Dynamic Flexibility Requests in Local Flexibility Markets: Quantifying the DSO Willingness to Pay
Savvas Panagi, Chrysovalantis Spanias, Petros Aristidou
Local Flexibility Markets (LFMs) require Distribution System Operators (DSOs) to determine both the quantity of flexibility to procure and the corresponding willingness to pay duri…
A Benchmarking Case Study for Local Flexibility Markets: Network, Scenarios, and Open Inputs
Savvas Panagi, Chrysovalantis Spanias, Petros Aristidou
External inputs to local flexibility markets, network models, demand scenarios, flexibility offers, and asset thermal, economic parameters do not change the clearing methodology, y…
Enhanced Optimal Power Flow Using a Trained Neural Network Surrogate for Distribution Grid Constraints
Savvas Panagi, Chrysovalantis Spanias, Petros Aristidou
The growing penetration of distributed energy resources (DERs), electric vehicles (EVs), and heat pumps (HPs) in distribution networks underscores the need for secure, computationa…
Physics-Informed Neural Network Models for EMT Simulators
Ignasi Ventura Nadal, Mohammad Kazem Bakhshizadeh, Petros Aristidou +4
This is the first paper, to the best of our knowledge, to propose a framework that integrates Physics-Informed Neural Network (PINN) models in Electromagnetic Transient (EMT) simul…
A Thermal-Electrical Co-Optimization Framework for Active Distribution Grids with Electric Vehicles and Heat Pumps
Savvas Panagi, Chrysovalantis Spanias, Petros Aristidou
The growing electrification of transportation and heating through Electric Vehicles (EVs) and Heat Pumps (HPs) introduces both flexibility and complexity to Active Distribution Net…
Conversations with Data: How Data Journalism Affects Online Comments in the New York Times
Avner Kantor, Sheizaf Rafaeli
Users in the data age have access to more data than ever before, but little is known how they interact with it. Using transparency and multimedia, data journalism (DJ) lets users e…
