Presentation Summary
The U.S. has ambitious goals related to the integration of offshore wind deployment of 30 GW by 2030 and 110+ GW by 2050. This session will address some of the main challenges the country is facing in this regard, particularly in terms of offshore transmission. Alongside covering challenges linked to HVDC connections (including procurement, permitting and grid reinforcement challenges) and technical challenges (linked to offshore meshing, Loss of Infeed, interoperability, standardization), the session will cover the main differences between the European and U.S. approaches.
The building of the HVDC grid will not be done from scratch. More likely, a phased approach will have to be adopted. From the developer point of view, cost optimized and low risk solutions are seen as attractive, meaning that non-selective protection strategies are preferred at early development stages, with possible transitions to partially selective or fully selective protection strategies in later stages. The main advantage of this approach is that some of the uncertainties in the technology might be solved on the way (DCCB, multi-vendor, interoperability...).
The challenges will be shown on two use cases: ongoing solicitation PPTN New York and New England.
