摘　　要：电网可用传输容量(ATC)是电力市场化以来研究的重要课题之一。提出电力市场环境下计及风险的可用传输容量计算方法。首先建立基于最优潮流的区域可用传输能力模型,将跟踪中心轨迹内点法用于最优模型计算,并对预想事故进行合理选择,求解各个故障下可用传输容量的大小。其次,引入风险的概念,提出了可用传输容量风险的计算方法,再根据风险大小发布对应的可用传输容量。最后,采用IEEE-30节点系统对提出的方法进行了仿真计算,计算结果表明,计及风险的可用传输容量能更多地反映电力市场环境下系统运行的不确定性。The calculation of Available Transfer Capability（ATC） has become one of the most important research subject since the opening of power market.ATC calculation considering risk is proposed.Firstly,the OPF based ATC calculation model is established and a tracking center path interior-point algorithm is applied.Different ATC is calculated under different contingency.Secondly,the concept of risk is introduced to ATC calculation.The risk of the corresponding ATC is calculated and issued.Lastly,IEEE-30 bus system is used for testing the proposed method.The uncertainty of ATC under power market environment is indicated by using the proposed algorithm.
