【 摘 要 】

Interconnected converters are an important part of AC/DC hybrid microgrids. This paper fully considers various factors affecting the capacity configuration of interconnected converters, and proposes the principle of optimal capacity allocation to meet the power exchange requirements between AC and DC hybrid microgrids and meet the requirements of reliable power supply for important loads. According to the operation requirements of AC/DC hybrid microgrid under different scenarios, two optimal capacity allocation methods for power supply continuity and economy are given. Finally, the AC/DC hybrid microgrid project with island operation is taken as an example to verify the effectiveness of the proposed method, and the influence of important parameters is discussed in depth. The optimal configuration of interconnected converter capacity is given.
