Thesis - Inverter Control Strategies for Power Quality Enhancement: A Hardware-in-the-Loop Simulation Study
2 weeks ago
We have been electrifying industries, powering homes and transforming life through innovation and collaboration for more than 100 years. Empowered by our goal, we are determined to enable fossil free living. To succeed we, as one of Europe's leading energy companies, must be fossil-free ourselves.
But that’s not enough. That’s why we are looking beyond our own industry, to see where we can really make a difference.
Join us in our journey towards a fossil freedom.
Power Climate Smarter living - that’s our purpose. We are looking for the brightest students to make this happen. Together you will contribute to a fossil free future. You will have a unique position to contribute to our purpose. All we ask from you is to use your Superpowers and share your energy to help us achieve our goal.
Job DescriptionAre you eager to drive innovation to integrate more renewable energy in the electrical grid? If yes, join us to shape the future of power quality
Intermittent power generation, mainly from wind and solar power, constitutes an increasing share of Swedish electricity production. However, distributed generation, such as PV (Photovoltaics) installed in low-voltage networks, introduces new challenges for maintaining good power quality. A larger share of PV together with EV (Electric Vehicle) charging increases the range of situations where the voltage quality is challenged, from scenarios of high producing costumers (prosumers) to high consuming costumers. If we cannot solve this challenge, this means we cannot connect more DERs to the grid.
Controlling PV inverters presents a promising opportunity to address these challenges. By implementing control strategies for these inverters, it is possible to improve the voltage quality. To explore this potential, inverters and control strategies are to be evaluated using a hardware-in-the-loop testbed. Modeling of networks and control systems are done in MATLAB Simulink or a similar environment.
The purpose of the thesis is to investigate inverters’ response to control strategies, how they can improve the power quality of the low-voltage network, evaluating the potential using software and hardware.
The thesis will be conducted at Vattenfall R&D in the Distribution portfolio as a part of the “Local Grid Control” program. The program aims to build expertise in new solutions for the local grid and how these can provide the greatest benefit.
