Hierarchical Frequency Control Scheme for Islanded Multi-Microgrids Operation

Abstract

This paper presents a new hierarchical approach to deal with the problem of controlling frequency and active power generation of a medium voltage network comprising several microgrids and distributed generation sources operated in islanded mode. The hierarchical approach described here should be cost effec-tive and capable of dealing with large numbers of distributed microsources and performing tasks related to coordinated fre-quency control.
