GRID CONNECTED INVERTER SYSTEM WITH RESPONSIVE POWER CONTROLLER FOR PV APPLICATIONS

Abstract

Due to the instantaneous changing of sun oriented irradiance and temperature, it is desirable to determine the ideal voltage that ensures maximum energy yield. So as to optimize the photovoltaic energy generation, the MPPT is integrated in the inverter control. The maximum power generated by the photovoltaic system is sent to the power grid to be consumed by the nearest customers. A steady exchanging frequency is used for the current controlled inverter.
