Microgrid Dynamic Economic dispatching Considering Wind-Solar Complementary Characteristics

The microgrid(MG) was widely concerned to solve energy pollution and scarcity crisis. A dynamic economic dispatch model considering wind and solar complementary characteristics is proposed in this paper. Firstly, the wind and solar complementary characteristics is modeled based on copula theory. Secondly, based on the correlation index of wind and solar, the complementary characteristic sample is obtained by copular function, and then eliminated based on the probability distance to obtain error scenario. So that the 24 hour dynamic economic dispatch model of MG considering uncertainty and complementary characteristic is established. Finally, an example of grid-connected MG containing various types of distributed power sources such as wind turbines (WT), photovoltaic (PV) and electrical energy storage verify the effectiveness of the proposed algorithm.
