Improvement of power factor and voltage for renewable energy systems using PLC's new fuzzy module

This work presents a novel control scheme using an industrial programmable logic controller (PLC) with a new fuzzy module to enhance the power factor and voltage of a hybrid wind/PV power generation system. The proposed scheme can automatically regulate both the power factor and voltage of a wind induction generator under various wind speeds. From the experimental results, it shows that the proposed control scheme can effectively provide better power factor and voltage profile for the studied renewable energy system.
