High performance single-stage photovoltaic system interfacing grid without any MPPT algorithm

Anew control strategy to achieve high performance from solar photovoltaic system using single stage inverter interfacing grid without maximum power point tracking (MPPT) techniques is investigated in this paper. Sinusoid-tracking algorithm and adaptive filter is proposed to improve the power quality and to regulate constant AC voltage at the point of common coupling (PCC). Proportional integral controllers for the both outer loops are reinforced by antiwindup strategy to prevent saturation issue when system is subjected to sudden variation. The effectiveness of the developed control algorithm and the proposed configuration are tested using Matlab/Simulink.
