基于简单图的配网潮流递归前推回代法

提出一种直接利用配电网络树状拓扑结构进行配网前推回代潮流计算的算法,此算法利用了树状结构天然的可递归性,将前推和回代的过程都进行递归化处理,降低了算法实现的难度,提高了算法实现时代码的执行效率。由于直接在配网的树状拓扑结构上进行计算,本质上已经实现了排零的操作,因此等价于采用了稀疏技术进行求解。此算法在JAVA环境下基于开源图论函数库——JGraphT得以实现,以实际配电网的计算结果验证了本文所提算法的有效性。

Recursive Back/Forward Sweep Method Based on Simple Graph for Load Flow Computation in Distribution Systems

A new type of back/forward sweep method for load flow computation in distribution systems is introduced in this paper, which is implemented directly on the tree topology of traditional distribution systems. Intrinsic recursive realizahility of tree topology is utilized to reform the back/forward sweep processes, and thus the difficulty of algorithm implementation is reduced, while the code efficiency is enhanced as well. Calculation related with zeros is already excluded in the algorithm, since only the tree topology is considered, so it is equivalent to traditional sparsity technology. The method is implemented based on the open source graph theory package named JGraphT in JAVA environment. A sample from real distribution systems is used to test the validity of the method in this paper.
