PV fed ZSI based DVR Topology with ANFIS Control Strategy

The performance of present complex power system suffers with sudden current and voltage variations. The present model uses renewable source for Z - Source Inverter fed Dynamic Voltage Restorer (PV-ZSI-DVR). The proposed DVR topology dynamically compensates voltage interruptions, swell and sag to maintain the required level of voltage to the load. Here conventional DVR topology performance has been extended by incorporating the Hybrid Control technique ANFIS .The model presents the utilization of solar power for DVR operation in compensating the different voltage fluctuations. The performance of PV-ZSI- DVR with different control strategies have been compared in MATLAB/SIMULINK environment.
