Abstract

The invention discloses a wind power consumption strategy obtaining method for a comprehensive energy virtual power plant. The method comprises the steps: S1, constructing an electric-thermal couplingtype virtual power plant structure containing a combined heat and power generation unit and a ground source heat pump; S2, analyzing thermal delay, transmission loss and heat storage characteristicsof the internal heat energy transmission process of the electro-thermal coupling type virtual power plant, and performing dynamic modeling; S3, constructing a wind power consumption model of the electric-thermal coupling type virtual power plant in combination with the operation characteristics of the combined heat and power generation unit and the heat pump; S4, solving the wind power consumptionmodel to obtain an output scheme of each energy device in the electro-thermal coupling type virtual power plant, and performing real-time adjustment. By implementing the method, the wind power consumption level of the system can be improved, and the total energy consumption cost of the system within one day is reduced.

Description

technical field [0001] The invention relates to the technical field of power dispatching, in particular to a wind power accommodation strategy for an integrated energy virtual power plant. Background technique [0002] In recent years, the installed capacity of renewable energy represented by wind power has developed rapidly. According to the statistics of the World Wind Energy Association, since 2000, the annual growth rate of global wind power installed capacity has remained above 10%, which has also brought about serious problems of wind power consumption. In Jilin Province, combined heat and power units supply more than 70% of the heat load, and their operation is often constrained by heat-based electricity, with limited regulation capacity and unable to complement wind power generation, seriously affecting the wind power acceptance capacity. With the further increase of wind power development in the future, the problem of wind power consumption will become more promine...
