大规模电网的动态无功优化算法
Algorithm for Dynamic Reactive Power Optimization Problem in Large Power Grid
摘要
Abstract
In order to resolve the so-called problem of "curse of dimensionality", this paper analyzed dynamic reactive-power optimization by using nonlinear primal-dual interior-point algorithm which introduced discretization penalty and showed the further exploration of block-matrix decoupling method used in the coefficient matrix of the reduced linear correction equation. Moreover, a realization of exchanging time for space (time-space transformation) by twice computing coefficient matrix of the reduced linear correction equation and its triangular factorization which can reduce the data storage is given. The numerical results on IEEE 118-bus system and two real power supply systems with 14 nodes and 538 nodes show that the proposed algorithm is suitable for u-sing in large-scale power systems and has fast calculation speed.关键词
