Day-Ahead Scheduling Strategy Optimization of Electric–Thermal Integrated Energy System to Improve the Proportion of New Energy

The coordinated use of electricity and a heat energy system can effectively improve the structure during winter heating in northern part China environmental pollution problem. In this paper, an economic scheduling model electric–thermal integrated system, including wind turbine, regenerative electric boiler, solar collection biomass ground source pump battery is proposed, boiler was selected as auxiliary system. A mixed integer linear programming established to take operating cost whole target. day-ahead optimization strategy considering demand side response improving new consumption proposed. order verify influence utilization flexible load storage equipment on optimal built, three scenarios were set up. Scenario 3 contains load. Compared with scenario 1, total reduced by 51.5%, abandonment 43.3%. reduce consumption. By increasing capacity energy-storage device, power completely absorbed, but operation maintenance increased, so allocated reasonably according actual situation.
