基于分布式光伏典型日曲线的负荷预测方法研究

Research on Load Forecasting Method Based on Typical Daily Curve of Distributed PV

分布式光伏电源大规模接入电网后,在实际运行的过程中很大程度上增强了电网系统的电源支撑,但也在一定程度上增加了电网负荷预测的难度。在电网实际运行的过程中,负荷预测是保障电力系统安全稳定经济运行极为重要的一项内容,因此需不断改进负荷预测工作,提升电网调度运行水平。分布式光伏在实际运行过程中,电力资源数据的采集具有一定的难度,因此需对分布式光伏典型日曲线的负荷预测方法进行探究分析,以此提升整体负荷预测的有效性及精准度。

After large-scale distributed photovoltaic power supply is connected to the power grid system,the power supply support of the power grid system is greatly enhanced in the actual operation process,but it also increases the difficulty of load prediction to a certain extent.In the actual operation of the power grid,load forecasting is a very important content to ensure the safe,stable and economic operation of the power system,so it is necessary to constantly improve the load forecasting work and enhance the level of power grid dispatching operation.In the actual operation process of distributed photovoltaic,it is difficult to collect power resource data,so it is necessary to explore and analyze the load prediction method of the typical daily curve of distributed photovoltaic,so as to improve the effectiveness and accuracy of the overall load prediction.
