EM-SS model of high-speed generators in Microgrids

An Electromagnetic-State Space, EM-SS, modeling approach is presented and used for performance prediction of high-speed synchronous generators during out of phase operation in Microgrids. This mode of operation may result in stresses on the network or the failure of the high-speed generators. The modeling approach is suitable for Microgrids consisting of multiple high-speed generators feeding three phase AC and DC load systems as connected to the main grid or during islanding mode of operation. The approach is validated, by comparing simulation results to test data, in a case study of a Microgrid with two out of phase high-speed generators.
