup device uniquely measures the electromagnetic flux emanating at each output wire from each of the individual circuit breakers in a breaker box. The modules have filters which release electrical power to the individual electrical devices, appliances and outlets at a controlled, economic rate.

TL;DR: Simulation results indicate that the proposed EM strategy exhibits similar behavior as an optimal solution obtained from dynamic programming, and this concept applies to many existing HEVs as well as possible future vehicle configurations.
Abstract: Hybrid electric vehicles (HEVs) are equipped with multiple power sources for improving the efficiency and performance of their power supply system. An energy management (EM) strategy is needed to optimize the internal power flows and satisfy the driver's power demand. To achieve maximum fuel profits from EM, many solution methods have been presented. Optimal solution methods are typically not feasible in an online application due to their computational demand and their need to have a priori knowledge about future vehicle power demand. In this paper, an online EM strategy is presented with the ability to mimic the optimal solution but without using a priori road information. Rather than solving a mathematical optimization problem, the methodology concentrates on a physical explanation about when to produce, consume, and store electric power. This immediately reveals the vehicle characteristics that are important for EM. It is shown that this concept applies to many existing HEVs as well as possible future vehicle configurations. Since the method only focuses on typical vehicle characteristics, the underlying algorithm requires minor computational effort and can be executed in real time. Clear directions for online implementation are given in this paper. A parallel HEV with a 5-kW integrated starter/generator (ISG) is selected to demonstrate the performance of the EM strategy. Simulation results indicate that the proposed EM strategy exhibits similar behavior as an optimal solution obtained from dynamic programming. Profits in fuel economy primarily arise from engine stop/start and energy obtained during regenerative braking. This latter energy is preferably used for pure electric propulsion where the internal combustion engine is switched off.
