Abstract: A detailed review of research work has been done for wind-PV hybrid generation system (WPVHGS) to identify suitable plant structure. There is scope of optimisation of WPVHGS when feeding to grid at unbalanced voltage conditions. In addition to this, optimal sizing of battery energy storage (BES) and supercapacitor (SC) is required for the same. To support the review, simulations are carried out on MATLAB Simulink for comparative analysis of impact on grid due to EV charging, where a centralised charger is charging battery equivalent to 10 EVs. Using simulations, severity of grid current imbalance is observed, when battery charger is connected to 575-V bus. When doubly-fed induction generator (DFIG)-based wind energy conversion system (WECS) is introduced then currents and voltages are balanced but severe third harmonics of current is introduced. By replacing proportional-integral (PI) controller with adaptive neuro-fuzzy inference system (ANFIS), it's observed that voltage and current total harmonic distortion (THD) gets mitigated.
