摘要

计及分布式电源输出功率的不确定性,提出一种含分布式电源的配电网网架规划方法。依据模糊理论分别建立风机机组输出功率模型及光伏发电输出功率模型。以年平均投资运行费用模糊期望值最小为目标函数,以渗透率约束、节点电压、网络拓扑约束和潮流平衡为约束条件,建立含分布式电源的配电网网架规划模型。采用融合基于边界值的配电网模糊潮流算法和模糊期望值理论的潮流计算方法,利用遗传算法改进整数编码方式求解。仿真算例表明所提方法的可行性和实用性。
        The uncertainty impacts of the distributed generations are considered to establish a configuration planning method for the distribution systems. Based on the fuzzy theory, the active and reactive power models of wind-driven generators and photovoltaic cells are formulated. Moreover, the minimum value of the annual average operating cost and the fuzzy expectation value are formulated as objective function, and the nodal voltage, network topology constraints and tidal current balance are formulated as constraints in the planning model. In accordance with fuzzy expectation value theory and boundary value-based distribution network, the fuzzy power flow calculation method is used to improve the integer coding method by genetic algorithm. Simulation examples show the feasibility and practicability of the proposed method.
