Modeling of photovoltaic array and control of grid connected photovoltaic system to provide quality power to grid

Delivering quality power is the important issue of grid connected solar photovoltaic (PV) system. The generation of quality power from the proposed system is influenced by the intermittent nature of solar photovoltaic power, power electronic converters used and the nonlinear loads connected to the system. To understand and analyze the system an accurate modeling is required. This paper deals with modeling of PV array of 100kWp grid connected photovoltaic system in the direction of providing quality power mainly related to harmonic issues at low irradiation level. The proposed system is analyzed with the help of MATLAB/SIMULINK.
