Offer Description

The large-scale integration of renewable generation and associated transmission system development projects cause transmission system dynamics to be increasingly more influenced by the fast response of power electronic converters at HVDC stations and renewable generation units. To mitigate undesired stability issues and resonance incidents transmission system operators express deep interest in detailed time-domain simulation studies to assess converter interactions across the transmission system. As converter interactions occur over a wide frequency range, analysis at time-scale of electromagnetic transients (EMT) with a detailed representation of converter response is generally desired. Simulation studies at this level of detail prompt multiple challenges, around which this project will be positioned.

• Stability analysis is typically performed in the continuous-time domain through linearization at an operating point and using time-domain state-space stability analysis of frequency-domain stability analysis.
• The importance of including control system implementation details such as measurement sensors, discrete-time control code, sample rate, modulation, and control delays of various origins, needs to be investigated deeper, as well as potential mitigation solutions.
• Such details often depend on the actual hardware architecture used to implement the control code. (Distributed control units with CPUs, DSPs, or FPGAs, and time-critical communication links).
• Converter manufacturers often provide only "black-box" compiled control system models to system operators, in which (parts of) the real control code is typically included and protected. The closedness of the control system model complicates analysis to find the root cause of interaction incidents.
• Approximations in EMT simulation often compromise the accuracy of discrete control timing.
• The computation time associated with large-scale EMT simulation with detailed models is often impractical. 

Candidates interested in a PhD on this topic should have a good understanding of modelling and control of power electronics converters. A strong interest and affinity in power system dynamics and simulations is essential. A keen interest or background in control systems and numerical simulation is crucial.
