Resilient Microgrids with FACTS Technology

Abstract

Modern power systems around the world are rapidly evolving under a novel paradigm that is imposing new research and development requirements to improve their operational and topological conditions. The positioning of non-conventional renewable energies has endorsed the integration of distributed generation and with this the spread of electrical microgrids. These systems must face multiple operational challenges, which are more complex than those of traditional power systems. The development and maturity of devices based on power electronics and their connection to the electric grids make possible to improve the performance of microgrids in operational terms. In this sense, the microgrid resilience is a topic of major concern which has not been widely developed. As a result, this work aims to provide a thorough study of this issue and its close relation to flexible ac transmission systems (FACTS) technology. The paper analyses the control attributes and the applicability of FACTS technology to improve the stability and resilient operation behavior in microgrids.
