The Faculty of Technology, Natural Sciences and Maritime Sciences has a vacancy for a position as PhD Research Fellow in “Multiphysics-informed Digital Twins for Real-time Optimal Operation of Hydropower Units”

About the position

The Faculty of Technology, Natural Sciences and Maritime Sciences (TNM) has a vacancy for a temporary, full time position as PhD Research Fellow in “System Optimization of Grid-Services in Flexible Hydropower Units for Future Power Systems” from 1 January 2022.

The position is located at the Department of Electrical Engineering, Information Technology, and Cybernetics and reports to the Head of Department. The place of employment is Porsgrunn.

The employment period will be three years of full time with no teaching obligations, and there is a premise for employment that the PhD Research Fellow is enrolled in USN’s PhD program in Process, Energy, and Automation Engineering within three months of accession in the position.

About the PhD-project

The electricity sector is undergoing a transition toward higher shares of intermittent renewable sources. Hydropower facilities will provide new services in the new mix of sources and be a key agent to secure a sustainable energy transition. Its super-flexible abilities can be an actor for large-scale energy storage, power system stability improvements, demand-side management, and increased interconnections. In the future, increased demands for capacity, flexibility, and stability will require coordinated R&D involvement from all players in these processes (e.g., grid owners, power producers, and the supervisory authority).

The position is part of the project: System optimization between the power producer and grid owners for more efficient system services (SysOpt). In this project, Transmission and Distribution System Operators (TSO and DSOs) go together with power producers and other service providers to develop new competencies, break technology-barriers, and propose innovative methods related to voltage control. The goal is to strengthen the future power system operational security of supply and power transfer capability while reducing investment costs and transmission losses by optimizing the interplay between the power producer and grid owners through enhanced coordinated actions.

The PhD candidate will work with other PhD candidates at USN and NTNU who are covering different aspects of the same topic. The PhD candidate will also collaborate with the industrial project participants. In addition, the position will include a 12 months stay at NREL (National Renewable Energy Laboratory ) in the US. The work of this PhD study will be associated with the ongoing work on hydropower flexibility within the three USN research groups HPTD, SMART, and TMCC, in close contact with the nationally funded Centres for Environment-friendly Energy Research (FME) for the hydropower sector (HydroCen). The project aims to strengthen the overall digital competence at USN in collaboration with HydroCen in terms of control of hydropower plants. In particular, the student may focus on the following tasks.

The research for this doctoral position focuses on New technical solutions for service providers within Hydropower systems. Research questions are: To what extent is it possible to identify the optimal operation of the production facility in a highly varying electric grid system? What is the optimal hydro-design for future challenges? What is the available thermal expansion in hydrogenerators for reactive power boosting in case of extreme scenarios? How can compatible grey-box models (combining mechanistic and data-driven models) for real-time monitoring and control that depend on the online capacity of the machine, efficiency, and operational conditions costs be developed?

The work starts with initial system studies to identify the potential for improved operation. The work will create multi-physics-based FEA models of relevant synchronous machines, including different loss calculations, ventilation, and heat transfer dynamics (cooling capability). This work will further be used for developing online models (e.g., lumped parameter modeling) and inform neural networks with detailed multi-physics modeling. Emphasis should be on maximizing the utilization of the plant and lifetime while minimizing cost, and wear and tear. The work will heavily rely on a first-principle multi-physics approach rather than merely classifying huge amounts of collected data, which would lack the fundamental physics underneath. Both electromagnetic and hydrodynamics could be included as multi-physics aspects for co-simulation and evaluation at NREL labs. As a result, a strong background in engineering physics and/or Multiphysics electromagnetics simulations is a prerequisite to be successful. Further, different hydro designs will be considered for enhanced service, e.g., hybrid hydro solutions such as both converter-fed in pumping and direct grid connected machines. Moreover, a suitable (detailed) analysis of the ventilation capability is needed at different speeds of the generator. In addition, a suitable control design should be utilized for operation of hydropower plant.

The technology developments will be validated in industrial study-cases, and in the National Smartgrids Laboratory and/or Generator lab at NTNU. In addition, joint HIL (hardware-in the-loop) experiments at NREL facilities will be carried out. The work will perform a high fidelity evaluation and help reduce the technological barriers in the adoption of data-driven representations in hydropower applications for electric grid services.

The work will be communicated through regularly publish results in scientific journals and conferences and present the project to relevant national and international actors.

Qualifications

Qualifications in engineering/technology with solid knowledge within:(i) Electrical Power Engineering(ii) Electromagnetics and design of rotating machines(iii) Development of models for dynamic systems(iv) in-depth skills with FEA analysis tools such as Comsol or Ansys etc.(v) computer programming, with emphasis on languages such as MATLAB, Python, etc.
