Thesis Work on Investigating converter-driven instability in MVDC grids
ABB
At ABB, we help industries outrun - leaner and cleaner. Here, progress is an expectation - for you, your team, and the world. As a global market leader, we'll give you what you need to make it happen. It won't always be easy, growing takes grit. But at ABB, you'll never run alone. Run what runs the world. This Position reports to:
R&D Team Lead Your role and responsibilities With advances in Solid State Transformers (SSTs), MVDC technology is becoming more accessible and mature for marine, mining, railways, etc., as well as for collector networks. Despite their many benefits, MVDC grids, especially the multi-terminal MVDC and AC-DC parallel networks, are susceptible to CDI (converter-driven instability). These CDIs could have various causalities such as interactions between converter control loops, and ac or dc network parameters. To support the growing adoption of MVDC technologies, it is therefore important to assess the stability of MVDC networks under varying topologies and control. Details:
