A novel control strategy for microgrid voltage and frequency regulation with electronic converters

This work proposes a novel control strategy based on the output regulation theory, for achieving voltage and frequency regulation in a standalone microgrid system. The distributed generation of the microgrids includes both conventional generation types and battery energy storage systems coupled with power electronic converters. The fast-response power electronic converters play an important role for both tracking voltage and frequency set point targets and ensuring the system dynamic performance. Simulation case studies shows that the proposed control schemes can effectively track system voltage and frequency set points while mitigating the system transients under disturbances.
