摘要
电力负荷预测受电网运行特性、经济发展状况、自然环境条件与社会活动等因素影响,按预测周期长短分类为日负荷预测、周负荷预测、月负荷预测、年负荷预测等,从预测范围主要分为系统负荷预测和母线负荷预测。其中,220 kV母线负荷预测(即220 kV主变变高开关每日96点负荷预测,以下简称负荷预测)是电力现货市场日前出清的重要边界条件。自2019年广东作为全国电力市场改革试点之一率先开展不定期试结算开始,其准确性显得更为重要,严重影响安全校核、市场出清和节点结算电价。
Power load forecast is affected by the operation characteristics of power grid,economic development status,natural environmental conditions and social activities,and is classified as daily load forecast,weekly load forecast,monthly load forecast,annual load forecast,etc.,and the forecast range is mainly divided into system load forecast and bus load forecast.Among them,220 kV bus load prediction(i.e.,220 k daily load prediction of 220 kV transformer high switch,hereinafter referred to as load prediction)is an important boundary condition recently cleared in the power spot market.Since 2019,Guangdong,as one of the pilot national power market reform,took the lead to carry out irregular trial settlement,its accuracy is more important,seriously affecting the safety verification,market clearing and node settlement electricity price.
