Abstract

The invention discloses an acquisition method of a wind power consumption strategy for an electro-thermal coupled virtual power plant, including the following steps: S1, constructing an electro-thermal coupled virtual power plant structure containing cogeneration units and a ground source heat pump; S2, analyzing thermal delay, transmission loss and heat storage characteristics of the internal thermal energy transmission process of the electro-thermal coupled virtual power plant, and carrying out dynamic modeling; S3, combining the operation characteristics of the cogeneration units and the heat pump to construct a wind power consumption model of the electro-thermal coupled virtual power plant; S4, solving the wind power consumption model to obtain an output scheme of each energy equipmentin the electro-thermal coupled virtual power plant, and carrying out real-time adjustment. By implementation of the invention, the wind power consumption level of the system can be improved, and thetotal energy consumption cost of the system in one day can be reduced.

Description

technical field [0001] The invention relates to the technical field of electric power dispatching, in particular to a method for acquiring a wind power accommodation strategy of an electrothermal coupling type 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 ...
