Impact of current limiters and fast voltage boosters in grid-forming VSC-based generators on transient stability
Régulo E. Ávila-Martínez, Javier Renedo, Luis Rouco +4
Transient stability is a complex phenomenon presented in multi-machine and multi-converter systems, and it is still considered a key limiting factor for stressed power systems. The…
Flexible Robust Optimal Bidding of Renewable Virtual Power Plants in Sequential Markets
Hadi Nemati, Pedro Sánchez-Martín, Álvaro Ortega +3
In this paper, a novel approach to define the optimal bidding of renewable-only virtual power plants (RVPPs) in the day-ahead, secondary reserve, and intra-day markets is proposed.…
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…
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…
Coordinated control in multi-terminal VSC-HVDC systems to improve transient stability: Impact on electromechanical-oscillation damping
Javier Renedo, Luis Rouco, Aurelio Garcia-Cerrada +1
Multi-terminal high-voltage Direct Current technology based on Voltage-Source Converter stations (VSC-MTDC) is expected to be one of the most important contributors to the future o…
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…
Optimal Participation of Heterogeneous, RES-based Virtual Power Plants in Energy Markets
Oluwaseun Oladimeji, Alvaro Ortega, Lukas Sigrist +3
In this work, we present a detailed model of a Renewable Energy Source (RES)-based Virtual Power Plant (VPP) that participates in Day-Ahead Market (DAM) and Intra-Day Market (IDM)…
Dynamic Virtual Power Plant: A New Concept for Grid Integration of Renewable Energy Sources
B. Marinescu, O. Gomis-Bellmunt, F. Dörfler +2
The notion of Virtual Power Plant (VPP) has been used many times in last years in power systems and for several reasons. As a general trend, the behavior of a classic synchronous g…
Fast voltage boosters to improve transient stability of power systems with 100% of grid-forming VSC-based generation
Régulo E. Ávila-Martínez, Javier Renedo, Luis Rouco +4
Grid-forming voltage source converter (GF-VSC) has been identified as the key technology for the operation of future converter-dominated power systems. Among many other issues, tra…
Impact on power system transient stability of AC-line-emulation controllers of VSC-HVDC links
Javier Renedo, Lukas Sigrist, Luis Rouco +1
High voltage direct current links based on voltage source converters (VSC-HVDC) embedded in alternating current (AC) systems are receiving a great deal of attention recently becaus…
