摘要
目前分布式电网的潮流优化算法主要面对三相功率平衡系统,对于三相不平衡系统进行分析的算法介绍较少。文中利用内点法,结合美国电科院的开放式配电仿真系统分析(OpenDSS)平台,提出了三相不平衡分布式电网潮流优化算法的研究。该算法以网损和变压器三相潮流不平衡度最小为目标,以系统潮流、发电机和线路极限容量为约束,以变压器分接头和电容器投切为控制变量,建立了优化函数,利用内点法作为优化算法,以OpenDSS为计算平台。文中最后以IEEE123测试节点和IEEE9500测试节点为例,验证了文中算法的有效性和实用性。
Optimal power flow methods were mainly designed to solve balanced three-phase distributed system. Little of them could be applied to unbalanced three-phase distributed system. A method of unbalanced three-phase optimal power flow for distributed system is present in the paper, based on EPRI＇s open source project OpenDSS and interior point method. The method employs maximization of energy losses and unbalance level of transformers, subject to meeting power flow, capacity of generator and lines, with transformer tap and capacitor switching as control variable, utilize interior and OpenDSS as compute platform. Taking the IEEE123 and IEEE9500 test systems as example, the effective and practical of the method is proved.
