基于网格的城市配电网优化规划方法研究

摘要

科学合理的配电网规划对提高其供电可靠性和供电企业的效率及服务水平至关重要。以满足负荷近期增长需求为目标的配电网建设容易导致网架混乱，增加其运行调度困难，降低设备运维效率。通过建立配电网网格化的方法体系，在构建网格分层模型及其划分方法的基础上，提出了网格的分类建设标准和建设需求评估指标等技术标准体系，为以网格承载配电网规划、建设、运行调度、设备运维和营销管理等多个环节，实现多环节的闭环整体优化奠定基础。基于LH区供电局工程实践的分析表明了该方法体系的正确性。%A rational planning scheme is critical for reliability of system and efficiency of utility.The ideas of planning based on short-term demand are considered to be the main reason of chaos network structure, difficult operation and low maintaining efficiency.In this paper, a grid-based planning method is proposed.Based on the established hierarchical model and division method of grids, the classification standards and constructions demand evaluation indexes are proposed.Therefore, planning, construction, operation, maintenance and marketing can be performed based on girds and the closed-loop optimization of multi-links can be achieved.A engi-neering practices of distribution system planning in the LH district indicated the correctness of the method proposed in this paper.
