The project “MULTI-DC: Innovative Methods and Optimal Operation of Multiple HVDC Connections and Grids” (multiDC) applied in 2016 for funding under the Innovation Fund Denmark framework of “Grand Solutions”. Due to the high number of HVDC connections in the Nordic region, this call pursues new and advanced control solutions to fully employ the benefits HVDC connection has to offer. The specific objective of multiDC project is to develop innovative methods for the optimal coordination of multiple HVDC lines
The increase of inverter-based generation is phasing out grid-connected generation units, which provide various system services, such as Short Circuit Capacity (SCC), frequency control and rotational energy. Moreover, the clustered renewable generation requires facilitation of huge power influx in a power system, which becomes increasingly challenging for TSOs to control. Due to high controllability and bulk power transmission capability, HVDC technology is a promising replacement to provide such services a
In the last decades, HVDC technology has become a common tool in the design of transmission grids. From a technical point of view, the full controllability of power converters gives the opportunity of supporting local AC networks by means of voltage control, frequency support and reactive power compensation. On the economic side, HVDC interconnectors facilitate the exchange of energy and ancillary services between countries. Thus, if HVDC and AC grids are operated in an optimal way, significant cost and ene
