Source-load Coordination Economic Dispatch of Hybrid Combined Cooling Heating and Power Microgrid Considering Wind Power Accommodation

In this paper, an optimal scheduling method of cold-heat-electricity combined power supply microgrid for wind power accommodation is proposed. Firstly, the principle of heat pump (HP) and integrated electric heating demand response to promote wind power accommodation was analyzed, and the source-charge cooperative operation strategy of multi-energy micro grid was constructed. The two-layer model is adopted, and the upper layer adopts price-type demand response to increase the off-load wind power consumption capacity. The lower layer takes the cost minimization as the goal, adds the demand response of heat load and the role of HP, establishes the day-ahead economic dispatching model, and determines the dispatching plan. The simulation results show the effectiveness of the proposed method in improving the revenue and wind power consumption capacity.
