This paper proposes a multiperiod optimal dispatch model for hybrid voltage source converter based multi-terminal DC (VSC-MTDC) system and AC grids with consideration of optimal coordination of offshore wind farm (OWF) and battery energy storage (BES). The OWF is connected to onshore AC grid by VSC-MTDC. The VSC capacity limits and Grid Code for OWF connection to AC grid are taken into consideration. Scenario method is employed to model the wind energy output uncertainty. Simulation on the modified IEEE 118-bus system with three OWFs integration via seven terminal VSC-MTDC network is used to validate the availability and effectiveness of the proposed method.
