Abstract: |
To solve the power supply problem of AC/DC hybrid power grid with high proportion of renewable energy, the research framework of power grid planning is proposed. It firstly summarizes the structure profile of the AC/DC hybrid power grid with high proportion of renewable energy. Considering uncertainty and more power electronics’ integration, new challenges for planning in scenario extraction, planning modeling, optimization strategies and operational simulation are indicated. Five aspects on the research are discussed, including “generation-network-storage-load” collaborative planning, uncertain scenario construction, AC/DC grid optimization, converter equipment configuration and power flow analysis. Finally, with the advantages of AC/DC hybrid power grids in energy market transactions, the key research points are prospected.
