DFIG, THD, PV, RSC, GSCAbstract
A wind-solar hybrid system using Doubly Fed Induction Generator (DFIG) is proposed. In this proposal, we
will implement a rotor current control strategy. Over the entire period of operation, a solar photovoltaic (PV) unit of
appropriate capacity has been augmented with the rotor circuit of the DFIG. A marginal battery backup is also included
to supplement the rotor power in order to maintain continuity of power generation. The quality of power and the
efficiency can be improved and maintained, as both the solar PV and wind energy complement each other during lean
periods of either source. The proposed scheme will be validated in simulation using MATLAB-Simulink which can
produce the desired results.
