Impact on power system transient stability of AC-line-emulation controllers of VSC-HVDC links
(Institute of Electrical and Electronics Engineers Power and Energy Society; Universidad Pontificia C (Madrid, España), 2021-07-29)
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 because they can contribute positively to the ...
Design of power system stabilizers to damp low frequency inter-area oscillations with limited information
(Institute of Electrical and Electronics Engineers Power and Energy Society; Politecnico di Milano (Milán, Italia), 2019-06-23)
This paper proposes a simplified approach to design power system stabilizers (PSSs) aimed at damping low frequency inter-area oscillations when only limited information of the power system is available. The proposed method ...
Sliding Mode Control Techniques for Voltage Source Converters under Low-Voltage Ride-Through Scenarios
(IEEE Control Systems Society (Río de Janeiro, Brasil), 2026-01-12)
The present paper evaluates different sliding mode control techniques for the negative-sequence current injection of voltage source converters under low-voltage ride-through scenarios. Under such scenarios those devices ...
Practical solutions to limit computational burden of UC in Island Power Systems
(Kadir Has Üniversitesi (Estambul, Turquía), 2024-08-08)
Unit commitment (UC) models used in real-life island power systems (IPSs) require complex modelling details and low execution times since they have to be launched repeated times for different assumptions and changing ...
Small-signal stability of type 4 wind generators as affected by the bandwidth of current and PLL controllers
(Sin editorial (Ischia, Italia), 2024-08-05)
This paper investigates the small-signal stability of type 4 wind generators as affected by the bandwidth of current and phase-locked loop (PLL) controllers. Using eigenvalue and participation factor analysis, this paper ...
Modeling demand flexibility of RES-based virtual power plants
(Institute of Electrical and Electronics Engineers Power and Energy Society (Denver, Estados Unidos de América), 2022-07-17)
In this paper, an approach to evaluate the benefits of demand flexibility for Virtual Power Plants (VPPs) is presented. The flexible demands chosen in this study are part of a renewable energy source-based VPP that ...
Economic assessment of battery energy storage systems for reducing production deviations of wind farms
(Institute of Electrical and Electronics Engineers Power and Energy Society; Technische Universiteit (La Haya, España), 2020-10-25)
Battery Energy Storage Systems (BESSs) can increase the controllability of wind farms and, therefore, the incomes its operators obtain in the energy markets. More precisely, BESSs can be used to reduce the production ...
Frequency stability boundary of small isolated power systems
(Sin editorial (Eilat, Israel), 2010-12-13)
This paper explores new frequency protection schemes based on the analysis of the ω-dω/dt (frequency - rate of change of frequency) phase plane and on the definition of frequency stability boundary in particular. Due to ...
