摘　　要：为解决"三北"地区供热期间"风热冲突"问题,提高风电就地消纳能力,提出在风电消纳困难的电网末端加装蓄热电锅炉,利用弃风电量进行供热以增加风电并网空间,并考虑区域间的电功率交换及多种机组约束,多区域综合调度,以系统发电成本最低为目标函数,构建多区域热–电模型,给出蓄热电锅炉的运行方式。基于我国北方某省级电网数据,验证电供热系统提高风电并网能力的有效性;分别仿真分析配置普通电锅炉和蓄热电锅炉的效果,说明蓄热装置对于电供热系统及风电并网的重要性;同时比较不同调度起止时间下风电并网及蓄热电锅炉运行状态的差异,结果显示在风电大发时刻即启动蓄热电锅炉能提高装置利用率。In order to solve ＂wind-heat conflict＂ during the heating period in the ＂San Bei＂ region of China and improve the local wind power accommodation ability, this paper proposed the method of installing electric boilers with thermal storage in the end of grid where wind power was difficult to consume. Wind power was used for heat supplying during the wind power curtailment period. Utilizing the lowest coal consumption as the objective function, the multi-zone heat and electricity coordinated dispatch model which considered a variety of constraints including different units and transmission line was proposed. 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 verified the usefulness of the electric heating system and the effect of thermal storage, finally, compared the differences of wind power accommodation and operated conditions of electric boiler with thermal storage between different starting and ending time scheduling, the results show that starting the electric boiler at the moment of sufficient wind energy can improve the utilization of the device.
