能源互联网背景下电网负荷预测设计

Power Grid Load Forecasting Design Based on Energy Internet

能源互联网的提出与发展,决定了电力系统的核心地位。作为电力系统及其自动化的重要研究方向之一,电力系统负荷预测必须符合当前能源互联网的战略布局调整。选取四川省西昌市作为电网负荷预测研究对象,采用灰色数学理论,建立了该地区电网负荷预测数学模型,并应用实例详细介绍了数学模型精度分析、预测值与实际值之间的误差分析以及未来几年内该地区的负荷预测结果。仿真分析结果表明本算法具有较好地预测精度,对该地区电网负荷规划具有一定的辅助指导作用。

The development of the energy Internet determines the core position of the power system. As one of the important research directions of power system and automation, power system load forecast must be in line with the current strategic layout of the energy Internet. This paper selects Xichang city in Sichuan Province as the research object of power network load forecasting, and uses the grey mathematical theory to establishes the mathematical model of load forecasting in the area. Then it introduces the precision analysis of the mathemati- cal model, as well as the error analysis between the prediction value and actual value, and the load prediction results of the region in the next few years. Simulation results show that this proposed algorithm has good prediction accuracy, and provides a certain auxiliary.
