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…
Data-driven Estimation of Under Frequency Load Shedding after Outages in Small Power Systems
Mohammad Rajabdorri, Lukas Sigrist, Enrique Lobato +2
This paper presents a data-driven methodology for estimating Under Frequency Load Shedding (UFLS) in small power systems. UFLS plays a vital role in maintaining system stability by…
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…
Unit commitment with analytical underfrequency load-shedding constraints for island power systems
Almudena Rouco, Mohammad Rajabdorri, Lukas Sigrist +2
This letter presents a corrective frequency-constrained UC (C-FCUC) for island power systems implementing analytical constraints on underfrequency load shedding (UFLS). Since UFLS…
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…
Robust Frequency Constrained UC Using Data Driven Logistic Regression for Island Power Systems
Mohammad Rajabdorri, Enrique Lobato, Lukas Sigrist
In the current practice of short-term power scheduling, online power reserves are used to address generation mismatches and contingencies. Neither online inertia nor the speed of t…
