含多端口电力电子变压器的配电网潮流计算:一种改进的交直流解耦迭代方法
Power flow calculation for a distribution system with multi-port PETs: an improved AC-DC decoupling iterative method
摘要
Abstract
Recently, power electronic transformers (PETs) have received widespread attention owing to their flexible networking, diverse operating modes, and abundant control objects. In this study, we established a steady-state model of PETs and applied it to the power flow calculation of AC–DC hybrid systems with PETs, considering the topology, power balance, loss, and control characteristics of multi-port PETs. To address new problems caused by the introduction of the PET port and control equations to the power flow calculation, this study proposes an iterative method of AC–DC mixed power flow decoupling based on step optimization, which can achieve AC–DC decoupling and effectively improve convergence. The results show that the proposed algorithm improves the iterative method and overcomes the over-correction and initial value sensitivity problems of conventional iterative algorithms.关键词
