The large number of distributed generations connected to the power grid brings problems reverse flow and voltage rise. Due existence "negative regulating effect", traditional on-load tap changer (OLTC) needs reactive compensation device make good regulation. In this paper, flexible OLTC with back-to-back source converter (BTB-VSC) technology can generate a certain without device, which achieve better regulation effect. Meanwhile, based on principle sensitivity partition, we propose coordinated control strategy generators (DG), coordinate action DG. simulation model system operation is built in Simulink software, research results show that effect be achieved through coordination
