Considering cyclical nature and change rate of load on short-term electricity price forecasting
Pages: 21-26
Year: Issue:  6
Journal: Electric Machines and Control

Abstract: 为了提高电价预测精确度以提高其实用价值,在电价预测模型中引入负荷周期性和变化率因素.根据负荷对电价的影响建立基于系统负荷的短期电价预测模型,使用小波分解对负荷和电价数据进行分析处理,采用神经网络的预测方法对短期市场清算电价进行预测.考虑负荷和电价的周期特性,在预测模型输入侧增加了负荷的周期性因素.考虑负荷剧变引起的电价变化,定义综合负荷变化率影响因素并加入模型输入侧来提高预测精确度.预测实例采用实...
