Abstract：To address the issues of high energy consumption and poor stability in long-distance transmission of offshore wind power,the research focuses on the structural optimization of the DC transmission system and the grid connection control strategy.By combining theoretical analysis with simulation verification,the influence of transmission voltage level,lightweight converter platform,and cable transmission efficiency on system losses is analyzed.The maximum power point tracking technology(MPPT)dynamic power distribution,voltage stability coordinated regulation,and fault current limiting control strategies are proposed.System energy efficiency evaluation indicators are constructed.The results show that increasing the voltage level can reduce line losses.The SiC device converter scheme has a 32.8%lower energy consumption under light load compared to IGBT.Dynamic power control can reduce the energy consumption per unit of electricity by 8 kWh/MWh.
