摘要
Abstract During the heating season in the “Three North” area of China, the wind curtailment has become a serious problem due to the lack of space for grid-connected wind power. Firstly, from the perspective of improving the acceptance capacity of wind power curtailment, this paper establishes a model of hybrid energy storage. Then considering the influence of the frequently changing electrodes of the regenerative electric boiler on its working life, this paper introduces the optimization coefficient of electrodes, and the optimal operation strategy of hybrid energy storage system is put forward. Finally, based on the actual data of 200 MW wind farm, this paper compares and analyzes the advantages and disadvantages of different control methods. The results show that the proposed method can further improve the power system's ability to accept wind power, under the requirements of meeting the heating demand and reducing the number of electrode adjustment of electric boilers.
