Dynamics and Control of Microgrids as a Resiliency Source

Journal Article · · International Transactions on Electrical Energy Systems

Microgrids can be operated in a utility-connected mode with the neighboring distribution system or in an islanded mode in separation with the distribution system. As the major disasters occur more and more often, islanded microgrid is proposed as a possible solution to serve essential loads until the utility service is restored. This paper evaluates the feasibility of using microgrids as a resiliency resource by a field test. A control scheme, integrating droop control and feedback control, is applied on a modified IEEE 13-node test feeders. The simulation results validate the proposed control scheme and the transient stability
