PhD Position Intelligent Electrical Power Grids

Electrical power systems are changing their conventional structure which considers dispatchable synchronous generators and unpredictable load demand. The increasing share of power inverter-based resources (IBRs, such as PV, wind power, BESS), and complex demand resources (EVs, H2, datacentres, heat pumps, other converter-interfaced loads) orients system operators’ interests to the dynamic security of the power system. The Continental Europe Synchronous Area (CESA) is a large synchronous electrical grid, historically considered resilient to frequency disturbances. Nevertheless, system splits are quite severe events in which the system faces major challenges to avoid a black-out in either of the islands, as could be seen during two recent events that occurred in 2021.
As the renewable trends are only expected to continue, it is necessary to future-proof the grid for more severe frequency excursions in low-inertia situations in order to minimize the risk of cascading faults, frequency instability, and potential blackouts. Developing novel and advanced emergency load control and shedding algorithms, able to operate rapidly and effectively in low-inertia power systems and scenarios, can contribute to arresting the frequency deviation, and consequently ensuring that the system preserves the integrity and stability. The project comprises two main objectives.
The first one is to extensively study and evaluate the impact of evolving generation and demand on the frequency stability of CESA and NL grids. This will include renewable energy sources such as wind, solar, and BESS, as well as novel types of demand such as electric vehicles (EVs), heat pumps, hydrogen electrolyzers, datacentres, and other converter-integrated loads. The effect of a variety of operating scenarios of interest will be analysed, particularly focusing on large system events that may cause system disintegration, cascading faults, and blackouts. These may include large loss of synchronous and non-synchronous generation, critical transmission corridors loss or short-circuit (HVAC and HVDC), and unplanned disconnections. Furthermore, system split events will be of interest as well, as these are expected to pose the highest threat to overall CESA frequency stability.
The second objective of the project is to determine system needs and possibilities in terms of novel and advanced load control and shedding strategies in the NL and CESA grids.
Advanced algorithms are to be developed and comprehensively tested, in order to mitigate the previously-discussed challenges. The developed solutions may use advanced measurement devices available in the Netherlands (SASsensors and synchrophasors, and may also utilize real-time inertia measurement, RoCoF).
