A Low-Cost Voltage Stabilization and Power Quality Enhancement Scheme for a Small Renewable Wind Energy Scheme

Abstract

This paper presents a novel voltage stabilization and power quality enhancement scheme using a PWM switched modulated power filter compensator (MPFC), which is controlled by a dynamic tri-loop (voltage, current and dynamic power signals at the load bus).The error driven tri-loop controller is used to stabilize a standalone wind driven induction generator scheme. Full voltage stabilization and power quality enhancement is validated under electric load excursions. The device is a member of a novel FACTS based compensators/modulated power filters developed by the First Author
