Abstract

The invention relates to a microgrid interaction system which comprises an energy management system and a competition management system. The energy management system is used for acquiring electric power information and environment information for making first participatory interaction energy information. The competition management system is used for receiving the environment information for predicting energy requirement information of the microgrid in a next time period. The competition management system is also used for receiving second participatory interaction energy information, analyzing an interaction probability and making an interaction strategy. The microgrid interaction system and the microgrid interaction method can supply a good accessing environment for user-side power consumption equipment and distributed energy resources, thereby realizing benefit for power grid and users.
