摘要:

为了解决含高比例可再生能源的交直流混联电网供电问题，提出了电网规划的研究框架。首先总结了含高比例可再生能源的交直流混联电网的结构形态特性，围绕多重不确定性和电力电子化两个关键驱动因素，指出了系统规划在场景提取、规划建模、优化策略和运行模拟等方面面临的新挑战。从五个方面评述了国内外研究成果，包括源网荷储协同规划建模、不确定性场景构建、复杂交直流网架优化、换流设备配置优化以及潮流分析。最后，结合交直流混联电网在能源市场交易中的优势，展望了电网规划研究中的关键研究点。

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. This work is supported by Science and Technology Project of State Grid Corporation of China (No. SGSCJY00 GHJS1800026).

Key words: AC/DC hybrid high proportion of renewable energy planning power flow converter
