面向需求侧主动响应的工商业用户电力套餐优化设计

Design of Electricity Plans for Industrial and Commercial Customers Oriented to Active Demand Response on Power Demand Side

电力需求响应是应对电网峰谷差持续拉大、间歇性可再生能源大规模并网、能源结构转变等问题的有效方法。为此,提出了一种新的需求侧主动响应策略——面向工商业用户的电力套餐,并对电力套餐的设计问题进行了优化研究。首先,采用基于特性指标降维的负荷聚类方法辨识工商业用户的负荷特征,为电力套餐的设计进行市场细分;其次,在综合考虑电费支出满意度和用电方式满意度对用户决策的影响的基础上,基于多项Logit模型构建用户对电力套餐的选择行为模型;接着,构建基于成本—效益分析的电力套餐综合评估模型,以衡量电力套餐的经济价值;然后,在此基础上,提出以最大化益本比为优化目标的电力套餐设计的优化模型。算例采用某地区工商业用户的实际数据,结果显示了所提电力套餐的经济价值及其调动需求侧主动参与负荷管理的效果。

Demand response (DR)is regarded as one of the most important solution to the increasing peak-valley differences, grid-connection of large-scale renewable energy sources and transformation of energy structure.Therefore,a novel DR plan is proposed,which is named as electricity plans for industrial and commercial customers.The design of electricity plans is studied in depth.In order to obtain market segmentation,pattern index clustering is used to identify the load characteristics of industrial and commercial customers.Taking customer satisfaction with electricity bills and the way of electricity consumption into account,a customer choice behavior model based on multinomiai Logit model (MNL)is built.To measure the economic value of electricity plans,a comprehensive evaluation model for electricity plans is proposed based on cost-benefit analysis.On this basis,an optimization model for designing electricity plans is established,in which maximizing the benefit cost ratio is taken as the optimization objective.Finally,a case is studied to verify the economic value and the role of the active participation in load management of electricity plans.
