摘要
本文采用基于仿射变换的内点算法进行大型电力系统无功代化。这种方法,将标准化后的约束系数矩阵进行分块处理,通过利用矩阵求逆的反演公式,保留了系数矩阵高度稀疏的特点,极大地加快了计算速度,降低了对内存的需求量,从而使用于大型电网无功优化的内点算法向实用化前进了一步。对实际电网的优化计算表明,本文算法具有良好的特性。
This paper presents an affine transformation based interior point algorithm for reactive power optimization in bulk power systems. By partitioning the constrained coefficient matrix standardized and using refutation formula, the high sparsity of the coefficient matrix is remained.As the results, the solving process for optimization is speeded up greatly. On the other hand, the requirement for memory is monomozed. Tested on a number of practical power systems, the results show that this method is effective.
