摘要
对比分析了基于直流和交流潮流的功率传输分布因子,认为交流的功率传输分布因子更能准确反映系统运行点变化对潮流的影响。文中还把交流传输分布因子与基于交流潮流的输电权相结合,为我国实现交流模型下的输电权交易探索了新思路。IEEE9节点算例表明了交流功率传输分布因子比直流功率传输分布因子具有更高的准确性及有效性。
After comparing and analyzing the power transfer distribution factors （PTDF） based on DC and AC power flow respectively, the authors consider that the AC power flow based PTDF can reflect the influence of variation of power system operating point on power flows more accurately. In this paper, the AC power flow based PTDF is applied to AC power flow based transmission right to search a new approach for transmission right transaction under AC model. The results of computation by IEEE 9-bus system show that the AC power flow based PTDF is more accurate than the DC power flow based PTDF and the proposed method is efficient.
