摘要 电网企业在有限的预算下进行配电网规划项目优选是配电网精准投资的关键,但目前规划项目优选很少定量考虑项目间相互关系对配电网绩效提升的影响。定义配电网规划项目效益耦合和时序关联的相互关系,并在配电网双Q规划方法的基础上,结合不同地区的供电可靠性差异化要求,以停电损失减少量衡量配电网项目提升的可靠性效益,建立综合考虑效益耦合和时序关联的多阶段多区域配电网规划项目优选模型。含多个供电区域的配电网规划项目库的算例结果验证了所建模型的合理性和有效性。 Optimal selection of distribution network planning projects for power grid enterprises under limited budget is the key for accurate investment of distribution network,but the impact of the correlation between projects on the performance improvement of distribution network is seldom quantitatively considered in current optimal selection of planning projects.The relationship of benefit coupling and timing correlation between distribution network planning projects is defined.On the basis of dual-Q planning method of distri⁃bution network and combined with different requirements of power supply reliability in different regions,the reduction of power outage loss is adopted to measure the upgrading reliability benefit of distribution network project,and an optimal multi-stage multi-area distribution network planning project selection model is built,which considers the benefit coupling and timing correlation.The case results of planning project database of distribution network with multiple power supply areas verify the reasonability and effectiveness of the proposed model.
