Security-constrained unit commitment (SCUC) has been extensively studied as a key
decision-making tool to determine optimal power generation schedules in the operation of …

With the increasing penetration of renewable energy sources (RES) in conventional power
systems, it has become very difficult to maintain balance between supply and demand due …

This paper proposes a coordinated regional-district operation of integrated energy system
(IES) for enhancing resilience in extreme conditions. A bi-directional flow model is …

Linear active-power-only power flow approximations are pervasive in the planning and
control of power systems. However, AC power systems are governed by a system of …

This paper presents a set of new convex quadratic relaxations for nonlinear and mixed-
integer nonlinear programs arising in power systems. The considered models are motivated …

In power system operation, transmission congestion can drastically limit more economical
generation units from being dispatched. In this paper, optimal transmission switching as a …

We introduce emerging utility-scale energy storage (eg, batteries) as part of the set of control
measures in a corrective form of the security-constrained unit commitment (SCUC) problem …

Though considerable effort has been devoted to exploiting generation-side and demand-
side operational flexibility in order to cope with uncertain renewable generations, grid-side …

The penetration of large-scale renewable energy puts an urgent demand on increasing
power grid flexibility. From the power grid perspective, transmission congestion has become …

Transmission switching (TS) has gained significant attention recently. However, barriers still
remain and must be overcome before the technology can be adopted by the industry. The …
