Abstract
Electric spring (ES) is a novel smart grid technology, which is based on power electronic components. It has multitude of benefits associated with its widespread use at distribution level, which includes voltage profile enhancement, power imbalance mitigation, and power quality improvement. With the ever increasing need of incorporating intermittent renewable energy sources (RES), electric spring offers a viable solution to the problems linked with such energy sources. A new generation of electrical loads is also recently proposed, known as smart loads, which is the outcome of integrating electric spring in series with a non-critical load. This work proposes a novel control scheme for electric spring based on fuzzy logic to regulate mains voltage. Simulations are carried out for ES based on conventional PI controller, fuzzy logic controller, and adaptive fuzzy PI and their results are analytically compared.
