Vacant job

Do you want to contribute to the energy transition and work in a developmental environment where you become an important link in a socially vital operation? As society electrifies at a rapid pace, the energy sector faces several major challenges. Sweden needs to quickly double electricity production, expand the power grid, and simultaneously transition to renewable energy. Do you want to help make this possible? Then you might be one of our future thesis students!

Svenska kraftnät is a state-owned business agency that serves as the system-responsible authority for the power system in Sweden and manages and develops Sweden's electricity transmission grid.

The Grid Planning Development unit is responsible for Svenska kraftnät's grid development plan, the management and development of the grid planning handbook, forecast collaboration, method development, and design criteria for grid planning. The unit is also responsible for the overall strategic design and dimensioning within grid planning. Furthermore, the unit holds the strategic responsibility to ensure the power system's voltage stability through requirement setting, follow-up, analysis, and method development.

The Grid Planning Development unit works on developing tools and methods to streamline the execution of requirement analyses and more general studies within system stability, with a special focus on the voltage area. Currently, planning grids for the power system are used to perform studies. These types of grids are very extensive and complex, which has sometimes made them less useful for quickly conducting overall studies. Therefore, the voltage area within the unit wants to develop a flexible and adaptable tool to quickly perform overall analyses on the power system.

The purpose of the assignment is to investigate, based on the studies the unit requires, what a model corresponding to the unit's needs might look like, and to begin developing a dynamic model in PSSE. The developed model should be usable to efficiently and comprehensively analyze relevant voltage stability phenomena and voltage collapse, with the aim of identifying future grid needs.

The developed model can advantageously be based on the Nordic32 model but adapted for current conditions in the power system and the needs of Svenska kraftnät.

Your profile/background

• Master of Science in Engineering with a focus on electrical engineering, power systems, technical physics, or equivalent.
• Understanding of power systems, model development, Python programming.

We consider it an asset if you have:

• Experience with PSSE, Power Factory, or similar analysis tools.

As a person, we are looking for someone who is structured and can approach problems in a methodical way. You can take your own initiatives and work independently but are not afraid to ask for advice or support when needed.

You should be proficient in both Swedish and English, both spoken and written.

Since we work with important infrastructure in society, our services are security-classified, and Swedish citizenship is therefore a requirement.
