ANFIS Controller for Voltage Compensation in Renewable Energy Applications

Abstract

this article presents the adaptive neuro fuzzy inference system (ANFIS) based controller for voltage compensation in micro grid. The micro grid has more number of voltage source converters for distribute the electric energy to the small consumers. If any kind of load change in a system has a very small impact in the output voltage of the system, which is extremely sensible. This is due to unbalanced load present in connection point, further increases this problem. In order to minimize the unbalanced load effect an ANFIS based controller has been connected with the traditional voltage source converter control circuit.here, the ANFIS controller fix the reference current gain equal to the unbalanced voltage. This reference current received from ANFIS controller is added with the voltage control loop output to fix the changed current reference for a current control loop. The proposed control logic is verified both simulation and experimentally.
