Virtual energystorage based electric heating micro-grid connecting line power fluctuation suppression method

A virtual energy storage based electric heating micro-grid connecting line power fluctuation suppression method is disclosed. Firstly, a virtual energy storage system model of fusion heat pump, gas turbine and building energy storage is constructed by means of heat storage capacity of building on user side of electric heating micro-grid. By collecting the real-time power of renewable energy and user load, Considering the state of charge of supercapacitor and the state of virtual energy storage system, the target power of tie-line is determined to realize the power smoothing of tie-line in micro-grid. Finally, the final output of controllable equipment is given by calculating and correcting the pre-output of controllable equipment. The invention can regulate the output of the virtual energystorage system while meeting the constraint of the room temperature, and distributes the fluctuating power of the tie line of the electric heating micro-grid between the virtual energy storage (heatpump, micro-gas turbine) a
