Background and activities
Discipline / Work Area
The LowEmission Research Centre is developping new technologies and concepts for offshore energy systems, energy efficiency and integration with renewable power production technologies for application on the Norwegian Continental Shelf.
The aim of my PhD is to investigate and propose new control strategies for guaranteeing the stability in oil and gas platforms with significant renewable energy integration. Within this framework, the following research questions arise:
- The electrical grid of an oil and gas platform is considerably larger than a microgrid but still much smaller than a country-wide power system. How can the emerging techniques for the analysis of the stability of microgrids and the ones for large grids dominated by solar and wind be applied to this specific platform scenario?
- Will the analysis of the stability of an oil and gas platform with significant contribution of wind energy demand a hybrid approach combining different aspects of microgrids and large grids?
- Which are the root causes of instabilities in a platform's electrical grid with significant contribution of renewables?
- Is it possible to properly discern rotor angle, voltage, frequency, and harmonic instabilities? Which tools are appropriate for analysis and assessment of each type of instability?
- Which cooperative strategies for energy storage, virtual inertia, flexible loads, and multifunctional inverters can be explored for avoiding or mitigating instabilities?
- How to investigate the causes for instabilities and assess the applicable mitigating strategies with the help of practical experiments performed at the National Smart Grid Laboratory (hosted by the Faculty of Information Technology and Electrical Engineering in cooperation with other NTNU faculties)?
