The invention discloses a distributed power supply optimal connection position and capacity planning method taking multiple subjects into consideration. The method includes the steps: building a distributed power supply model, namely, a prediction model of photovoltaic power generation system output; building an outer layer optimization model taking a power distribution network as a subject; building an inner layer optimization model taking a user as a subject; building a distributed power supply optimal access location and capacity solution algorithm based on a genetic algorithm. According tothe method, a distributed power supply model can be accurately built, many-sided benefits are comprehensively considered, and distributed power supply optimal access capacity and location is determined by two-layer optimization and multi-subject game. An important basis can be provided for optimal access of a distributed power supply in a power distribution network, an important foundation servesas optimal planning of an
