Characterization study of PV module connected to microgrid

In this paper, characterization study of 10 kW photovoltaic module is presented under various load conditions. An optimized control algorithm is used for (MPPT) conversion of photon energy to electrical energy. Control algorithm related to synchronous reference frame theory (SRFT) is used to generate gate signal for voltage source converter (VSC). PI controller is used to regulate the DC bus voltage to desired reference voltage in SRFT algorithm. The output of the PI controller generate the current required for meeting the losses. This results the desired set voltage in SRFT algorithm. The study is carried out using MATLAB Simulink version 13 under various load conditions. The study demonstrates the working of the Solar PV module connected to micro grid system for linear, nonlinear and dynamic load.
