    General Context

    HVDC technology plays a crucial role in the integration of renewable energy sources, such as offshore wind farms, into the power grid. While point-to-point and multi-terminal HVDC connections are already in operation, the future HVDC systems are foreseen to evolve into meshed HVDC grids. Bipolar HVDC system are considered the standard configuration, providing operational flexibility during outages affecting one pole. To ensure reliable and efficient system operation, power flow calculation tool that accurately models the independent behavior of both positive and negative poles, as well as neutral physical quantities is essential. This internship will focus on the development of such a power flow tool, which will not only facilitate the feasibility and design studies of HVDC systems but also enable security analysis of the systems. The tool will be validated against Electromagnetic Transient (EMT) simulations and extended to perform contingency analysis, based on the N-1 criterion. Additionally, the intern will work on enhancing the tool with system security optimization, incorporating control parameter sensitivity analysis and optimization techniques.
