    摘要:

    配电自动化系统建设与电网扩容需要大量资源,需对其进行长期规划。配电自动化系统规划与电网扩容规划之间存在耦合关系,为了处理这一复杂的规划问题,本文提出了一种新的综合规划方法。首先考虑配电系统的主要软硬件基础设施,建立了混合整数非线性规划(MINLP)模型。规划模型的目标函数是在规划时间范围内最大化电网公司的利润。然后利用遗传算法求解考虑电网扩容后的配电自动化系统规划问题,确定电网扩容以及自动化系统建设的最佳方案和时间表。在24节点系统上对提出的方法进行了测试,并对比了先进行电网扩容规划再进行配电自动化系统规划的方法,所提出的方法可在少量减少收入的情况下大幅提高电网公司的利润。

    Abstract:

    The construction of distribution automation system and the grid capacity expansion need a lot of resources, and it needs to be planned for a long time. There is a coupling relationship between distribution automation system planning and grid capacity expansion planning. In order to deal with this complex planning problem, a new comprehensive planning method is proposed in this paper. Firstly, considering the main software and hardware infrastructure of distribution system, a mixed integer nonlinear programming (MINLP) model is established. The objective function of the planning model is to maximize the profits of power grid companies within the planning time range. Then genetic algorithm is used to solve the planning problem of distribution automation system considering grid capacity expansion, and the best scheme and schedule of grid capacity expansion and automation system construction are determined. The proposed method is tested on a 24-bus system, and the methods of grid capacity expansion planning and then distribution automation system planning are compared. The proposed method can greatly improve the profits of power grid companies with a small amount of revenue reduction.
