Exploiting Automated Demand Response, Generation and Storage Capabilities for Hierarchical Frequency Control in Islanded Multi-Microgrids

Abstract

This paper presents a hierarchical approach to deal with the problem of frequency control in a medium voltage network comprising several microgrids and distributed generation sources operated in islanded mode. The role of automated load control and the possible contribution of local storage devices and grid-connected electrical or hybrid vehicles with onboard storage systems are some of the main developments assessed in this paper. The hierarchical approach described here proves to be capable of dealing with large numbers of distributed microsources when performing tasks related to coordinated frequency control.
