Implementing General-Order Frequency Dynamic Response Model and Frequency Excursion Duration Criterion in Unit Commitment Problem
Mohammad Rajabdorri, Bo Zhou, Lukas Sigrist +1
This paper introduces a novel approach for incorporating frequency dynamics into the unit commitment (UC) problem through a general-order differential equation model, solved using…
A Comparative Study on Frequency-Constrained Unit Commitment Approaches in Island Power Systems
Miad Sarvarizadeh, Mohammad Rajabdorri, Enrique Lobato +1
The increasing penetration of renewable energy sources reduces rotating inertia and even frequency control capacity, affecting frequency stability. This challenge is significant in…
A Corrective Frequency-Constrained Unit Commitment with Data-driven Estimation of Optimal UFLS in Island Power Systems
Miad Sarvarizadeh, Lukas Sigrist, Almudena Rouco +2
This paper presents a novel corrective \gls{fcuc} formulation for island power systems by implementing data-driven constraint learning to estimate the optimal \gls{ufls}. The Tobit…
Inclusion of Frequency Nadir constraint in the Unit Commitment Problem of Small Power Systems Using Machine Learning
Mohammad Rajabdorri, Behzad Kazemtabrizi, Matthias Troffaes +2
As the intention is to reduce the amount of thermal generation and to increase the share of clean energy, power systems are increasingly becoming susceptible to frequency instabili…
Data-Driven Continuous-Time Framework for Frequency-Constrained Unit Commitment
Mohammad Rajabdorri, Enrique Lobato, Lukas Sigrist +1
The conventional approach to solving the unit commitment problem involves discrete intervals at an hourly scale, particularly when integrating frequency dynamics to formulate a fre…
