Abstract

Smart Grid System is very important system for optimal utilization of electricity. As a point of view of national electricity supply and demand side management, smart grid system acts as the best tool not only to reduce electrical generation, substations and transmission but also to save national energy consumption. In this article, necessities and basic concept of electrical smart grid system including "Demand Response" are introduced. Demand Response is a change in the power consumption of an electric utility customer to better match the demand for power with the supply. Electric energy can not be easily stored, so utilities have traditionally matched demand and supply by throttling the production rate of their power plants, taking generating units on or off line, or importing power from other utilities. And also, in this article some case studies for Demand Response Projects Including PV and ESS Combined Case are presented.
