Background

One of the largest challenges of today’s society is how to guarantee the power and energy demand in the future in a safe, efficient and sustainable way. One of the key issues for this is to have a reliable and efficient power system at all levels. In the next coming years, we will both see a shift in electricity production consisting of more renewable sources at the same time as different forecasts predicts a significant increase in electricity use.

The research within the area is focused on studying different aspects of the power system, such as operation of microgrids, flexibility and need of energy storage, variability, reliability, control and operation of different components etc. Both the power system and different key components are studied. Moreover, the power from a renewable energy system will vary depending on the source and the system layout. The knowledge about these variations and how to plan for implementing more power from renewables is important for the function and control for the future grid.

The use of power electronics in the grid has, and will continue to, increase rapidly. Their control, reliability, efficiency and choice of material in the semiconductor is of great interest for future studies. Another important area is what to measure in the power system and to show how these measurements can be used to make the power system more efficient and reliable. Digitalization and machine learning will become two important areas in the future smart grid.

Aims

Our goals are to develop sustainable and efficient power system solutions for the grid and for the production and consumption.

Approaches

We are attempting to approach all our projects from a holistic perspective and the process ideally (when possible) includes; background analysis of the area, analytical calculations and simulations, laboratory experiments and full-scale experiments. The research within smart grid at Uppsala University is divided into several areas: power system analysis, power systems to renewable energy, implementation of renewable energy to the power system (power variability, renewable energy system modelling), electromobility and the power system, power converter topology and control, and diamond electronics.

Keywords

Power system analysis and control, renewable energy power systems, power electronics, converter topologies and control, variability analysis, renewable energy integration, reliability analysis and diagnostics, use and need of energy stroage, felexibility, electrocmobility, diamond electronics.
