电力系统负荷预测方法研究与分析

负荷预测是电力系统规划和运行研究的重要内容,负荷预测的准确程度将直接影响到投资、网络布局和运行的合理性,其是保证电力系统可靠供电和经济运行的前提,是电力系统规划建设的依据,基于此分析了基于BP网络的短期负荷预测方法与基于灰色预测的中长期负荷预测方法。

Research and Analysis on the Load Forecasting Method of the Electric Power System

Load forecasting is important content of the plan and research of electric power systems. The accuracy of the load forecasting will directly affect the rationlity of investment, network topology and operation, which is to ensure the premise of reliable power supply of the electric power system and economic operation and the basis for the planning development of the electric power system. For this, the paper analyzes short-term load forecasting method based on BP network and medium and long term load forecasting methods based on the grey forecast.
