摘要
在我国风电渗透率较高的地区电网中,由于风电具有反调峰特性,危害电力系统安全运行,电源侧调节资源逐渐匮乏,挖掘分布式电采暖负荷调峰能力,是解决该问题的有效途径。文章建立基于建筑参数的电采暖负荷模型以及调峰能力评估模型,然后进行调峰实验验证可行性并拟合严寒地区模型参数,最后基于仿真,从时移电量和调峰成本两方面描述严寒地区典型居民楼调峰能力,并分析时移电量和调峰成本的影响因素。
In the regional power grid with high wind power penetration rate in China,the wind power has anti-peaking characteristics,which harms the safe operation of the power system.The source side regulation are gradually lacking,and developing the peak-shaving capability of distributed electric heating load is an effective way to solve this problem.In this paper,an electric heating load model based on building parameters and a peak-shaving capability evaluation model are established.Then the peak-shaving experiment is carried out to verify the feasibility and fit the model parameters in the severe cold region.Finally,on the basis of simulation,the peak-shaving capability of typical residential building in the severe cold region is given from two aspects:time-shift power and peak-shaving cost.And the factors affect the time-shift power and peak-shaving costs are analyzed.
