居民用户对分时电价的响应潜力评价方法

Demand Response Potential Evaluation Method of Time-of-use Price for Residential Community

为了适应智能电网的发展,促进需求侧资源的合理利用,在分时电价下选取居民小区用户为研究对象,从时间尺度上提出一种刻画其需求响应潜力的指标和综合评价方法。评价指标从需求响应能力和速度2个角度定义了用户每个时段的需求响应潜力,运用经济学中的需求价格弹性矩阵,得到需求响应能力的计算方法。建立分时电价下居民小区综合需求响应潜力的评价模型。该方法实现对居民小区需求响应潜力的量化,为居民需求侧资源的管理提供了依据,从价格的制定与峰时段的划分2个角度指导分时电价的制定。算例分析证明所提指标的合理性、评价方法的普适性与有效性。

To adapt to the development of smart grid and promote the reasonable utilization of demand side resources,based on time-of-use price,this paper selects the residential area users as the research object and proposes indexes and a comprehensive evaluation method to describe its demand response potential from time scale. The evaluation indexes define the demand response potential of user in per time period from the aspects of demand response ability and speed. Demand response ability is calculated by applying the conception of demand elasticity matrix of electricity price w hich is commonly used in economics. Finally,an evaluation model of comprehensive demand response potential in residential area under timeof-use electricity price is established. This method quantifies the demand response potential of the residential area,and provides the basis for the management of the residents＇ demand side resources. In the meantime,the results can instruct the formulation of the time-of-use price from the aspects of price setting and peak period division. The analysis of the cases has proved the rationality of the proposed indexes,as w ell as the validity and universality of the evaluation method.
