电力系统短期负荷预测系统的实现

Implementation of Short Term Load Forecasting System in Power System

考虑近期我国电力市场需求,开发了电力系统短期负荷预测软件系统.该系统分为原始数据维护、负荷预测和预测结果处理3个相互独立模块.在数据库设计中,采取定期转储的办法控制数据量.系统提供了丰富的模型库,各模型可单独预测,也可选择几种模型进行综合预测.河南省某县级电力系统的负荷预测结果表明,该系统能够取得满意的预测效果.

Taking account of the demand of electricity market in China, a design of short term load forecasting system is presented in this paper. This system consists of three independent modules: original data maintenance module, load forecasting module and forecasting result processing module. The load forecasting module consists of many models and each model can be independently used or some of them can be combined for integrated forecasting. The results indicate that satisfactory forecasting accuracy can be achieved with this system.
