摘　　要：交直流输电通道建设和跨省跨区电力市场正在我国稳步推进,但尚缺乏电力市场环境下的交直流输电通道功率优化分配计算的研究。为此提出一种跨省跨区中长期电力市场环境下的两阶段交直流输电通道功率优化分配方法。第一阶段针对协议计划电量,利用交替方向乘子法实现交直流输电通道功率优化分配与区域内发输电优化调度间的协同计算;第二阶段针对市场化交易增量电量,建立交直流输电通道功率分配方案调整模型。通过两阶段的分配计算,得到最终的交直流输电通道功率分配方案。通过对三区域交直流混联系统的仿真验证了所提方法能够在电力市场环境下实现交直流输电通道功率的合理分配。The construction of HVAC/HVDC transmission channels and the development of the inter-provincial and inter-regional power market are advancing steadily in China.However,there is no research on the optimal power distribution calculation of the HVAC/HVDC transmission channels under the power market environment.A two-stage HVAC/HVDC transmission channel power optimal distribution method under the medium and long-term power market environment is proposed.In the first stage,according to the protocol electricity,the cooperative calculation between the optimal scheduling of intra-region generation and transmission and the optimal power distribution of HVAC/HVDC transmission channels is realized by using the alternating direction method of multipli-ers.In the second stage,according to the market increment electricity,the transmission channel power distribution scheme adjustment model is established.The final HVAC/HVDC transmission channel power distribution scheme is obtained through two-stage distribu-tion calculation.Simulation results of a three-region HVAC/HVDC hybrid system verify that the proposed method can achieve the reasonable power distribution of transmission channels under power market environment.
