Does Central Planning Fail Locally? Evaluating EV Charging Flexibility Optimization Across Grid Levels
Ambra Van Liedekerke, Lorenzo Zapparoli, MarÃa Parajeles Herrera +3
Electric vehicles (EVs) are a key enabler of global decarbonization, and their charging flexibility is crucial for integrating high shares of renewable energy into future power sys…
Efficient Multi-Market Scheduling of Virtual Power Plants via Spectral Representation of Uncertainty
Lorenzo Zapparoli, Blazhe Gjorgiev, Giovanni Sansavini
As the penetration of distributed energy resources increases, harnessing their flexibility becomes critical for power system operations. Virtual power plants (VPPs) offer a promisi…
Risk-Aware Multi-Market Scheduling of Virtual Power Plants with Dynamic Network Tariffs
Lorenzo Zapparoli, Paul Fäth, Blazhe Gjorgiev +1
As the penetration of distributed energy resources (DERs) increases, harnessing their flexibility becomes critical for power system operations. Virtual power plants (VPPs) offer a…
A day-ahead market model for power systems: benchmarking and security implications
Andrej Stankovski, Blazhe Gjorgiev, James Ciyu Qin +1
Power system security assessments, e.g. via cascading outage models, often use operational set-points based on optimal power flow (OPF) dispatch. However, driven by cost minimizati…
Wasserstein-based Kernel Principal Component Analysis for Clustering Applications
Alfredo Oneto, Blazhe Gjorgiev, Giovanni Sansavini
Many data clustering applications must handle objects that cannot be represented as vectors. In this context, the bag-of-vectors representation describes complex objects through di…
Multi-level informed optimization via decomposed Kriging for large design problems under uncertainty
Enrico Ampellio, Blazhe Gjorgiev, Giovanni Sansavini
Engineering design involves demanding models encompassing many decision variables and uncontrollable parameters. In addition, unavoidable aleatoric and epistemic uncertainties can…
