Analysis and control of an autonomous hybrid wind-driven PM alternator and photovoltaic array without battery storage

The implementation of a feed-back controller for a voltage source inverter for obtaining constant amplitude, constant frequency supply from an integrated wind/photovoltaic system has been presented in this paper. The steady state analysis of the wind-generator has been carried out and the critical wind speed above which it will supply the load has been determined. The various operating modes of the hybrid scheme have been analyzed. The conditions in which these generators supply the load have been identified from the analysis. The inherent balance of power between the sources is demonstrated through simulation of the scheme.
