Wind power consumption method of virtual power plant with consideration of comprehensive demand responses of electrical loads and heat loads

A method for consuming wind power in a virtual plant with consideration of comprehensive demand response for electrical loads and heat loads, comprising the following steps:

• providing the virtual power plant which comprises an electrical boiler, a storage battery and a wind turbine;
• wherein the wind turbine is capable of supplying power to the electrical boiler and an electrical load;
• the storage battery is capable of supplying power to the electrical load, and assisting power supply to the electrical boiler;
• the electrical boiler is capable of providing heat supply to a heat load;
• establishing a wind turbine power model to obtain a wind power prediction curve;
• establishing a pre-demand-response heat load demand model and a pre-demand-response electrical boiler output model;
• determining a pre-demand-response heat load demand based on the pre-demand-response heat load demand model;
• calculating a pre-demand-response wind power consumption of the electrical boiler according to the pre-demand-response electrical boiler output model and the pre-demand-response heat load demand;
• calculating a pre-demand-response abandoned wind power per moment and a pre-demand-response total abandoned wind power according to the wind power prediction curve, a pre-demand-response electrical load demand, and the pre-demand-response wind power consumption of the electrical boiler;
• establishing a post-demand-response heat load demand model and a post-demand-response electrical boiler output model;
• determining a post-demand-response heat load demand based on the post-demand-response heat load demand model;
• calculating a post-demand-response wind power consumption of the electrical boiler according to the post-demand-response electrical boiler output model and the post-demand-response heat load demand;
• calculating a post-demand-response electrical load demand;
• calculating a post-demand-response abandoned wind power per moment and a post-demand-response total abandoned wind power according to the wind power prediction curve, the post-demand-response electrical load demand, and the post-demand-response wind power consumption of the electrical boiler;
• then obtaining a difference value between the pre-demand-response total abandoned wind power and the post-demand-response total abandoned wind power;
• promoting wind power consumption if the difference value is greater than 0;
• and
• establishing a storage battery capacity model;
• determining a charging-discharging state and a charging-discharging ability of the storage battery according to the storage battery capacity model and the post-demand-response abandoned wind power per moment.
