It is a custom power device used in power distribution networks to protect consumers from sudden sags (and swells) in grid voltage. In this paper, the controller using the P+Resonant controller and charge regulator is proposed in order to eliminate the steady-state error in DVR response and to stabilize the system, respectively. The innovation here is that the DVR with the fifteen level inverter systems protects the PCC voltage during a voltage sag condition without any real power injection into the DVR.Simulation results show the capability of the DVR to control the emergency conditions of the distribution systems.
