Interconnected microgrids frequency response model : an inertia-based approach
Rehimi, S.; Mirzaei, R.; Bevrani, Hassan - In: Energy reports 6 (2020) 2, pp. 179-186
Preserving the frequency stability of new important blocks in smart grids such as interconnected microgrids, is a serious challenge. Inertia can act as a significant stability/performance index for frequency regulation in the power grids. Renewable energy sources have low inertia and mostly need...
