Method and device for configuring equipment capacity of electric boiler and solar heating system

The invention relates to a method and a device for configuring the capacity of an electric boiler and a solar heating system. The method comprises the following steps: obtaining the accumulated heating demand of the user; setting up the objective function and the constraint conditions of the electric boiler and the solar heating system; determining the optimal solution of the objective function which means the optimal allocation capacity of the heating equipment in the electric boiler and the solar heating system; The invention provides a method which is based on a genetic algorithm of the optimization algorithm that can be used as an optimization method for the global search of complex systems. The equipment configuration is optimized by generations and finally lowest annual cost of the combined capacity can be obtained, so that the utilization rate of energy can be improved, higher economic benefits and environmental benefits can also be achieved, and it also has important significance and reference value t
