摘　　要：南方电网具有交直流混联特点,对其进行交直流输电优化,是提高电网经济效益的主要策略。结合电网实际,将复杂的日计划优化问题划分为2步,首先将电网潮流调整为相应的日计划负荷水平,然后再对直流线路的输电计划进行优化计算。运行结果表明,该方法使交直流输电方式达到最优,具有较大的应用价值。The China Southern Grid （CSG） is featured by mixed AC/DC transmission and optimization of its AC/DC power transmission is a main strategy for improving its power grid economic efficiency. Based on the actual situation of the power grid, the complicated day-ahead schedule optimization is divided into two steps. First, the load flow of power grid is adjusted into the corresponding day-ahead schedule load level, and then optimization calculation is carried out on the DC transmission schedule. The operation results show that the proposed optimization algorithm can obtain the optimal AC/DC transmission mode and has high application value.
