Abstract

Author(s): Vikram S.Patil, Alka Thakur

This paper stresses on the voltage control technique used in CSI based grid connected PV. The process utilizes unit conversion for tracing the maximum power point and interlinking the photo voltaic array to the grid. The maximum power point is systematically interacted with a fuzzy logic controller. A proportional controller is emphasised to control the current injected into the photovoltaic grid. Simulation results presented here to validate the component models and the chosen control algorithm. Keywords: CSI, Proportional-Resonant Controller, Photovoltaic, FLC
