This paper investigates the theory of resilience and stability in multi-microgrid networks. We derive new sufficient conditions to guarantee small-signal stability of multi-microgr…
The Impact of Damping in Second-Order Dynamical Systems with Applications to Power Grid Stability
Amin Gholami, X. Andy Sun
We consider a broad class of second-order dynamical systems and study the impact of damping as a system parameter on the stability, hyperbolicity, and bifurcation in such systems.…
A Fast Certificate for Power System Small-Signal Stability
Amin Gholami, Xu Andy Sun
Swing equations are an integral part of a large class of power system dynamical models used in rotor angle stability assessment. Despite intensive studies, some fundamental propert…
Towards Resilient Operation of Multi-Microgrids: An MISOCP-Based Frequency-Constrained Approach
Amin Gholami, Xu Andy Sun
High penetration of distributed energy resources (DERs) is transforming the paradigm in power system operation. The ability to provide electricity to customers while the main grid…
