鉴于自适应化简等值算法的有效性,本文提出了一个电力系统预想事故快速分析的新算法,该逄法首先构成了包括断开支路在内的局部等值小网,然后利用快速前代和快速回代技术对等值小网进行AC潮流求解,通过对IEEE-57节点试验系统和华东158节点系统的验算,证明该算法不但有令人满意的精度,而且有较理想的机时节约。 相似文献

Network losses allocation is one of the major problems in the market environment. The quadric function of the injected nodal power is used in this paper as a representation for network losses, which are allocated fairly using the called market equilibrium principle while the bidding curves are corrected. The power market equilibrium is simulated as three different models that can be solved simply by the optimal power flow algorithm combining the generation scheduling problem with network losses allocation. The case study is made at an IEEE-30 nodes system and a perfect result is proved in this paper. 相似文献
