| 摘 要： | 针对交直流混合电网输电能力计算这一问题，建立包含多端直流系统的交直流电网可用输电能力（available transfer capability，ATC）的计算模型，提出一种主从迭代连续潮流算法，针对常规连续潮流算法中节点功率的恒功率因数增长模式，提出采用模态分析技术从考虑静态电压稳定的角度，找出一种对特定区域间ATC影响最大的负荷增长方式；发电机出力调整采用经济调度模式，实现了考虑静态电压稳定约束、兼顾安全性与经济性的ATC计算。将直流系统灵活的控制及调整策略以安全合理性原则融入迭代过程中。改进的IEEE30节点系统算例表明：所采用的节点注入功率优化模式及主从迭代连续潮流法能计算交直流电网的考虑静态电压稳定约束的安全经济的ATC，还能指出对系统ATC影响大的关键节点。

| Abstract: | To the recently emerging need of computing AC/DC hybrid transmission system's transfer capability,a model for the AC/DC system available transfer capability(ATC) determination with multi-terminal DC(MTDC) system was set up in this paper.A master-slave iterative continuation power flow(CPF) approach was proposed to solve the model.Instead of conventional linear nodal power increase mode,the modal analysis was adopted to find the worst load increase case for dealing with static voltage stability constraint in... |
