Title: HVDC connections for integration of renewable generation - Operation, control and coordination
In recent years, the interest for Voltage Source Converter High Voltage Direct Current (VSC HVDC) in a Multi-terminal configuration has increased significantly. This interest can partly be explained by the expected massive integration of offshore wind power in the transmission system, as well as to the preliminary plans to construct overlay supergrids in Europe and in other parts of the world to integrate more renewable energy sources (RES). The DC connections may be used to balance the fluctuating RES based power generation between different areas. The operation and control of such DC grids and connections is crucial as improper actions may jeopardize the security of the overall AC/DC system. This talk presents concepts and challenges to operate, control and coordinate DC grids and connections for integration of RES. Control of the DC voltage is vital in the DC system and will highly influence the interaction with the AC systems. Proper control and coordination may reduce negative interactions between the systems originating from a disturbance on the AC or DC side. Moreover, it may additionally improve the security by e.g. fast power balancing to improve the rotor angle stability or sharing of frequency reserves between areas. However, it is unacceptable to help one area whereas the consequence is a blackout in another, hence, the need for coordination.
