A Brief Review on Electric Spring: Analysis, Control and Applications

Abstract

The current energy scenario in the world considering the overconsumption of fossil fuels as well as its disastrous impact on environment calls for the promotion of renewable resources to take part in the growth towards sustainable development. With the penetration of such intermittent renewable energy sources into the existing grid, it not only enhanced the capability of the grid but also posed challenges regarding system stability. A practical solution to these problems by means of a new technological concept called “electric springs” is presented in this paper which enhances the system stability and provides voltage regulation for the same. Reviewing the various analyses, control methodologies as well as applications regarding the electric spring provides the confidence to further analyze its scope in large-scale power distribution system.
