Frequency Response Reserves Sharing through VSC-HVDC for Interconnections

Sharing frequency response reserves through HVDC connections among the three Interconnections is expected to be one high value product that provides benefits to economically justify the HVDC Network. In this paper, A HVDC frequency response control scheme considered frequency response reserve allocation is developed for the VSC-HVDC links connecting asynchronous interconnections. The simulation results show that the proposed control scheme can greatly help the frequency stability of interconnection after contingencies of tripping the major generator while reducing the financial loss of disturbed interconnection during the event.
