A novel switched filter compensation scheme for power quality enhancement and loss reduction

The paper presents a novel FACTS-based dynamic voltage regulation and self adjusting switched filter Compensator (SFC). The SFC is controlled by a tri-loop dynamic error driven inter coupled weighted modified PID controller. SFC scheme has been fully validated for effective power quality (PQ) improvement, voltage stabilization, power factor correction and feeder losses reduction. The proposed FACTS based scheme can also be extended to distributed/dispersed renewable energy interface and utilization systems and can be easily modified for other specific stabilization, compensation requirements, voltage regulation and efficient utilization duties enhancement.
