Power-to-gas equipment capacity optimization configuration method giving consideration to wind power consumption

The invention provides a power-to-gas equipment capacity optimization configuration method giving consideration to wind power consumption, and the method comprises the following steps: 1), obtaining the wind power output and the power and natural gas load data of a region last year where a power-gas combined network is located; 2), obtaining the parameters of a generator, a gas source and power-to-gas equipment in the network; 3), giving consideration to the constraint from the power-to-gas equipment, introducing a winding curtailment quantity as a penalty term, and building a power-gas combined network yearly cost optimal model; 4), solving the power-gas combined network yearly cost optimal model through employing a primal-dual interior point method, and obtaining the minimum yearly cost of the combined network and an optimization configuration capability of the power-to-gas equipment at this moment. The method provided by the invention achieves the configuration of the capacity of the power-to-gas equipment in the network, and can effectively reduce the yearly cost and wind curtailment rate.
