Abstract :
It proposes a new control algorithm to increase efficiency of a grid-connected photovoltaic power generating system. It finds a maximum efficiency point by considering the quantity of power generated from PV arrays, the number of inverters, and an efficiency of the inverter. And then it assigns the optimized power, which is in a high efficiency condition, on the PV inverter. Operational principle of the proposed maximum efficiency point tracking algorithm is given in detail. To verify the validity of the proposed method, computer-aided simulation is carried out.
