HIGH-PERFORMANCE CONSTANT POWER GENERATION WITH FUZZY CONTROL OF GRID-CONNECTED PV SYSTEMS

Abstract

According to the paper we are improving the control technique which is developed for incremental method of the maximum power which connect with the PV systems and also fuzzy controller and it is proposed to make sure about the fast transition and smooth between the maximum power point tracking and constant power generation (CPG) which is also proposed control strategy to achieved the stable operation regarding the solar irradiance levels and high-performance. Which is used for regulate to PV output power along with the set point and it also force the PV system to operate at the left side of the MPP without any stability problem. Fuzzy controller is advance controller which is mostly suitable for the human decision making mechanism which also provided the operation of an electronic system with the expert decision. Here the fuzzy controller is compared with the another controller. By utilizing the fuzzy controller for a nonlinear system which allow the reduction for the uncertain effect in the system which control and perfectly improve the efficiency .by utilizing the simulation result we can determine the proposed CPG control in case of high accuracy, fast dynamics and stable transition.
