基于负荷曲线分布特征,运用模糊隶属度函数法划分峰谷时段,结合集合分类思想,引入阀值指标函数确定时段区间。借鉴已实施时段划分方案的特点,提出修正策略,对一些难以界定时段属性的点进行调整,得到4个季度的峰谷时段划分方案。考虑4个季度的用电差异性,提出采用加权二范数函数法的全年综合峰谷时段划分模型。结合某地区实例分析,证明综合时段划分方案比已实施的时段划分方案更符合负荷曲线分布特征,能有效地激励用户的需求响应。
基于負荷麯線分佈特徵,運用模糊隸屬度函數法劃分峰穀時段,結閤集閤分類思想,引入閥值指標函數確定時段區間。藉鑒已實施時段劃分方案的特點,提齣脩正策略,對一些難以界定時段屬性的點進行調整,得到4箇季度的峰穀時段劃分方案。攷慮4箇季度的用電差異性,提齣採用加權二範數函數法的全年綜閤峰穀時段劃分模型。結閤某地區實例分析,證明綜閤時段劃分方案比已實施的時段劃分方案更符閤負荷麯線分佈特徵,能有效地激勵用戶的需求響應。

Based on the distribution of the load curve,this paper uses the fuzzy membership function method to divide the peak-valley time period. Combined with a collection of classified ideas, the paper introduces a threshold index function to determine the time period. By reference to the characteristics of the time period partition scheme which has been implemented, the paper presents correction strategies to adjust some points which are difficult to define the time attribute. Considering differences of electricity consumption in four quarters, the paper proposes an annual consolidated peak-valley time period partition model by the weighted two-norm function method. Studies of a regional case prove that the integrated program is better in line with the distribution of load curves and can effectively stimulate the users’demand response.
