摘　　要：针对传统的电网月度电量校核存在海量数据处理复杂、高维度数据优化难等问题,提出了一种基于负荷轨迹特征的电网月度电量安全校核模型。该模型通过对电网负荷的变化趋势进行分段线性化处理,提取不同时段的负荷轨迹特征,从而缩短了月度电量校核的计算规模,从而能够提高电网月度电量安全校核效率。最后通过实际电网算例验证了所提模型的可行性和有效性。Aiming at the problem that the traditional grid monthly electricity check has complex data processing and high dimensional data optimization,a monthly grid safety check model based on load trajectory is proposed.The model performs segmental linearization on the trend of grid load and extracts the load trajectory characteristics of different time periods,thus shortening the calculation scale of monthly power check,which can improve the monthly power safety check efficiency of the grid.Finally,the feasibility and effectiveness of the proposed model are verified by an actual power grid.
