Techno-economic viability of variable-speed pumped-storage hydropower based on centrifugal pumps used as turbines
Thomas Mercier

This research takes place in the frame of SmartWater, a 3.5-year research project funded by the Walloon region, Belgium, and whose goal is to investigate the conversion of former mines and quarries into pumped-storage hydropower (PSH) sites, taking advantage of existing cavities. The project involves several academic and industrial partners, among which Laborelec, Electrabel and Cofely, as well as sponsors, including Ores, Elia, Charmeuse and Ensival-Moret. The SmartWater project is divided in several work packages, ranging from the geological study of potential mines and quarries, to the economical and electromechanical aspects of pumped-storage hydropower.

Stability performance analysis and control of islanded microgrids
Guy Wanlongo Ndiwulu

Nowadays the discussions about electric energy systems are generally focused on the system reliability and valorisation of renewable energies. Thereby, several means are investigated in order to achieve its goals, among which we have microgrids. These latter are considered as electrical subsystems with distributed energy generators, energy storage devices and loads, able to operate with connection to the main grid or in islanded mode. This electrical system technology is very different compared to the conventional power systems. Because the interfaced power converters based distributed sources characterize them. This is making the microgrid controllability and stability depending of power converters.
The main contribution of this project is to propose a control strategy able to maintain the voltage amplitude and frequency in the allowable range in the cases of islanded microgrids fed by miscellaneous micro-sources (photovoltaic, small hydropower and diesel generator) and energy storage devices such as batteries. The developed control strategy is tested with Matlab/Simulink.

Adequacy assessment of the belgian power system with the integration of electro-fuels
Aurélia Hernandez

The main goal of the project BEST is to study the contribution of synthetic and electro-fuels to the Belgian energy system.

With the decentralization of the energy production and storage, it can be expected that future power system will consist of big producers, big consumers, and quasi-autonomous areas representing the distribution grids. These latter are named in such a way because from the transmission network point of view, they are no longer seen as passive loads, but mainly neutral and now and then pulling or injecting power.

From this, it can be stated that the contribution of synthetic and electro-fuels will be studied on a future power system composed as mentioned previously by big consumers, big producers and quasi autonomous areas representing the distribution grid.

This PhD focuses on the power electric system part and more precisely on the adequacy assessment of future power systems where electro-fuels will be integrated.

“Adequacy is a way of measuring weather a power system meets the expected supply requirements of electrical energy at a certain point in time.”

Control of grid connected medium voltage DC micro-grids
Eduardo Rene Vasquez Mayen

Micro-grids allow the connection of renewable energies while being able to compensate for the variation in generation and thus avoid disrupting the end user or the main grid. Using DC voltage instead of AC proposes several advantages for micro-grids as less conversion losses can lead to a higher efficiency. The stability and control of mid voltage micro-grids is studied as their implementation and standardization is still in development.

Stability study of a grid using only renewable energies leading to an exclusive use of power electronics in the system
Quentin Delhaye

In this thesis, a dynamic study is carried out on a PEDS (Power Electronics Dominated System) due to the penetration of renewable energies. Indeed, due to the strong penetration of renewable sources, this leads to a lower inertia of the system. Stability is therefore threatened.
The studied electrical system is based on 100% renewable sources.
Initially, the modeling of electronic power converters will be done. Then, a stability study can be made on the basis of the modeling (for example stability criterion). Finally, the system will be simulated to illustrate the mathematical results found.

Erzen Muharemi

Providing a better understanding of typical converters (MPPT, Inverter/rectifier topologies, control structures) and finally creating accurate models of grid-tied converters. The research is done with the purpose of supraharmonics understanding.
