In 2017, Energinet and TenneT, the Danish and Dutch Transmission System Operators (TSOs), have announced the North Sea Wind Power Hub (NSWPH) project. The project aims at increasing by 36 GW the North Sea offshore wind capacity, with an artificial island collecting all the power produced by wind turbines and several HVDC links transmitting this power to the onshore grids. This project brings together new opportunities and new challenges, both from a technical and economic point of view. In this… 

Zero-Inertia Offshore Grids: N-1 Security and Active Power Sharing

A telecommunication-free frequency droop controller is proposed to maintain the active power balance in the offshore system and guarantee N-1 security and greater loadability of the offshore converters at pre-fault state and guarantees their safe operation in the event of any power imbalance.

Frequency Dynamics of the Northern European AC/DC Power System: A Look-Ahead Study

A novel dynamic model was developed under the phasor approximation to represent the future Northern European Power System, including High Voltage Direct Current (HVDC) links and future offshore energy islands in the North Sea, to highlight the benefit of the developed model and point out potential future frequency issues.

Closing the Loop: A Framework for Trustworthy Machine Learning in Power Systems

This work outlines key challenges (dataset generation, data pre-processing, model training, model assessment, and model embedding) associated with building trustworthy ML models which learn from physics-based simulation data and implements methods that connect different elements of the learning pipeline through feedback, thus “closing the loop” between model trainings, performance assessments, and re-training.



Master thesis : Dynamics and control of a future off-shore wind power hub

In the past decades, the increased carbon dioxide released by burning fossil fuels has been urging the demand for decarbonisation of our society. However, even if local renewable solutions are

Integrating Offshore Wind Power Via Fractional Frequency Transmission System

A novel solution to integrating offshore wind power via the fractional frequency transmission system (FFTS) is introduced in this paper. The basic idea of FFTS is to improve the technical and

Performance comparison of wind park configurations

In this report, layouts of various large-scale wind parks, both AC as well as DC, are investigated. Loss modelling of the wind park components as well as calculations of the energy capture of the

Small-Signal Stability Analysis of Offshore AC Network Having Multiple VSC-HVDC Systems

This paper presents a methodology to perform small-signal analysis of an offshore ac network, which is formed by interconnecting several offshore wind power plants. The offshore ac network is

High voltage, underwater AC cables are often used to transmit the power generated by an offshore wind farm to the main grid onshore. High charging currents in such cables require reactive

Feasibility of integrating large wind farm via fractional frequency transmission system a case study

SUMMARY The basic idea of the fractional frequency transmission system (FFTS) is to use lower frequency, e.g. 50/3 Hz, to reduce the electrical length of the AC transmission line, thus to increase

Control of Power Converters in AC Microgrids

The enabling of ac microgrids in distribution networks allows delivering distributed power and providing grid support services during regular operation of the grid, as well as powering isolated

Dynamic Equivalent of a Distribution Grid Hosting Dispersed Photovoltaic Units

This paper deals with the derivation of a simplified model of a distribution network hosting dispersed photovoltaic units. The model is aimed at short-term dynamic simulations of a transmission grid

Grid Supporting VSCs in Power Systems with Varying Inertia and Short-Circuit Capacity

A model of a grid-supporting VSC connected to a weak AC grid with low Short Circuit Capacity (SCC) and low inertia is presented and the impact of SCC and inertia is illustrated by means of small-signal stability, $H_{2}$ norm and large-disturbance analysis.
