Analysis and Design of a Nonlinear Fuzzy Controller Applied to a VSC to Control the Active and Reactive Power Flow

The voltage source converters VSC's are converters highly used in systems of distributed generation, HVDC's and motor drivers, thanks to the feasibility and facility to control the active and reactive power independently, in a fast and effective way. In this paper the performance of a VSC in its dynamic and steady state behavior is analyzed, where a model is validated in certain operation range and particular conditions; in addition a nonlinear fuzzy control was proposed for controlling independently the active and reactive power flow, between a VSC and an active load, with excellent results.
