摘要

本文提出了一种高效潮流（LF）技术，该技术具有改进的收敛特性，可用于具有电压相关负载（VDL）的平衡径向配电系统（RDS）。这种方法的关键促成因素是构建负载注入到总线电压（LIBV）矩阵，该矩阵用于在一个步骤中执行功率流的前向扫描计算。总线电压可以通过结合LIBV矩阵直接从负载注入中确定，与其他LF技术相比，LIBV矩阵又减少了执行时间。此外，提出了一种新的广义算法来快速构建LIBV。此外，本文还考察了年负荷增长的影响。所提出的技术在三个平衡基准RDS上进行了测试，这三个基准RDS是具有不同VDL模型的30、33和118总线系统。与文献中其他方法的结果相比，所获得的结果证明了所提出的方法的有效性。此外，还表明，与用于分析具有VDL的配电系统的传统LF技术相比，所提出的算法在计算上更快、更鲁棒。

Time-Efficient Load Flow Technique for Radial Distribution Systems with Voltage-Dependent Loads

This paper presents an efficient load flow (LF) technique that exhibits an improved convergence characteristic to be employed in balanced radial distribution systems (RDSs) having voltage dependent loads (VDLs). The key enabler of this approach is the construction of load injection to bus voltage (LIBV) matrix that is utilized to carry out the backward forward sweep of power flow calculation in a single step. The bus voltages may be determined from the load injection directly by incorporating the LIBV matrix which, in turn, decreases the execution time when compared to other LF techniques. Further, a novel and generalized algorithm is proposed to construct LIBV in a fast manner. In addition, the effect of annual load growth is examined in this work. The proposed technique is tested on three balanced benchmark RDSs, which are the 30-, 33- and 118-bus systems with different VDL models. The obtained results demonstrate the effectiveness of the proposed approach compared to the results of the other approaches in the literature. Also, it is revealed that the proposed algorithm is computationally faster and more robust than the conventional LF techniques that are used to analyze distribution system having VDLs.
