摘　　要：随着光伏发电的迅速发展,其接入配电网后引起的电压波动,潮流变化成为备受关注的问题。为解决光伏并网带来的不利影响,充分发挥光伏电源的优势,以网损最小为优化目标函数,以线路功率为约束条件,结合分布因子算法对光伏接入位置和极限容量进行了优化计算。最后通过算例分析证明了该方法的有效性,合理接入光伏电源可改善系统电压质量和减少网损。With the rapid development of photovoltaic generation,much attention has been paid to the PV connected as it causes voltage fluctuation and changes the power flow. In order to solve the adverse effects brought by grid connected photovoltaic,meanwhile give full use to the advantages of photovoltaic power,we choose the net loss minimum as the optimization objective function,power line carrier flow as the constraint conditions,combined with distribution factor theory for optimization and calculation of the photovottaic ac- cess locations and allowed capacity.Finally,the numerical example is presented to demonstrate the proper connection of the photovottaic power can improve the voltage quality of the system and reduce the network loss.The method is proved to be effective.
