GRID TIED PV SYSTEM. A CUCKOO MPPT BASED SLIDING MODE CONTROL FOR GRID TIED PV SYSTEM

      Аннотация: A Photovoltaic system, particularly in large power scenario is usually implemented in grid interconnected mode. In order to obtain a proper synchronization between grid and PV system, it is necessity to use control algorithms. In the first case an MPPT controller is implemented to extract maximum power from the PV systems and in second stage to control the transfer of active and reactive powers from the inverter and grid to load, it is necessary to estimate reference currents by using an adaptive filtering algorithm for this estimation. Therefore, in order to achieve effective grid synchronization of PV system, a cuckoo-based grid integration control scheme is employed for the maximum power tracking control, and Instantaneous Power Theory for estimation of reference inverter current and a Sliding Mode Controller for generating appropriate inverter switching signals. This proposed system is to be implement in MATLAB/Simulink.
