KTH Royal Institute of Technology, School of Electrical Engineering

KTH Royal Institute of Technology in Stockholm has grown to become one of Europe’s leading technical and engineering universities, as well as a key centre of intellectual talent and innovation. We are Sweden’s largest technical research and learning institution and home to students, researchers and faculty from around the world. Our research and education covers a wide area including natural sciences and all branches of engineering, as well as architecture, industrial management, urban planning, history and philosophy.

Become a part of world-leading research and education! The School of Electrical Engineering is one of ten schools at KTH. We conduct research and education in Electrical Engineering, Systems Engineering, Information Technology, Space, Fusion and Plasma Physics. The field of electrical and electronic engineering at KTH is internationally recognized and places high in international rankings. The school is responsible for bachelor and master programs in Electrical Engineering which are closely linked to our research fields. 450 people work together in an international environment in eight departments and in the Dean’s office.

The Department of Electric Power and Energy Systems consists of about 25 faculty members, researchers and affiliated faculty who together with around 60 Ph.D. students contribute to a high professional standard of intensive work and quality results, as well as to a friendly and open environment. The work commitment is very high and the cooperative setting creates a positive sense of belonging. The staff has a multicultural background and the working language is English. The department is internationally well established, has many research collaborations with excellent partners worldwide, and is involved in several European and national projects.

PhD Program in the Digitalization of Electric Power Engineering

During 2016-2017 the School of Electrical Engineering at KTH launched a PhD program in the digitalization of electric power engineering. In connection to this effort we strive to recruit about ten PhD students to work in cross-disciplinary projects motivated by the topic of the PhD program. Common for all positions is that the PhD student will interact with both an ICT group and an Electric Power Engineering group, with corresponding supervision. The new PhD program is a considerable investment, with the goal to create new synergies between the School’s world class research in ICT and Electric Power Engineering, respectively. This will result in a unique research and education effort, where the graduated PhD’s will be highly competitive on the Swedish and international job market.

Project description

This specific position belongs to The Department of Electric Power and Energy Systems but for the project there is an established cooperation with The Department of Automatic Control. 

Project title:  Efficient Optimization Methods for hydro power operations: Model reduction.

For technical-economic simulations of the operation and investments in power systems it is common to use physical models of the system consisting of models of transmission, loads and power plants. In reality one often uses optimization models, either to maximize the profit / minimize costs for a certain actor or in order to simulate the behavior of all actors in the electricity market.

A specific challenge is hydro power. The inflow varies and is uncertain, the hydro power stations are linked to each other in the rivers, the production is a non-linear function of discharge, and there are several limitations in the operation based on legislation that limits the allowed operation space. This means that “optimal operation” of hydro power is solved with stochastic non-linear optimization.

The hydropower system consists of hundreds of power stations linked through the rivers. For efficient support tools a model reduction is needed in order to reduce the calculation time for the whole system, but it is also essential that the accuracy is still high. The fundamental challenge is to make an “optimal model reduction” where the resulting model is to be used in an optimization formulation. This is a challenging technical-mathematical area. This part has prof Lennart Söder, Electric Power and Energy Systems LAB, as main supervisor.

The PhD program in Electrical Engineering provides world class quality education, including a large list of graduate courses ensuring an in-depth development of relevant competences and skills.

KTH offers an attractive working environment, generous remuneration, as well as other employment benefits. As a PhD student at KTH you have many opportunities to participate at conferences, projects and other relevant events which will extend your professional network and benefit your future career.


The successful applicant is expected to hold or to be about to receive an MSc degree in Electrical Engineering, Engineering Physics, Applied Mathematics, Computer Science or similar.

The successful applicant should have an outstanding academic track record, and well developed analytical and problem solving skills. We are looking for a strongly motivated person, who is able to work independently. Good command of English orally and in writing is required to publish and present results at international conferences and in international journals.
