北京郊区电网冬季典型日“煤改电”负荷特性分析

Analysis on load characteristics of“coal to electricity”in typical days of Beijing suburban power grid in winter

“煤改电”负荷在北京冬季电网负荷中的占比越来越大,负荷增长幅度远超预期值,给地区电网调度、抢修、服务等各项工作带来较大压力。为深入分析“煤改电”负荷特性,本文基于“煤改电”智能服务平台,通过研究北京某郊区电网总负荷与气温相关性、“煤改电”线路及用户用电特性,总结出该区冬季电网负荷用电规律,为地区电网负荷预测及安全可靠运行、统筹农村电网规划、提高优质服务质量提供参考依据。

The load of“coal to electricity”is becoming more and more important in Beijing’s winter power grid,and the load growth rate is far beyond the expected value,which brings great pressure to the regional power grid dispatching,emergency repair,service and other work.In order to deeply analyze the load characteristics of“coal to electricity”,based on the“coal to electricity”intelligent service platform,this paper studies the correlation between the total load and temperature,the power consumption characteristics of“coal to electricity”lines and users in a district of Beijing,and summarizes the power consumption law of winter power grid load in this district,which also provides an important reference for regional power grid load forecasting and safe and reliable operation,overall planning of rural power grid,and improving the quality of service.
