Abstract : Solar Power is a sustainable renewable energy source which does not produce environmental pollution like conventional sources. The solar PV power can be transferred to grid using single stage Voltage Source Inverter (VSI) topology. Maximum Power Point Tracker (MPPT) will force the PV system to operate at the maximum power condition. Here MPPT will generate a power angle with which the VSC output voltage leads the grid voltage. The nonlinear nature of VSI is removed by an Input-Output Feedbck Linearization Controller (IOFL). The IOFL controller development includes the complete linearization of the VSI and linearized system is controlled with a linear controller. So, in this paper, Power angle control technique is incorporated along with IOFL controller so that active power flow can guided from solar panel to grid. The proposed method is more meaningful when the synchronization of grid voltage with the controller is also a part of it. So a Phase Locked Loop is also discussed for connecting it in the controller side. This paper focused on a simple, convenient method of solar power control to grid with the inclusion of MPPT, IOFL, PLL and power angle control. The simulation results shows the effectiveness of the controller in power transfer capability of grid connected PV system.
