The opportunity
Integration of converter-interfaced production plants such as wind farms, solar plants and consumption plants example PtX plants and green steel plants requires careful consideration of their impact on the overall behavior of the transmission system. To ensure the safe and stable operation of the system, grid code requirements are defined for both generation (RfG) and consumption (DCC). Additionally, country and project specific requirements may be imposed. In addition to the requirements on the plant's physical behavior, TSOs require plant owners to perform calculations and simulations, end goal being to demonstrate grid code compliance. Subsequently, grid code compliance reports and associated models need to be delivered to the TSOs as a proof of compliance.

The choice of the technology used in the production plants such as DFIG or full converter turbines or consumption plants thyristor-based or active front-end converters has great impact on the ability of the plant to satisfy the grid code requirements. The goal of this Master Thesis is to analyze the impact of converter technology on the grid code compliance relative to the grid codes of Sweden, Norway and/or Finland for both RfG and DCC. To that end, several representative models of such plants shall be developed in the relevant tools example DIgSILENT Power Factory, PSS/E, PSCAD. Using these models as a base, an automated grid code compliance testing framework shall be developed to support the analysis of a plant's behavior and the impact of the converter or rectifier technology selection on fulfillment of the grid code requirements. Corrective measures to the plant's design shall be proposed if non-compliance is identified such as inclusion of a STATCOM device. Comparative techno-economic analysis of different technologies and system designs shall be performed based on the grid code compliance tests and the economical evaluation of different solutions.
We are looking for two students who are executing the thesis work in a team. The students will receive extensive support from the Hitachi Energy team of power system experts and direct supervision by technical consultants at Hitachi Energy Power Consulting.
How you'll make an impact
- Model representative plants in the relevant power system simulation tools.
- Develop a grid compliance testing framework to support the analyses.
- Make a techno-economical evaluation of the different technologies for interconnection.
- Study how different technologies for interconnection of production and consumption plants impact the plant's ability to satisfy grid code requirements.
Your background
- Student with master's degree in electrical engineering, electrical power systems or similar.
- Understanding of working in a multi-cultural environment.
- Proficiency in MS Office, Python and one of the simulation tools such as Power Factory, PSS/E, or PSCAD.
- Fluency in English, and Swedish is a merit.
