A Novel Control Strategy for a PV Grid Connected Voltage VAR Compensation using PI and PI Fuzzy Controller

Abstract

Three-phase grid-connected converters are widely used in renewable and electric power system applications. Traditionally, grid-connected converters are controlled with standard decoupled d-q vector control mechanisms. However, recent studies indicate that such mechanisms show limitations in their applicability to dynamic systems. This thesis investigates how to mitigate such restrictions using a Fuzzy-PI to control a grid-connected rectifier/inverter. The Fuzzy-PI implements a dynamic rule book and fuzzy rules. To enhance performance and stability under disturbance, additional strategies are adopted, including the use of integrals of error signals to the network inputs and the introduction of grid disturbance voltage to the outputs of a fuzzy system. The performance of the Fuzzy PI controller is studied under typical vector control conditions and compared against conventional vector control methods, which demonstrates that the neural vector control strategy proposed in this paper is effective. Even in dynamic and power converter switching environments, the fuzzy vector controller shows strong ability to trace rapidly changing reference commands, tolerate system disturbances, and satisfy control requirements for a faulted power system.
