Would you like to become part of the solution toward green energy transition, by helping develop the methods for modeling renewable power plants and future energy systems? 

The Renewable Plants in Energy Systems (RES) section at DTU Wind and Energy Systems is inviting candidates to apply for a PhD in “Power System Black Start Services from Utility-Scale Hybrid Power Plants”. The research in this section is multidisciplinary, and you will enjoy the advantages of a creative and inspiring work environment. You will get the opportunity to participate and influence the development of advanced renewable power plants in collaboration with top universities and industry in the field of wind energy research in Europe and globally. 

We offer a rewarding and challenging job in an international environment. We strive for academic excellence in an environment characterized by collegial respect and academic freedom tempered by responsibility. We develop talent by offering national/European and global networking opportunities, unique research infrastructure including a fully controllable MW-scale hybrid power plant at our campus, and a collaborative research environment.

Job profile
This PhD scholarship is fully funded through a recently awarded European Doctoral Network (DN) project funded by the European Union’s Horizon 2020 Marie Skłodowska-Curie Actions programme. DN programme provides training through doctoral research to talented early-stage researchers. The researchers, in this project called WindConnect, will enroll in PhD programmes and be employed for 36 months within a network of universities and industry partners addressing the design, modelling, control, and techno-economic optimization of wind turbines, wind farms, and hybrid power plants (HPPs). Through this program, 15 Researchers will receive cutting-edge technical, entrepreneurial and soft-skill training, benefiting from industrial secondments, co-supervision, and access to a robust network of industrial partners and advanced experimental facilities.  These efforts empower the next generation of highly skilled researchers and engineers to drive technological innovation, enhance energy security, reinforce Europe’s leadership in green energy technologies, support the transition to a sustainable, decarbonized energy future, and help meet climate targets.

Candidates must meet the following eligibility criteria for researcher recruitment:
They must not already hold a doctoral degree at the time of recruitment and should have less than four years of full-time research experience following the degree that qualifies them for PhD studies. Additionally, candidates must not have resided or carried out their main activity (work or studies) in Denmark for more than 12 months within the 36 months immediately preceding the recruitment date.

Project background
Hybrid power plants (HPPs), combining wind, solar, and energy storage behind a single grid connection, are gaining traction for their potential to increase energy yield and profitability. With multiple converters and technologies, HPPs offer enhanced capabilities for advanced grid services. However, control and coordination across diverse assets remain a major challenge, especially for emerging services like black start. Research in this area is still in its early stages, presenting exciting opportunities for innovation.

As conventional fossil-fuel generators are phased out, converter-connected renewable sources like wind power must take on critical power system services such as black start and system restoration. While black start capabilities from individual renewable plants are being explored, research on HPPs in this context is nearly absent. Delivering black start from HPPs requires coordinated control across diverse technologies and storage systems, with careful management of stability, transient behavior, and system stress. Control modes must adapt across different phases of black start, while accounting for uncertain renewable resource availability and interoperability across multiple control layers.

To address this, the objective of this project is to develop a black start strategy for hybrid power plants (HPPs), focusing on control, protection, and system stability. It will model a utility-scale HPP that includes an offshore wind power plant, an onshore solar power plant, and onshore energy storage systems, all relevant for black start studies. The project will develop electromagnetic transient (EMT), root mean square (RMS), and statistical models to support control and stability analysis for black start service provision.

As part of the WindConnect research consortium you will interact with researchers and experts across the network. This requires strong collaboration and communication skills, enabling you to contribute to the ambitious goals of the project. You will also have the opportunity to cooperate with leading European research institutes and are expected to undertake external research stays of approximately 6–9 months at other partners within the consortium.

Responsibilities and qualifications
During your PhD studies, you will model and develop advanced operational strategies needed for an HPP for a reliable black start.

You are expected to identify the potential of utility-scale, multi-technology HPPs to provide black start services. It will model an HPP combining offshore wind, onshore solar, and energy storage systems, tailored for black start studies. A comprehensive black start strategy will be developed, addressing control coordination, technology interaction, and controller stability to support system restoration. Finally, the project will quantify the added value of black start services from HPPs compared to single-technology renewable plants, emphasizing improved availability and reliability.

As part of your PhD studies, you will publish your work in reputed journals and present it at peer-reviewed scientific conferences. A detailed project plan will be developed with the supervisors within the first two months after enrollment.

You will also play important supporting role in the deliverables of IEA Wind Task 50 on Hybrid Power Plants.

You will also need to assist in the co-supervision of MSc theses and provide teaching assistance in courses taught at DTU for a limited number of hours. 

The successful candidate fulfills the following requirements: 

• MSc degree in power system engineering, electrical engineering, control systems or closely related fields.
• Strong foundation in converter control, power system dynamics, and control theory
• Experience with modeling and simulation tools such as PSCAD, MATLAB/Simulink, DIgSILENT PowerFactory, or similar.
• Familiarity with EMT and RMS modeling approaches.
• Understanding of converter-based generation systems (wind, solar, storage).
• Knowledge of grid services, especially black start and system restoration.
• Strong analytical skills and ability to conduct independent theoretical and applied research.
• Proficient skills (written and verbal) in English and ability to work across disciplines and cultures.

The successful candidate must also fulfill the requirements for admission to a PhD program at DTU.

You must have a two-year master's degree (120 ECTS points) or a similar degree with an academic level equivalent to a two-year master's degree.
