Abstract
The transmission grid updates required to accommodate the envisaged massive amount of renewable energy sources in the transmission system go well beyond standard system reinforcements used in the past: in the coming decades, a North-Sea grid interconnecting various offshore wind farms is expected to be built.
The grid can gradually evolve into a European overlay supergrid connecting the offshore wind resources with the demand centers on the continent.
One of the challenges to use this technology relates to the control of the DC voltage in case of DC system contingencies, such as a converter outage. In this presentation, we will deals with various aspects with respect to the modelling and control of VSC HVDC in a meshed DC grid and multi-terminal DC systems in general. Models are developed to address both the interactions with the AC system and the control of the DC system. Amongst others, the influence of the DC voltage control on the power flows in the AC and DC systems will be described. Furthermore, the impact of a distributed DC voltage control on the AC system transient stability is investigated, as well as the influence of the DC system layout on the DC voltage control after a contingency.
