Design and Analysis of Grid-Connected Pv Systems With Generation Of Constant Power

Abstract

In this paper an improved  control strategy  is implemented the incremental method of the maximum  power which is feed to the  PV systems and it is proposed to make sure about the  smooth and fast transition between  Constant Power Generation (CPG) and maximum power point tracking ,and also  by  the proposed control strategy we can  always achieved the  stable operation, Regardless of the solar irradiance levels and high-performance. Therefore fuzzy controller is also implemented in this project, because fuzzy controller work like a human decision-making mechanism, providing the operation of an electronic system with decisions of experts.and this fuzzy control is compared with the other controller. Which  can  be  regulate  by the PV output power according to any set-point, and it also force the PV systems to operate at the left side of the maximum power point without  any stability problems. Simulation results have been  verified  in the effectiveness  manner by  using the proposed CPG control in terms of high accuracy, stable transitions , and  fast dynamics.
