考虑负荷可调节度的年综合峰谷电价模型研究

Annual Comprehensive Peak-valley Price Model Considering the Load Adjustable Degree

目前涉及峰谷电价的文献对全年峰谷电价的综合模型缺乏研究,且传统的电价模型仍存在一些不合理的地方,需要继续完善和改进。本文考虑一年4个季度的用电差异性,按各个季度对供电压力的大小来取其权值,提出运用加权二范数对全年的峰谷时段进行划分,从而得到全年综合时段划分方案。提出地区负荷用电可调节度的概念,并将其引入模型作为新的约束条件,提出采用变权重加权法进行多目标优化,建立全年的峰谷电价优化模型。结合某地区实例分析,证明本文模型比已实施的峰谷电价方案具有更好的削峰填谷效果。

Currently, the literature on peak-valley price is lack of research on the annual comprehensive model of TOU. In consideration of the differences between the four quarters of electricity service condition, according to the electricity amount of each quarter to take the weight, using a weighted two-norm function method to divided peak-valley time periods of the year. This paper considers regional electricity load adjustable, taking it as a new constraints of the new mode. The year＇s peak-valley price model uses the adaptive variable weight weighting method to solve the multi-objective problem.Through the study of the cases of a certain area to prove that the model has better peak effect than the peak-valley price scheme has been implemented.
