摘要: 乡村用户较为分散、用电负荷密度低,其配电网设备利用率远低于城镇。各用户负荷曲线的波动特征不同,不同用户组合后总负荷曲线的平准化程度不同,对配电网的供能范围进行优化具有提升线路和设备利用率的潜力。同时,各类需求侧负荷调控技术的应用也可调整用户的负荷曲线,减小各用户的供电峰谷差。为实现乡村配电网规划和需求侧负荷调控方案协同优化,在对农村配电网构建成本、用户需求侧负荷调控成本进行数学描述的基础上,构建了用户聚合和各用户需求侧负荷调控协同优化模型,对各用户需求调控和配网线路供能范围进行综合优化。案例研究表明,对配电网供能范围和用户需求侧负荷调控措施进行协同优化,可以明显提升农网线路及附属设备的平均利用率,减少农村电网建设成本。

Abstract: Various types of electricity users in rural areas are scattered and have low load density. The average utilization rate of power grids in the distribution networks is much lower than that in urban areas. The fluctuation characteristics of the load curve of each user are different, and the average load is different when different users are combined together. Optimizing the energy supply scope of the distribution networks has the potential to improve the utilization rate of power equipment. At the same time, various demand-side load management measures can also be applied to adjust the load curves of various users and reduce the peak-to-valley difference in power supply. In order to realize the coordinated optimization of rural distribution network planning and the demand side load management schemes, a user aggregation and user demand load management synergic optimization model is built to comprehensively optimize the energy consumption management of each user and the energy service scope of distribution network lines. The case study shows that the coordinated optimization of the energy supply scope of the distribution networks and the demand side load management measures of users can significantly improve the average utilization rate of the rural power grid lines and auxiliary equipment and reduce the construction cost of the rural power grids.
