摘要(Abstract)：
随着分布式光伏发电规模的不断扩大,渗透率不断提高,分布式光伏并网带来的配电网电压越限问题已不容忽视。首先分析了分布式光伏电源接入配电网引起电压越限的基本原理,并针对电压越限问题,对比常用的电压控制方法和控制策略,提出分布式电抗器电压控制方式,然后通过BPA稳态仿真分析了电抗器的接入位置、接入容量对调压效果的影响,最后通过抽样分析不同线路型号和线路长度下所需的串联电抗器与并联电抗器的容量大小分布、容量差值分布等特征。
With the continuous expansion of the scale and penetration of distributed photovoltaic power generation, the voltage overlimit of distribution networks due to grid integration of distributed PV can no longer be ignored. This paper analyzes the basic principle of voltage overlimit caused by the access of distributed photovoltaic power to the distribution network, and compares the advantages and disadvantages of the commonly used voltage control methods and control strategies and proposes the voltage control method of distributed reactor; then it analyzes the influence of the access location and capacity of reactor on the voltage regulation effect through BPA simulation. At last, the distribution of capacity size and capacity difference between series reactors and shunt reactors under different line types and line lengths are analyzed by sampling.
