摘要:
为了实现全网理论线损的在线计算,本文在已有分解协调计算模型的基础上,提出了一种 适用于大规模电网的线损并行计算方法。该方法使用改进的Fast-Newman 算法进行网络划分,减 小边界协调量的影响,实现不同类型网络的线损计算方法选择;进而利用外层缓冲网等值,引入双 层迭代算法,通过边界向量的外层迭代实现子网边界状态量的一致收敛。应用Matlab 并行工具 箱,在IEEE 39 节点系统和实际的地区电网上进行验证,结果表明本文方法具有良好的计算精度和 加速效果,适合应用于在线计算系统。
Abstract:
For achieving the online calculation of the theoretical line loss for the whole network,in this paper a kind of parallel calculation method of line loss for large?scale power grid is proposed on the basis of the existed decomposition coordination calculation model. The method uses the improved Fast?Newman algorithm for network division,reduces the influence of boundary coordinationand realizes the selection of line loss calculation methods for different types of networks. Then,a double?layer iterative algorithm is introduced by the use of equivalent value of the outer buffer network so to achieve the uniform convergence of the state quantity of the sub?net boundary through the outer iteration of the boundary vector. The Matlab par? allel toolbox is used for verification on IEEE 39 node system and the actual regional power grid. It is shown by the result that the proposed method has good computational accuracy and acceleration effect and is suit? able for online computing systems.
