Electric Energy

Head of Section: Professor Mehdi Savaghebi.

In the coming decades, there will be major changes in the way the world produces, distributes, and uses energy. Sustainability and the environment are the keywords for development. Until 2050, Denmark's entire energy system must become CO2-neutral. The energy must come from renewable energy, mainly wind and solar resources and be transmitted and stored using advanced, reliable, and efficient technologies. There is a huge potential for onshore and offshore renewable energy in Denmark. Offshore wind farms and energy islands have attracted a lot of attention in recent years which necessitates high-quality research and technology development and implementation to support such ambitious green transition goals. 

Alongside the complete electrification of Danish energy consumption, there exists tremendous potential to harness renewable energy sources and convert their power into gas, hydrogen, and biofuels. This groundbreaking concept, known as Power-to-X, envisions the seamless coupling of electricity, industry, and transportation sectors. 

We mainly work on the operation and control of smart grids and microgrids with high penetration of renewable energy resources. In this context, utilization of power electronic converters to enable state-of-the-art control, operation, protection, and energy storage technologies and to ensure high stability, reliability and power quality in power grid forms the main research focus.

Technology Implementation

We are passionate about delivering world-leading research, creating an impact for society, and want to be at the forefront of university-industry collaboration. We seek to bring new technologies to society through focus on the implementation processes within cutting-edge research, world-class teaching, and continuous industrial collaboration. Our work covers the spectrum of power system and power electronic engineering technologies with a strong foundation in research and development to support green transition and decarbonization of society in collaboration with industry. We focus on meeting the needs, challenges for implementation and operation within the industrial sector both in our research focus at the high TRL-levels and in educating talented engineers. The research of the group focuses on the implementation processes within operation and control of smart grids and microgrids, grid integration of renewable energy sources, as well as power-electronic-enabled electricity supply security and quality.
