摘要 发电转移分布因子(GSDF)和广义发电分布因子(GGDF)都是常用的灵敏度分析及安全评估工具。文中指出了GSDF和GGDF的缺陷,尤其对GGDF的普遍适用性提出质疑。提出了发电联合转移分布因子(GJSDF)和负荷模增发电联合转移分布因子(GJSDF-LIP)的概念,并导出若干有用的性质。针对电力市场环境下购电交易计划新模型和流畅调度算法的特点,将GJSDF和GJSDF-LJP成功地应用于静态安全校核算法中,极大地提高了求解速度。算例表明,该算法效率很高,并且易于编程实现。 Generation Shift Distribution Factors (GSDF) and Generalized Generation Distribution Factors (GGDF) are important sensitivity methods in power system security and contingency analysis. This paper points out that traditional GSDF and GGDF has some limitations for power system security analysis due to the assumption of slack bus. A clearer concept, Generation Jointly Shift Distribution Factor (GJSDF), is proposed to meet the requirements. Some useful properties of GJSDF are studied and can be used to accelerate power flow calculation and correction algorithm. In this paper, GJSDF is successfully applied in a typical trade scheduling algorithm and a novel liquidity dispatch algorithm. Furthermore, a novel concept, Generation Jointly Shift Distribution Factor Under Load Increment Pattern (GJSDF-LIP), is put forward to improve the algorithm efficiency more. These algorithms avoid the introduction of sparsity-oriented techniques and can be easily implemented. All above algorithms have been proved to be effective and fast.
