Research on coordinated dispatching of wind power consumption in integrated energy system based on flexible equipment

Due to the randomness and volatility of wind power output, large-scale integration of wind power intensifies the phenomenon of wind power curtailment and power limitation, resulting in serious waste of clean energy of wind power. From the point of view of improving system flexibility, this paper takes CHP, electric boiler and heat storage device as the flexible equipment of integrated energy system, and constructs a coordinated dispatching model of comprehensive energy system with various flexible equipment for wind curtailment and absorption. The model takes into account the operation cost and purchasing cost of the system. In order to reduce wind power curtailment rate, the curtailment wind penalty cost is added to the target. Through the analysis of a variety of heating modes, based on meeting a certain load and heat load, the daily scheduling plan is optimized by minimizing the cost of the system as the goal. The influence of adding flexible equipment on wind power curtailment is analyzed. The results show that the model can improve the wind power consumption capacity and system flexibility.
