Power System Specialist for transient analyses

Do you want to be part of developing Denmark's future high-voltage electricity transmission network, where extensive investments over the next many years are required for the green transition?

As a Power system specialist in our Electrical Analysis department, you will have the opportunity to apply your solid knowledge of power systems, while also having the opportunity to directly influence the future Danish electricity network during both the analysis and project phases. Your new place of work will be at our office in either Fredericia or Ballerup.

You will be part of an organization, where flexibility and work-life balance are high on the agenda, and you will therefore be offered IT equipment for a good home office setup, for you to vary in the best possible way between being at our office or at home. 

Become a specialist in transient studies

You will be part of a well-established department consisting of 13 skilled colleagues, who are jointly responsible for insulation coordination, reactive power compensation and power quality in relation to the design of future electricity transmission network projects, including connection of renewable electricity and major consumers such as PtX plants. The department has a primary role in solving the technical challenges related to the transition from overhead lines to underground cables, and the transition to a power system consisting of converter-based production and consumption units, as well as new HVDC connections.

This leads to new and exciting projects e.g.:

• We are at the forefront of developing detailed EMT models and innovative methods to enhance power system resiliency. Our focus is on ensuring the adequacy of protection devices against transient overvoltage’s, utilizing advanced simulation tools like PSCAD to model and analyse equipment insulation under various stress-conditions.

• Our EMT design studies are crucial in integrating solar, wind and PtX substations. These studies enable engineers to design robust and efficient substation infrastructures by thoroughly analyzing the transient behavior and response of electrical system

• With the widespread adoption of HVDC technology, especially multiterminal HVDC and energy island projects, it requires effective insulation coordination design to ensure equipment safety and reliability while also keeping the cost low.

To succeed in this job, it is important you have knowledge of EMT phenomena and how to identify and investigate these. In addition, you are able to apply specific mitigating solutions, such as designing surge arresters or specific switching strategies. It can be advantageous, but not a necessity, if you have knowledge of power quality, including harmonic propagation and distortion.

You can look forward to an exciting position at a high professional level, with technical responsibility for conducting insulation coordination studies. You will be part of a professional environment, where you can immerse yourself in advanced analysis methods and models for the entire Danish transmission network.

The tasks are therefore specialized and may include the following:

• EMT modelling in PSCAD using grid equivalents with network reduction in PowerFactory and subsequent verification of models.
• Modelling underground cables and overhead lines based on geometric data and specifications from manufacturers.
• Performing switching transient studies, transient recovery voltage studies, temporary overvoltage studies, and lightning studies for AC systems in PSCAD.
• Performing insulation coordination study for HVDC systems, including transient overvoltage study, grounding resistor sizing to avoid zero-miss, AC breaker requirement study, etc.

Analytical profile with a collaborative approach

Ideally, you have a master's degree or PhD. specializing in power systems, or you can demonstrate you have acquired similar competencies in other ways, e.g. through specific experience with insulation coordination studies. It is also a valuable asset if you have experience with EMT analyses in PSCAD and experience with PowerFactory.

We are open to both experienced and newly graduated candidates, since we have a variety of assignments with different complexity. You are able to further develop and optimize the scripts, processes and guidelines used in the department. You are highly proficient in both spoken and written English, as you will collaborate with both internal and external specialists, colleagues from other TSOs and universities as part of your daily work.

On a personal level, you have a good sense of analysis and a systematic approach to your tasks. You work effectively and you adapt easily to new and varied activities. You are team-oriented and cooperative with the abilities to both share knowledge at a high technical level as well as communicate in a clear and concise manner with people having a different or non-technical background.

Application and contact details

Please send your application with a CV and other relevant appendices, via the link 'Send application', no later than 5 November 2024. 1st Interviews are expected to be conducted in week 46, and 2nd interviews on 20 November in Fredericia.

If you have any questions about the job, please feel free to contact head of department Jacob Michael Jørgensen on +45 6124 3348.

We see diversity as a strength and encourage all qualified people, regardless of background, to apply for the job. We work actively and determinedly with diversity in Energinet and therefore encourage you to exclude information about age, marital status, etc. to minimise outage biases in the process. You can read more about our diversity policy here.

Energinet Eltransmission A/S is responsible for developing, building, owning and operating the necessary electricity transmission grid and making it available to the transmission system operator (TSO) with the right capacity and at the correct quality as cost-efficiently as possible, ensuring optimal and safe utilisation of the installations. We ensure optimal asset management by focusing on the installations' overall service life - from cradle to grave. We are a subsidiary of the Energinet Group, which represents societal interests when supplying Denmark with electricity and gas and that the energy system is converted to green energy. Our culture is closely linked to our social responsibility, and we work actively with the UN's global goals on sustainable energy, climate action, partnerships for action as well as industry, innovation, and infrastructure. By leading the way in the green transition, we can help to solve the global climate challenge. New solutions require us to be able to see problems from many different angles, and diversity is therefore a keyword in our culture. We strive to listen to, involve and share our knowledge. Based on the values of courage and trust, we focus on constantly developing ourselves as an organisation and as people. Read more at our website www.energinet.dk.
