Optimal operation method for load restoration of distribution networks under disturbance scenario
Energy Reports, 2022 Extreme events can cause damages to transmission system equipment, resulting in a major power outage. In disturbance scenario, local distributed energy resources (DERs) and switches can be fully utilized to restore power loads, which is critical for ...

Polyhedral approximations of the semidefinite cone and their application [PDF]
, 2020 We develop techniques to construct a series of sparse polyhedral approximations of the semidefinite cone. Motivated by the semidefinite (SD) bases proposed by Tanaka and Yoshise (2018), we propose a simple expansion of SD bases so as to keep the sparsity
