摘要
当大量分布式电源并入配电网后,配电网的结构改变,原始节点编号或支路编号也可能改变。通过对各类常见分布式电源的工作原理进行分析,建立数学模型。以IEEE33节点为例,采用一种改进的前推回代计算方法,在不需要对网络重新编号的情况下,便可以对含分布式电源的配电网进行潮流计算,并分析不同类型、不同容量及不同安装位置的分布式电源对配电网产生的不同影响。计算结果表明,该算法能够有效处理含分布式电源的配电网络,并且相对于随意编号的网络也能够进行高效分析,使计算更加灵活。
When a large number of distributed generations are incorporated into the distribution network,the structure of the distribution network changes,and the original node number or branch number may also change.Mathematical models are built by the analysis of the working principles of various common distributed generations.Taking the IEEE-33 node as an example,an improved back/forward sweep algorithm can be used to calculate the power flow of a distribution network with distributed generations without renumbering the network.Moreover,the different impacts of distributed generations of different types,different capacities and different installation locations on the distribution network can be analyzed.The calculation results show that the proposed algorithm can well handle the distribution network with distributed generations,and it can be analyzed well with the randomly numbered network,which makes the calculation more flexible.
