Power System Technologies to Realize Smart Grid

Abstract

The approaches to Smart Grid are characterized by the following three points. That is, 1) integration of electricity and information and communication technologies (ICT), 2) handling of large integration of renewable energy, 3) cooperation between supply side and demand side. Based on the above three points, this paper summarizes power system technologies to realize Smart Grid from the viewpoint of power supply chain. Also, recent research trend of related area is surveyed. Among the large integration technologies of renewable energy, researches on the areas of centralized generation and storage, distribution and distributed generation and storage in the supply chain are very active including peripheral technologies. Among the cooperation between supply side and demand side, most of the research faces to demand area in supply chain.
