ABSTRACT
Intelligent systems applications have received increasing attention in various areas of power systems, such as operation, planning, control, and management. This chapter focuses on the application examples of intelligent technologies in Japanese power system utilities. It describes the situation of intelligent methods application in the Japanese power system, and addresses artificial intelligent applications in power system planning and control/restoration. A certain number of actual implementations of intelligent systems is working toward better and more reliable solutions for problems in power systems. After implementation of an intelligent system, the investment for system expansion is reduced because of the efficient utilization of already existing devices and equipment. The intelligent load forecasting system, actually implemented in one of the Japanese utilities, is composed of several neural networks for considering the changes of load configurations, depending on the seasons, such as spring, spring to summer, summer, summer to autumn, autumn, and winter.
