考虑可转移负荷的售电公司负荷组合优化

Combinatorial Optimization Strategy of Power Sales Company Considering Transferable load

在电力市场环境下,售电公司根据用户的负荷特性,进行用户负荷的组合优化可以降低售电公司的购电成本,从而提升售电公司效益。针对售电公司如何根据电力负荷的互补性、多样性整合优化用户资源的问题,从降低购电成本,提高售电公司效益角度,首先分析了负荷率对购电成本的影响,接着基于用户综合负荷特性,构建售电公司初步负荷组合优化模型,再进一步考虑了用户可转移负荷,对用户的组合负荷特性进行优化,最大化售电公司售电利益,最后根据某市2019年工业用户群组负荷数据,对提出的模型进行仿真分析,并对研究实施的软件功能架构进行了设计。

Under the environment of power market,the power sales company optimizes the combination of loads according to the load characteristics of the user,which can reduce the power purchase cost of the power sales company,thereby improving the efficiency of the power sales company.In order to integrate and optimize user resources according to the complementarity and diversity of power load,from the perspective of reducing the power purchase cost and improving the efficiency of the power sales company, a user load combinatorial optimization model is proposed according to the impact of the load rate on the power purchase cost and the analysis of users’ load characteristics.And the transferable load is further considered to optimize the users’ integrated load characteristics and increase the electricity benefits of power sales companies.Finally,the correctness and superiority of the model is verified using load data of a city’s industrial user group in 2019.
