INTEGRATED ENERGY SYSTEM OPTIMIZATION METHOD BASED ON HEATING GRID AND HOME THERMAL INERTIA

Disclosed is an integrated energy system optimization method based on a heating grid and home thermal inertia, comprising the following steps: step 10: establishing a heating-grid model which takes transmission delay into account and a building model which takes heat storage properties into account; step 20: providing combined cold-heat-and-power to a system model, the heating-grid model, and the building model, and establishing an integrated energy system optimization model; step 30: using the integrated energy system optimization model to solve for an optimal scheduling plan, and according to said optimal scheduling plan, controlling the output of a gas turbine and a gas boiler on an hourly basis, and purchasing electric power from the electrical grid and a wind farm. In the method, a heating grid and a user are included in the scope of scheduling; thus the adjustment of the loads of multiple degrees of freedom is achieved, system operating flexibility is increased, and a greater margin is provided for the
