Interaction between nuclear power plants and power electronic interfaced devices

The energy transition is common knowledge by now. Most of us are trying to reduce the carbon footprint left by humanity through electrification and fossil free electricity. This means that our power system is evolving from the traditional system consisting of large synchronous generators and passive loads, to a more complex one with production units and loads connected via converters.

The new system does not only obey the laws of physics, but also laws written by humans. The consequence? The system characteristics and dynamical response is altered, both on a global and local level. Why do we need to care? Ensuring safe and reliable operation of a nuclear power plant (NPP) demands a high level of quality in the connecting power grid in line with the nuclear safety analysis, and with the increase in complexity this quality becomes more and more challenging to maintain.

The aim of this project is thus to, from a NPP perspective, investigate the potential local risks with this co-existence of both power electronic interfaced devices and NPPs in the same, interconnected grid. Will they interact in some way? How? What would be the consequence? What actions need to be taken in order for the NPP to continue its safe and reliable operation?

Using Ringhals as a case study, these questions will be answered in the years to come.
