Steady-state model for the three-leg shunt-series ac-link power flow controller
(IET (Institution of Engineering and Technology), 2015)
Shunt-series ac links constitute a class of so-called vector switching converters, capable of controlling power flows by synthesising an adjustable series voltage. A novel steady-state model for the recently introduced ...

Distributed consensus-based secondary control of multi-terminal DC railway systems
(Elsevier, 2023-06)
Electrification of the transportation sector is one of the main pillars of the future decarbonized society. In this context, high-speed railway corridors are expected to reduce as much as possible their environmental impact ...

Integrated simulation of electromechanical and thermal dynamics of voltage source converters
(Elsevier, 2024-01)
This paper proposes a simplified yet accurate enough thermal model of Voltage Source Converters (VSC), aimed at circumventing the high computational cost of existing models, which prevents their use in electromechanical ...

A holistic model-less approach for the optimal real-time control of power electronics-dominated AC microgrids
(Elsevier, 2023-04)
This paper addresses the problem of optimally operating a set of grid-forming devices in an AC microgrid when a detailed network model is not available. The main aim of the approach is to maximize the power sharing of the ...

Techno-economic optimal power rating of induction motors
(Elsevier, 2019-04)
Electric motors are valuable, long-life industrial assets, whose lifespan is often measured in decades. A period of unplanned motor downtime in an industrial plant frequently incurs an expenditure of thousands of euros per ...

Ancillary Services Market Design in Distribution Networks: Review and Identification of Barriers
(MDPI, 2020-02)
The high proliferation of converter-dominated Distributed Renewable Energy Sources (DRESs) at the distribution grid level has gradually replaced the conventional synchronous generators (SGs) of the transmission system, ...

A model-less control algorithm of DC microgrids based on feedback optimization
(Elsevier, 2022-10)
This work addresses the problem of the optimal real-time control of a DC microgrid without relying on its corresponding network model. The main goal of such a controller is to keep the nodal network voltages within the ...

Performance assessment of flexible links in distribution networks using a detailed power losses model
(IEEE Xplore, 2023)
The massive integration of distributed renewable energy resources is a reality in the current power system. In this new context with a greater volatility on the generation side it is required to incorporate new assets ...
