Problems solved by technology
[0002] Clean energy has been vigorously developed due to its environmental protection and renewability, but at the same time there are many problems. Among them, the randomness and volatility of wind power will cause wind power grid connection to cause impact on the grid, and the energy utilization rate is low, so It is of great significance to study wind power consumption methods to reduce wind curtailment
[0003] The virtual power plant uses advanced communication technology to gather and control various comprehensive energy sources scattered in the region, forming a power generation and distribution system with excellent controllability, providing an effective way for wind power consumption, because the power generation and distribution system uses electricity, The continuous growth of multiple types of loads represented by thermal loads has caused the operation of virtual power plants to be coordinated and optimized

The invention discloses a virtual power plant wind power consumption method considering power and heat load comprehensive demand response. The method comprises the steps of establishing a fan output model to obtain a wind power prediction curve; establishing a heat load demand model before / after demand response and a heat supply equipment output model before / after demand response, and acquiring a wind curtailment amount at each moment before / after demand response and the total wind curtailment amount before / after demand response; judging whether consumption is promoted or not according to the total wind curtailment amount before / after the demand response; and establishing a storage capacity model to judge the charge-discharge state and the charge-discharge capacity of a storage battery. According to the invention, electricity and heat can be reasonably guided, an energy utilization rate is improved, and the operation cost of a virtual power plant is reduced; in the aspect of theoretical analysis, the method has a reference value for wind power consumption of the virtual power plant considering various loads to implement comprehensive demand response, and a scientific basis is provided for more effectively improving the energy utilization rate; and an effective way is provided for reducing the operation cost of power generation and distribution systems such as a virtual power plant and the like.
