Earlier the PV system used to offer about 10 % efficiency only due to solar intermittency, generation losses etc. But with the increasing demand of enhancing the efficiency of a PV system, its power quality is also decreasing. For the purpose of better penetration and efficiency MPPT controllers, 6 pulse inverters etc. are being implemented which leads to the presence of harmonics at output. In this paper we have considered a grid connected PV system having MPPT controller, Inverter. Analysis is made to find the optimum maximized real and reactive power by varying no. of cells in series and parallel respectively.

Abstract


Earlier the PV system used to offer about 10 % efficiency only due to solar intermittency, generation losses etc. But with the increasing demand of enhancing the efficiency of a PV system, its power quality is also decreasing. For the purpose of better penetration and efficiency MPPT controllers, 6 pulse inverters etc. are being implemented which leads to the presence of harmonics at output. In this paper we have considered a grid connected PV system having MPPT controller, Inverter. Analysis is made to find the optimum maximized real and reactive power by varying no. of cells in series and parallel respectively.
