Dynamic Modeling and Simulation of Non-Interconnected Systems under High-RES Penetration: The Madeira Island Case

Energies, 2020
The defossilization of power generation is a prerequisite goal in order to reduce greenhouse gas emissions and transit for a sustainable economy. Achieving this goal requires increasing the penetration of renewable energy sources (RESs) such as solar and

New Ancillary Service Market for ERCOT

IEEE Access, 2020
Ancillary services (AS) are the services necessary to support the transmission of electric power from generators to consumers given the obligations of control areas and transmitting utilities within those control areas to maintain reliable operations of ...

Frequency‐trajectory‐oriented control strategy for primary frequency regulation of wind farms

IET Generation, Transmission & Distribution, 2023
With the rapid increase of wind power penetration, the frequency indicators of power system, encompassing frequency deviation and rate of change of frequency (RoCoF), are prone to exceed the pertinent relay thresholds, thus leading to serious power ...

BESS Primary Frequency Control Strategies for the West Africa Power Pool

Energies, 2022
In recent years, power systems have been moving from conventional power plants toward the integration of renewable energy sources (RES). This trend is taking shape in many developing economies, including in the West Africa Power Pool (WAPP).

Amidst centralized and distributed frequency control in power systems [PDF]

, 2016
We propose a novel frequency control approach in between centralized and distributed architectures, that is a generalized continuous-time feedback control version of the dual decomposition optimization method.

Primary Frequency Response Enhancement for Future Low Inertia Power Systems Using Hybrid Control Technique

Energies, 2018
Maintaining the stability of a conventional power system during under frequency events is partially dominated by a natural behavior called inertial response.

Imbalance‐based primary frequency control for converter‐fed microgrid

IET Generation, Transmission & Distribution, 2022
Frequency droop control is a simple and effective frequency control method. However, it is not appropriate as a primary frequency control for microgrids with energy storage systems and voltage source converters (VSCs) owing to their slow response speed ...

Primary frequency control scheme for fixed-speed dish-Stirling solar-thermal power plant [PDF]

, 2017
The ability of induction generator-based dish-Stirling (DS) solar-thermal power plant in providing primary frequency control is examined. A dynamic model of the power plant is developed in which the receiver/absorber temperature of the Stirling engine is

Distributed Primary Frequency Control through Multi-Terminal HVDC Transmission Systems [PDF]

, 2015
This paper presents a decentralized controller for sharing primary AC frequency control reserves through a multi-terminal HVDC grid. By using passivity arguments, the proposed controller is shown to stabilize the closed-loop system consisting of the ...
