摘要:

将交流配电网规划技术用于直流配电网的过程中,既要考虑配电网的传统供电规划目标和拓扑的变化,也要考虑多目标、多约束条件的变化,以及大量主动型负荷的接入引起的变化,更要考虑直流配电网的技术与应用的发展趋势。与此相对应,文章围绕一次规划的内容,首先分析、总结了直流配电网的规划目标、电源规划、负荷预测及网架规划4个方面的新需求,并提出规划与运行强耦合、规划目标多样性与动态性、一二次系统融合规划的其他新需求。然后围绕直流配电网拓扑展开讨论,提出基于母线、结构以及连接方式的拓扑分类,并对直流配电网的典型应用场景进行分析。之后对考虑多约束条件与不确定性的直流配电网规划方法进行讨论,包括不确定模型、规划与运行强耦合、多种不确定性因素等多方面的分析与总结;并围绕主动管理/需求侧管理和保护控制2个方面,对考虑(准)实时监控需求的直流配电网规划问题进行讨论。最后从技术层、信息层和设备层对直流配电网规划中尚需解决的问题进行梳理和展望,为未来直流配电网的规划研究提供借鉴和参考。

Abstract:

In the process of applying AC distribution network planning technology to DC distribution network, it is necessary to consider not only the changes of traditional power supply planning objectives and topology, but also the changes of multi-objective and multiple constraint conditions, as well as the changes caused by the access of a large number of active loads, and the development trend of DC distribution network technology and application. First of all, this paper summarizes the four aspects of power grid planning, including the integration of power grid planning, secondary planning and demand planning. Then the topology of DC distribution network is analyzed, and the topology classification based on bus, structure and connection mode is proposed, and the typical application scenarios of DC distribution network are analyzed. Then, the DC distribution network planning method considering multiple constraints and uncertainties is discussed, including the analysis and summary of uncertain model, strong coupling between planning and operation, and various uncertain factors. The DC distribution network planning considering (quasi) real-time monitoring demand is discussed in two aspects of active management / demand-side management and protection control. Finally, from the technical level, information level and equipment level, the problems to be solved in the DC distribution network planning are sorted out and prospected, which provides reference for the future planning and research of DC distribution network.

Key words: DC distribution network, new demand of technology, primary planning, topological classification, planning methods
