Mitigating Regional Traffic Congestion via School Start Time Scheduling: A Bilevel Alternating Optimization Approach
Antonios Georgantas, Stelios Timotheou, Christos G. Panayiotou
This paper addresses morning commute congestion caused by concentrated school-related trips in urban networks. We propose a bi-level optimization framework for regulating school st…
Stability of vehicular admission control schemes in urban traffic networks under modelling uncertainty
Michalis Ramp, Andreas Kasis, Stelios Timotheou
Urban transportation networks face significant challenges due to traffic congestion, leading to adverse environmental and socioeconomic impacts. Vehicular admission control (VAC) s…
Energy Consumption Optimization for Autonomous Vehicles via Positive Control Input Minimization
Andreas Hadjigeorgiou, Stelios Timotheou
Autonomous vehicles (AVs) present a unique opportunity to improve the sustainability of transportation systems by adopting eco-driving strategies that reduce energy consumption and…
On the stability properties of power networks with time-varying inertia
Andreas Kasis, Stelios Timotheou, Marios Polycarpou
A major transition in modern power systems is the replacement of conventional generation units with renewable sources of energy. The latter results in lower rotational inertia whic…
A Hierarchical Robust Control Strategy for Decentralized Signal-Free Intersection Management
Xiao Pan, Boli Chen, Li Dai +2
The development of connected and automated vehicles is the key to improving urban mobility safety and efficiency. This paper focuses on cooperative vehicle management at a signal-f…
Demand Management for Peak to Average Ratio Minimization via Intraday Block Pricing
Carolina Cortez, Andreas Kasis, Dimitrios Papadaskalopoulos +1
Price based demand response schemes may significantly improve power system efficiency. Additionally, it is desired that such schemes yield improved power operation, by reducing the…
Privacy of distributed optimality schemes in power networks
Andreas Kasis, Kanwal Khan, Marios M. Polycarpou +1
The increasing participation of local generation and controllable demand units within the power network motivates the use of distributed schemes for their control. Simultaneously,…
Optimal secondary frequency regulation with on-off loads in power networks
Andreas Kasis, Stelios Timotheou, Marios Polycarpou
Load side participation can provide support to the power network by appropriately adapting the demand when required. In addition, it enables an economically improved power allocati…
Optimal intervention strategies to mitigate the COVID-19 pandemic effects
Andreas Kasis, Stelios Timotheou, Nima Monshizadeh +1
Governments across the world are currently facing the task of selecting suitable intervention strategies to cope with the effects of the COVID-19 pandemic. This is a highly challen…
