Computational Simulation - Design & Analysis functionality of Grid Connected (GC) Photo-Voltaic (PV) System
The electrical power produced via photo-voltaic (PV) array relies largely on weather circumstances. Therefore, the PV solar grid linked inverters needs to render with regulation mechanism in order to fulfill swift response of solar irradiance changes. In this work, we presented a continuous state functionality of the PV grid-connected (GC) unit at distinct solar irradiances. The presented model is developed on MATLAB environment, which includes the PV array using an improved perturb and observe (MP&O) tracking system interconnected to DC to DC boosting conversion application, the 3-phase 3 level electric power inverter which usually associated to the utility grid using low pass filter, coupled transformer and synchronous control mechanism of PV inverter as well as , UG. The presented model is lab-created within day-by-day climate circumstances to evaluate its working functionality. The simulation results of the proposed system satisfy requirements grid performance with high power quality. In the proposed work number of cell module used 90, number of parallel string 60, maximum PV output voltage 1000wb/m2 at 274 V, minimum voltage at 600 wb/m2 at 250 V, maximum power at 1000 wb/m2-100 kw, and minimum power at 600 wb/m2-57 kw.
