摘　　要：为解决中国"三北"地区供热期间"风热冲突"问题,在风电消纳困难的电网末端加装蓄热式电锅炉,利用弃风电量进行供热以促进风电就地消纳。该文以弃风消纳最大和运行成本最小为目标建立基于风电-蓄热式电锅炉联合供暖的风电消纳多目标优化模型,提出双层优化求解的思想,并采用改进型多目标粒子群优化算法进行求解,对生成的Pareto解集使用模糊隶属度法进行筛选。基于中国吉林省某示范工程的实际数据的仿真结果验证了该方法能够有效降低运行成本,提高风电消纳水平。In order to solve"wind-heat conflict"during the heating period in"San Bei"region of China,installing electric boiler with thermal storage in the end of grid where wind power was difficult to consume and using the wind power for heat supplying to promote the accommodation of abandoned wind power. In this paper,a multi-objective optimal model was established which the objective functions are both the maximum capacity of wind power accommodation and the minimum system operation costs,and the improved multi-objective two-layer differential evolution optimization algorithm was used to solve this model. Then the scheduling of the electric boiler with thermal storage was given. Based on the real data in the power grid of northern China,the simulation result showed that it can effectively reduce system operation costs and improve wind power utilization.
