考虑多主体利益与需求响应的分布式电源优化配置

Distributed generation planning in an active distribution network considering multi-agent interests and demand response

传统的分布式电源规划仅考虑单一利益主体,且未考虑需求响应,无法兼顾各市场主体的利益需求且忽略了负荷的调节能力。针对以上问题,提出了一种考虑多主体利益和需求响应的分布式电源优化配置模型。首先,结合电源侧的环境成本和用户侧的需求响应,分别以分布式电源发电企业、配电公司、电力用户的净收益最大为目标,建立各自的优化配置模型。其次,根据三者的利益关系,构建可同时兼顾三者净收益的综合优化目标,并采用二阶锥规划方法进行求解。最后,以IEEE33节点配电网作为算例,结合某地区电网的实际数据进行仿真分析。结果表明:所提出的优化配置模型可有效提升各主体的整体经济效益,并且可保证主体间的利益均衡,有助于提升电力市场的活力。

For traditional distributed energy planning,it is common to only consider a single interest subject.Demand side response is not effectively considered,and especially the interests of various market entities and load regulation ability are absent.To take these issues into account,a novel planning model considering multiple interests and demand response is proposed.First,in terms of the environmental cost on the power supply side and the demand response on the user side,optimal configuration models are established to maximize the net incomes of distributed generation enterprises,distribution companies and power users.Then,a comprehensive optimization objective is designed to combine entire net incomes,and the second-order cone planning method is adopted to solve the problem.Finally,the IEEE33 node distribution network combined with the actual data of a regional power grid is used to test the effectiveness of the proposed model.The results show that the proposed model can effectively improve the overall economic benefits and balance the interests among different interests,and thus the vitality of the power market is well enhanced.
