The impact of extreme weather condition on the voltage regulation in distribution systems with high penetration of roof-top photovoltaic

With the rapid growing penetration of solar power, extreme weather conditions may cause disturbance to power grids. Previous works have studied the impact of extreme weather conditions on active power balance at transmission level, while few studies investigated the potential voltage issue in distri...
