摘　　要：针对光伏微网系统中光伏并网容量的优化配置展开了深研究,以网损微增率指标对节点进行排序,采用该指标对微网中光伏电源并网进行了位置的最优配置。在选择光伏电源并网位置的基础上,将微网中光伏电源并网容量的确定转化为同时考虑电压约束和网损降低的双目标非线性优化规划问题,采用近似线性变化对目标函数进行迭代求解,实现了光伏并网容量最大化。算例仿真结果验证了所提方法的正确性和可行性。The optimization of photovoltaic （PV） connected capacity configuration in microgrid is studied. Power loss tiny-increasing rate is used to sort by node, which can be used to the position of the optimal configuration. On the basis of the chosen connected position of PV paralleling in naicrogrid, the determination of connected capacity is changed into nonlinear optimization programming problem with consideration of double objectives of the voltage constraints and power loss in the microgrid. Approximate linear iteration is conducted to objective function, maximizing the capacity of PV. The correctness and validity of the method are verified by simulation.
