Energy Management System Family for Smart Grids: Concept and Validation（2）

       The 6th Asia-Pacific Power and Energy Engineering Conference (APPEEC 2014)——It is no doubt that the Energy Management System (EMS) has taken a crucial role in the Electrical Power Control Center (EPCC) as a brain to manage and control the power grid in a secure and economical way. Conventionally, the EMS is centralized one with centralized information and centralized decision-making. However it is difficult for it to treat mass information and do much faster decision in the future smart grid environment. A new concept and distributed architecture of future EMS for smart girds, i.e. EMS family covering all sections of smart grids (e.g. generation, transmission, distribution, micro-grid and demand), are proposed. Several new members of EMS family are introduced, i.e. wind farm EMS, substation EMS and electric vehicle (EV) EMS for autonomous energy management of large-scale wind farm, smart substation and large-scale EV aggregator. Both commonness and individuality of these EMS family members are discussed.
