Park integrated energy system game optimization operation strategy considering wind and light uncertainty and stepped demand response

The invention provides a park integrated energy system game optimization operation strategy considering wind and light uncertainty and stepped demand response, and the strategy comprises the following steps: 1, constructing a park integrated energy system frame, and carrying out the modeling of a gas turbine, a gas boiler, an energy storage device and wind and light uncertainty in the constructed PIES frame; 2, constructing a stepped demand response model according to the user aggregator side load; 3, constructing a master-slave game model of a park operator and a user aggregator in PIESPIES, and taking the park operator as a leader and the user aggregator as a follower; step 4, establishing a target function by taking the maximum daily operation net income of the park operator as an optimization target, establishing a target function by taking a user aggregator as a follower and taking the minimum daily energy consumption cost as an optimization target, and constraining the PIES in the optimization schedulin
