The Center for Electric Power and Energy at DTU Electrical Engineering invites applications for a double degree PhD position that focusses on development of methods for real-time assessment of oscillatory rotor-angle stability. The position is part of a joint collaboration project between DTU and NTNU titled “Smart Wide Area Monitoring and Control for Secure Operation of Systems with high Penetration of renewable energy sources”.
The PhD project will be carried out under a joint supervision with supervisors from both universities. The PhD student is required to stay for 12 months at the partner university during the PhD project.
Stable and secure power systems are of fundamental importance to modern societies and will continue to be so in the future. The global challenges to electric power systems in the coming decades are great, where focus is on energy supply with a minimal dependency on fossil fuels. The challenges involve the development of future power systems that provide stable energy supply at competitive price and with minimal environmental impact.
Power production that is a subject to prevailing weather conditions can introduce rapid changes in the system operating conditions, resulting in that planning for stable and secure operation can no longer be made a few hours ahead by offline analysis, instead there is a need for short-horizon supervision and fast planning and coordination of control actions that ensure system security.
To assure stable and secure power supply in the future renewable power systems, intelligent smart-grid solutions are needed; where methods for real-time monitoring of system security and stability margins are exploited, together with coordinated control actions, to re-establish safe operating conditions when necessary.
Previous projects at both DTU and NTNU have initiated R&D activities addressing the crucial challenges of ensuring secure operation of the future power systems. This project proposal aims to continue the technology development by extending and pushing forward the breakthroughs initiated by the previous projects and addressing other critical areas that were not covered in previous R&D.
The proposed R&D activities in the project aim to push forward the development of the technology needed for ensuring secure and stable operation of power systems having a high share of the production based on fluctuating renewable energy sources (RES) and interfaced to the transmission grid through power electronics. The focus is on development and implementation of methods for real-time stability assessment of system stability, and on development of methods to determine appropriate countermeasures.
Responsibilities and tasks
The objective is to initiate the R&D of methods capable of assessing the conditions for oscillatory small-signal stability in real-time using the element-wise approach as deployed in previous DTU research. The objective is to evaluate a stability margin, expressed in percentage loading, for which a given element (e.g. generator or a group of generators) has before the conditions of an unacceptably low damping occur.
One of the central elements in the project that facilitates strong collaboration between the involved universities is the shared exploitation of a Wide-Area Data Application (SW-platform) developed in previous R&D at DTU. This platform allows the PhD candidate to individually implement, test and validate their methods aimed to be developed in the project. Furthermore, the platform allows demonstration of combined effect of having both the real-time stability assessment methods, developed at DTU (providing awareness of the distance to critical boundaries) and the control methods finding appropriate countermeasures when critical conditions have been identified. This approach provides strong synergy between this PhD project and another PhD project that is carried out at NTNU carried out in parallel, and lays foundation for co-authored publications.
Candidates should hold a MSc in engineering or a similar degree with an academic level equivalent to the MSc in engineering.
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 Associate Professor Arne Hejde Nielsen (DTU), Senior Scientific Consultant Hjörtur Jóhannsson (DTU) and Professor Kjetil Uheln (NTNU).
