GRID CONNECTED HYBRID DISPERSED POWER GENERATORS BASED ON PV ARRAY AND WIND-DRIVEN INDUCTION GENERATOR

Meenakshisundaram Arutchelvi – Samuel Arul Daniel

    A grid connected hybrid scheme for residential power supply based on an integrated photo-voltaic (PV) array and a wind-driven induction generator has been proposed in this paper. This new grid-connected configuration employs a closed loop controller at the inverter interfaced to the PV array to regulate the current fed to the grid. By varying the reference current to the controller the PV array meets the reactive power needs of the induction generator (IG) and also acts as a source of real power to the grid. A dynamic mathematical model of the hybrid scheme with variables expressed in d-q synchronous reference frame has been developed. The model is implemented in the SimpowerTM platform, the simulation results bring out the usefulness of hybrid operation of PV, and wind-driven IG for grid connected operations.

Keywords: dispersed hybrid generators, current control, voltage source inverter, wind-driven induction generator, PV array
