Making Aggregations Reliable: Realizability Guarantees for Battery Fleets with Heterogeneous Power and Energy Limits
Mazen Elsaadany, Mads R. Almassalkhi
Aggregated battery energy storage systems (BESS) enable large fleets of heterogeneous battery elements to participate in system-level optimization and electricity markets. Scheduli…
AC-aware Optimization Framework for Under-Frequency Load Shedding
Mazen Elsaadany, Muhammad Hamza Ali, Amritanshu Pandey +1
Under-frequency load shedding (UFLS) prevents system collapse during large disturbances. Increased penetration of distributed energy resources (DERs) and reduced system inertia mak…
Linear Aggregate Model for Realizable Dispatch of Homogeneous Energy Storage
Mazen Elsaadany, Mads R. Almassalkhi, Simon H. Tindemans
To optimize the dispatch of batteries, a model is required that can predict the state of energy (SOE) trajectory for a chosen open-loop power schedule to ensure admissibility (i.e.…
Power-Duration Characterization of Aggregated Thermostatically Controlled Loads via Reach and Hold Sets
Mazen Elsaadany, Hamid R. Ossareh, Mads R. Almassalkhi
Aggregations of thermostatically controlled loads (TCLs), such as air conditioners, offer valuable flexibility to the power grid. The aggregate power consumption of a TCL fleet can…
Optimization-based Framework for Selecting Under-frequency Load Shedding Parameters
Waheed Owonikoko, Mazen Elsaadany, Amritanshu Pandey +1
High penetration of renewable resources results in a power system with lower inertia and higher frequency sensitivity to power imbalances. Such systems are becoming increasingly su…
