Voltage and Frequency Control of Self Excited Induction Generator Integrated with PV System

this paper presents a VF Controller (VFC) for self excited induction generator (SEIG) integrated with PV system at DC link feeding linear/nonlinear load. It uses a capacitor bank to excite itself and provide SEIG with reactive power support. A proposed VF controller is consist of a 4-leg insulated gate bipolar transistor (IGBT)-based current controlled voltage source converter (CC-VSC), dump load (Rd) at its DC bus and a PV system support the frequency of the system by providing active power compensation for improving quality of voltage and current under changing load conditions. Despite changes in consumer load the VFC keeps the generated V and F constant. The CC-VSC with PV system fulfills the requirement of reactive and active power of integrated system. The entire system is designed in MATLAB and its performance is analyzed under different loading conditions.
