Abstract:
This paper proposes a design of grid connected photo-voltaic (PV) system through implementation of active power control & MPPT control using MATLAB/Simulink. In the present scenario of world energy sector renewable sources are growing their importance day by day. The overall system model consists of a PV array, MPPT controller, Inverter and a distribution system to deliver usable power to the end grid. However, the output of solar arrays varies due to change of solar irradiation and weather conditions. Therefore, the maximum power point tracking algorithm is implemented in DC/DC converter to enable PV arrays to operate at maximum power point. The Perturb & Observe (P&O) algorithm is employed to control the boost converter. Then the central inverter is controlled by using the PI controller for active power control, which is necessary to ensure that all maximum power is transferred to the grid. Active power control is cost effective & it improves the efficiency of the system. After the complete designing of the grid connected photovoltaic system, we analysed the performance results of the PV system in MATLAB.
