Sinusoidality Index
J. Gutiérrez Florensa, L. Sigrist, Á. Ortega +1
Maintaining sinusoidal or near-sinusoidal operating conditions in electrical systems is essential, as is their accurate assessment. This letter proposes a novel metric, namely the…
Theoretical and Experimental Limitations of RoCoF Estimation
Gutierrez-Florensa, F. Sanniti, D. Tedeschi +3
A precise estimation of the Rate of Change of Frequency (RoCoF) is crucial for secure power system operation. In fact, RoCoF is strictly related to the amount of the available phys…
Enhancing Robust Multi-Market Participation of Renewable-Based VPPs through Flexible Resources
Hadi Nemati, Álvaro Ortega, Pedro Sánchez-Martín +3
In the transition toward a sustainable power system, renewable-based Virtual Power Plants (RVPPs) have emerged as a promising solution to the challenges of integrating renewable en…
Integration of Concentrated Solar Power Plants in Renewable-Only VPP with Electrical and Thermal Demands: A Two-Stage Robust Bidding Approach
Hadi Nemati, Pedro Sánchez-Martín, Álvaro Ortega +2
This paper proposes the integration of Concentrated Solar Power Plant (CSP) in the Renewable-only virtual power plant (RVPP) for bidding in the electricity day-ahead and secondary…
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…
