基于灰色综合评价法的需求响应项目规划评估

摘要

The role of demand response as a dynamic resource in the electricity market has been paid more and more at-tention.Considering the problem of evaluation on the demand response projects,an evaluation method for demand re-sponse projects is proposed in this paper based on gray comprehensive evaluation method.An improved model of users' demand response is established based on price elasticity matrix,and the demand response evaluation indexes are con-structed considering both the performance and economic indexes.An evaluation technique based on entropy method and gray comprehensive evaluation method is used to select the project that matches with the evaluation objectives most from many demand response projects.Typical cases are provided to show the evaluation process of demand response in differ-ent scenarios and with different objectives,and the evaluation results are explained in depth from the perspectives of both the program rules and the evaluation objectives,which proves the effectiveness and practicality of this model.The proposed evaluation method can provide technical support for the decisions on demand response planning and the pro-motion of projects.%需求响应作为一种动态资源在电力市场中的作用越来越受到重视.本文针对需求响应项目规划评估问题,提出了基于灰色综合评价法的需求响应项目规划评估方法,建立了基于价格弹性矩阵的用户响应特性改进模型,构建了计及效果指标及经济指标的需求响应规划评估指标.应用熵权法和灰色综合评价法的评估技术,在多个需求响应方案中选出与规划评估目标最匹配的需求响应项目.通过典型案例对多场景不同规划目标下的需求响应项目的效果效益进行综合评估,并结合项目规则和规划评估目标,对评估结果进行了深层解释,证明了评估模型的有效性和适用性.该评估方法为需求响应规划决策和项目的推广提供了技术支撑.
