摘　　要：配电自动化系统建设与电网扩容需要巨额投资,往往不可能在短时间内完全到位,因此电网公司应对其制定长期规划。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,该文提出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进度。在24节点系统上对提出的方法进行测试,并对比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。The huge investment is required in the construction of the distribution automation system and the grid capacity expansion,however,it is often impossible to complete it in a short time.Hence the grid company should make long-term plans for the development of distribution system.As there is a coupling relationship between distribution automation system planning and grid capacity expansion planning,this paper proposes a new comprehensive planning method to deal with this complex planning problem.Firstly,a mixed integer nonlinear programming(MINLP)model is established with the consideration of the dominant software and hardware infrastructure of distribution system.The objective function of the planning model is to maximize the profits of power grid companies within the planning time range.Then the genetic algorithm is utilized to solve the planning problem of distribution automation system considering grid capacity expansion,which can obtain the best scheme and schedule capacity expansion and construction.The proposed method is tested according to a 24-bus system.The performance of the proposed method is compared with another method,which carries out the capacity expansion planning first and then carries out the distribution automation system planning.The results show that the proposed method can greatly improve the profits of power grid companies with a small amount of revenue reduction.
