【摘要】：優(yōu)潮流的半定規(guī)劃松弛方法可提高優(yōu)解的質(zhì)量,但存在計算時間長的問題。為此,提出了半定規(guī)劃優(yōu)潮流的并行計算方法。該方法對半定規(guī)劃原始-對偶內(nèi)點法中的Schur方程采用并行方式進行計算,方面,將系數(shù)矩陣各行的計算量分配到不同的處理器上完成,以加速方程的形成;另方面,對系數(shù)矩陣進行并行Cholesky分解,從而加速方程的求解。IEEE-118節(jié)點和IEEE-300節(jié)點2個系統(tǒng)的計算結(jié)果表明:所提并行算法的加速效果明顯,并保持了內(nèi)點法的良好收斂性,為半定規(guī)劃優(yōu)潮流的工程應用提供了可借鑒的經(jīng)驗。
[Abstract]:The semi-definite programming relaxation method of optimal power flow can improve the quality of optimal solution, but it has the problem of long calculation time. For this reason, a parallel computation method for optimal power flow in semidefinite programming is proposed. In this method, the Schur equation in the primal-dual interior point method of semidefinite programming is calculated in a parallel manner. On the other hand, the computation of each row of the coefficient matrix is assigned to different processors to complete the calculation to accelerate the formation of the equation. The parallel Cholesky decomposition of the coefficient matrix is carried out to accelerate the solution of the equation. The computational results of two systems, I. E. IEEE-118 node and IEEE-300 node, show that the acceleration effect of the proposed parallel algorithm is obvious, and the good convergence of the interior point method is maintained. It can be used for reference in engineering application of optimal power flow in semidefinite programming.
