The ongoing energy transition means replacing fossil fuel with renewable energy. Electrical energy is the major player in this and takes a more and more important role in society. It is therefore important to complement energy and climate-related targets with the assurance of reliable electricity supply. The power system research at IEA is aligned with these high level goals and key themes are:

• Grid capacity for the energy transition covers integration of wind power and solar electricity on distribution and system levels, but also electricity supply of fast chargers and electric roads that are central to the electrification of road transports.
• Reliable power supply includes assuring personal safety through reliable fault clearing and managing stability limits. Analyzing large disturbances including geomagnetic disturbances is also included together with the important power system restoration after a blackout with blackstart and island operation.

The research methods range from experimental analysis of laboratory-scale systems to computer simulations of detailed dynamic models of national power systems. This is complemented by field measurements from Phasor Measurements Units and other devices. The subject areas covered cover but are not limited to power systems analysis, electrical machines, power electronics, signal processing and power system automation.
