The Center for Electric Power and Energy at the Department of Electrical Engineering invites applications for a PhD position in Optimization, Control, and Stability of Combined AC and DC Grids under Uncertainty.
Increased integration of renewable energy sources leads to exploitation of remote sites with abundant renewable potential, as in off-shore wind farms. High voltage direct current lines are seen as the major technology option to connect off-shore wind farms to major load centers, forming HVDC grids. The off-shore grid currently in the planning phase in the North Sea belongs to one of these examples.
Advanced optimization and control algorithms under uncertainty are necessary to incorporate the advanced capabilities of a combined AC and DC grid for a large integration of renewable energy sources. The optimal operation of such a grid and the impact on the stability of both AC and DC grids, given the stochasticity of wind infeed, need to be studied in detail.
Responsibilities and tasks
The PhD student will carry out research in the field of optimization, stability assessment, and control of combined AC and HVDC grids. The work will focus on advanced computational techniques based on semidefinite programming for optimization and stability assessment. Convex relaxations will be applied to recover near-global optimal solutions. The fundamental properties of the methods and the underlying systems will be studied in detail.
Furthermore, advanced computational techniques for the stability of AC and HVDC grids will be developed, considering future low-inertia systems.
Candidates should have an MSc in engineering or a similar degree with an academic level equivalent to the MSc in Engineering.
The applicants should fulfill the following requirements:
- Knowledge of power system operation, stability, and integration of renewable electricity production
- Advanced knowledge of optimization and control, with application to power systems
- Demonstrated ability to use mathematical programming techniques based on semidefinite programming
- Knowledge of optimization tools (e.g. GAMS, MOSEK, etc.) as well as programming tools (e.g., Matlab, C++, Julia)
- Advanced skills in mathematical programming and advanced optimization techniques, e.g. linear and quadratic programming, mixed integer programming, and second order cone programming
- Good Knowledge of decision making under uncertainty and robust optimization
- Knowledge of modeling High Voltage DC lines for optimization and control
- Knowledge of simulation of power systems with large shares of distributed energy resources
- Excellent use of the English language
- Ability to present results in technical reports, and prepare scientific papers for publication in international journals
Approval and Enrolment
The scholarships for the PhD degree are subject to academic approval, and the candidates will be enrolled in one of the general degree programmes of DTU. For information about the general requirements for enrolment and the general planning of the scholarship studies, please see the DTU PhD Guide.
The assessment of the applicants will be made by Professor Pierre Pinson and Assistant Professor Spyros Chatzivasileiadis.
