Stay or Switch: Competitive Online Algorithms for Energy Plan Selection in Energy Markets with Retail Choice
Jianing Zhai, Sid Chi-Kin Chau, Minghua Chen
Energy markets with retail choice enable customers to switch energy plans among competitive retail suppliers. Despite the promising benefits of more affordable prices and better sa…
Combinatorial Optimization of AC Optimal Power Flow with Discrete Demands in Radial Networks
Majid Khonji, Sid Chi-Kin Chau, Khaled Elbassion
The AC Optimal power flow (OPF) problem is one of the most fundamental problems in power systems engineering. For the past decades, researchers have been relying on unproven heuris…
Approximations for Generalized Unsplittable Flow on Paths with Application to Power Systems Optimization
Areg Karapetyan, Khaled Elbassioni, Majid Khonji +1
The Unsplittable Flow on a Path (UFP) problem has garnered considerable attention as a challenging combinatorial optimization problem with notable practical implications. Steered b…
Online Algorithm for Demand Response with Inelastic Demands and Apparent Power Constraint
Areg Karapetyan, Majid Khonji, Chi-Kin Chau +1
A classical problem in power systems is to allocate in-coming (elastic or inelastic) demands without violating the operating constraints of electric networks in an online fashion.…
Complex-demand Scheduling Problem with Application in Smart Grid
Majid Khonji, Areg Karapetyan, Khaled Elbassioni +1
We consider the problem of scheduling complex-valued demands over a discretized time horizon. Given a set of users, each user is associated with a set of demands representing diffe…
