Method for establishing optimal response model of electro-thermal coupling microgrid by comprehensively considering reliability and economy

The invention discloses a method for establishing an optimal response model of an electro-thermal coupling microgrid by comprehensively considering reliability and economy. The electro-thermal coupling microgrid comprises a microgrid, a heat supply network and an electric boiler. The microgrid comprises an electric load, an electric energy bus for supplying power to the electric load, distributedphotovoltaics, an electricity storage device and a tie line connected with a superior power grid. The heat supply network comprises a heat energy bus, a heat load and a heat storage device. The electric boiler is connected with the electric bus and the heat bus. The method comprises the following steps: S1, establishing an output model of each element in the electro-thermal coupling microgrid; S2,establishing an electric heating combined response mechanism; S3, evaluating the reliability and economy of the electro-thermal coupling microgrid based on the electro-thermal joint response; S4, establishing an electricity-h
