I am an Electromechanical Engineer from Bolivia. I have more than 4 years’ experience in developing high voltage electricity projects and analysing the Bolivian and neighbouring countries’ power systems at the largest stakeholder in generation, transmission and distribution in the Bolivian electricity sector.
I obtained my MSc in Electrical Energy Systems at Cardiff University, which proved to be my biggest academic challenge at that time. It was the first time I had moved abroad to pursue a higher education degree in a language other than my mother tongue. While I was there, my research project supervisor suggested I publish a paper on my dissertation topic. It led to my presenting my work ‘Fast Frequency Support Control in the GB Power System using VSC-HVDC Technology’ at the 7th IEEE PES Innovative Smart Grid Technologies European conference in Turin, Italy in 2017.
During my work development, I understood the high penetration of HVDC technologies into AC power systems, mostly to connect large off-shore wind farms. This has an impact over the system stability by decoupling the inertia stored in the rotating mass of generators. This effect was something I achieved to mitigate in my work by designing a frequency support control scheme over the HVDC-VSC converters.
The opportunity presented as an Early State Researcher is very exciting and challenging. By being trained in specialised software, I have simulated, averaged and switched HVDC-VSC models in MATLAB and PSCAD and validated them in an experimental test rig. I believe that I can contribute to InnoDC both with my academic and professional experience. Moreover, I am very enthusiastic about developing my knowledge and new skills.
There is plenty of research still to be done, such as the one I would like to undertake. I believe the future of HVDC technologies is promising and a key enabler towards renewable energy integration.
