Linear Power Flow Calculation of Distribution Network Considering Load Voltage Static Characteristics and PV Node
摘要
Abstract
In view of the fact that the original high-dimensional nonlinear power flow model cannot be applied to the linear planning of distribution network,and the existing linear power flow model has the problem of weak universality,a calculation method of distribution network linear power flow was proposed considering the static characteristics of load voltage and PV nodes.Based on the power flow equation in polar coordinates,the proposed method decoupled the voltage amplitude and phase angle of the power flow equation using the characteristics of the distribution network.According to the control characteristics of PV nodes,a linear power flow calculation model with PV nodes was derived.The proposed model not only considered the static characteristics of PV nodes and load voltages,but also considered the adaptability to overload and weak loop networks.It could solve the voltage distribution of distribution networks without iteration.The simulation results show that the proposed method has high accuracy and versatility,and can be used for rapid analysis of distribution networks.关键词
