A Distributed Scheme for Stability Assessment in Large-Scale Structure-Preserving Models via Singular Perturbation
Amin Gholami, Xu Andy Sun
Assessing small-signal stability of power systems composed of thousands of interacting generators is a computationally challenging task. To reduce the computational burden, this pa…
Stability of Multi-Microgrids: New Certificates, Distributed Control, and Braess's Paradox
Amin Gholami, Xu Andy Sun
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…
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…
