Are you interested in “Distributed Optimization and Control of Reactive Power considering grid stability in the Nordic Power System", and want to engage in research with skilled colleagues who share your interests?  Maybe you can become our new colleague at the Department of Electrical Engineering, IT and Cybernetics at the Faculty of Technology, Natural Sciences and Maritime Sciences (TNM). The position is available from 1 September 2026 with the latest starting date on 1 January 2027.

This is an educational position that is primarily intended to give promising researchers the opportunity to develop academically and professionally through organised research training.

It is a condition that the person who accepts the position applies for admission to the faculty’s doctoral programme in Technology within three months of starting in the position. (https://www.usn.no/english/research/postgraduate-studies-phd/our-phd-programmes/technology/)

The doctoral programme includes relevant courses corresponding to 30 ECTS (approximately six months) of study, a thesis based on independent research, active participation in national and international research environments, relevant research dissemination, a trial lecture and public defence of the thesis. Read more about organised research training at USN on our website.

The PhD research fellowship is for a fixed term of three years with pure organised research training. 

Your personnel manager will be head of department, and your supervisors will be Sambeet Mishra and Thomas Øyvang It is a prerequisite that you live close by so that you can be present at, and available to, the academic environment at your workplace during ordinary working hours. The place of work will be at campus Porsgrunn.

The position is internally funded.

About the doctoral project

The person appointed will be affiliated with the research project Enhanced Reactive Power and Voltage Coordination in the Nordic Power System (CoordQ), which is headed by University of South-Eastern Norway (USN).

The person appointed will be affiliated with the research group Electrical Power Systems. The research project focuses on strengthening the Nordic power system, from a Norwegian perspective, to meet growing electricity needs while enhancing energy security and reliability. The project will develop a national control framework to reduce power system losses, improve reactive power coordination, and stabilize grid operations by enhancing collaboration between grid controllers at different system layers. Fair price incentives and market participation for reactive power ancillary services will be established to improve grid efficiency and cost-effectiveness. CoordQ brings together leading research and industry partners including USN (project owner), NTNU, Statnett (TSO), Statkraft, Skagerak Kraft, Lede (DSO), and Aker Solutions. 

Recruitment and research education are an important part of the mission of CoordQ. The PhD candidates funded by the project will contribute with cutting-edge knowledge and research. As a CoordQ-funded PhD candidate, you will be employed by USN and take an active part in the research activities. Through the project, you will have access to a forum with other PhD candidates and postdocs, and opportunities for research to stay with partners, both nationally and abroad, through its international network.

This PhD position “Distributed Optimization and Control of Reactive Power considering grid stability in the Nordic Power System" will be associated with Work Package 1 (WP1) on Real-time Fleet Control in CoordQ. The overall objective is to strengthen multi-time scale controller coordination between Automatic Voltage Regulators (AVRs) and power electronic converters, enhancing resilience and adaptive control to improve system stability under fluctuating grid conditions.

The work of the PhD candidate will be integrated with the ongoing work carried out by the research partners in WP1. In the initial phase, the supervisors, the candidate (based on the candidate's profile), and research partners in CoordQ will work together to identify the comprehensive research questions to address the overall objective of the PhD work.

Some potential specific research objectives:

• Develop distributed optimization strategies for optimal reactive power dispatch in the Nordic Power System
• Design Automatic Voltage Regulation schemes under various operational conditions including transformer limits, generator set points and stability
• Investigate limits for load cycles and inductive absorption in varied grid topologies
• Explore dynamic controller limits between synchronous generator and inverter-based resources for grid balancing
