PhD
Ancillary services from offshore wind power plants in HVDC grids

Project Description
While the appliances are working perfectly in your home, actually, there are always unexpected disturbances in power systems deteriorating system stability and power quality, which are mostly handled by ancillary services. In my project, I will evaluate the potential of offshore wind power plants in providing ancillary services and optimize their utilization, although offshore wind power plants themselves are usually one of the disturbance sources due to wind fluctuation. What make the project even more challenging are the HVDC grids since they share distinct properties with conventional AC grids and we don’t have them in Europe yet. This project will help achieve more reliable and economic offshore power transmission and ultimately contribute to climate neutrality.

Background
I spent all my past 25 years in Wuhan, China, a world-famous city since 2020. I received both my bachelor’s and master’s degrees in electrical engineering at Wuhan University. Like many others, the 18-year-old teenager didn’t really have a clear idea about what major he had chosen, but later all his experiences converge to the road under his feet. During undergraduate, I extensively tried optimization, prediction, classification, etc. Afterwards, I found my passion in dynamics, and during master study, I focused on the primary frequency control of energy storage device to accommodate large-scale variable renewable energy, which finally led my way to ADOreD.
Motivation
Approaching the end of master's studies, I realized that while I could well solve the problems assigned to me, I desired the autonomy to forge my own path. This led me to pursue a PhD, envisioning that I can thereby cultivate the independence and knowledge base necessary to navigate my chosen field. Then, the ADOreD project stood out as a unique opportunity, providing invaluable networking and an ideal blend of academic and industrial training conductive to practical research. Besides, I see offshore wind energy development as a promising avenue that can not only benefit all mankind with cheap and clean energy, but also make a profound contribution to a carbon-neutral future, which is definitely worth my dedication.
