摘要/Abstract

摘要： 针对农村地区配电网供电可靠性低以及光伏扶贫政策下大规模分布式光伏接入引起的电压越限和潮流倒送问题，提出一种基于虚拟变电站模式的光储协调控制方法，结合河北省营里乡配电网实际工程案例，对不同运行方案下系统的稳态性能，如电压水平、网络损耗等进行了对比分析，并基于蒙特卡洛模拟验证了所提方法对农村配电网供电可靠性提升的有效性。

Abstract: In view of the low reliability of power supply in rural distribution network and the problem of voltage overrun and power flow reversal caused by large-scale distributed photovoltaic access under the policy of photovoltaic poverty alleviation, a coordinated control method of optical storage based on Virtual Substation mode is proposed. Combining with the actual engineering case of Yinglixiang distribution network in Hebei Province, the steady-state performance of the system under different operation schemes, such as voltage level and network loss, is analyzed. The effectiveness of the proposed method to improve the reliability of rural distribution network is verifed by Monte Carlo simulation.
