Analysis of Long- and Medium-Term Power System Voltage Stability Based on Semi-Tensor Product and Quasi-Steady-State Time Domain Simulation
摘要
Abstract
A method to judge medium- and long-term voltage stability, which integrates the non-linear dynamic stability margin index based on semi-tensor product with quasisteady state(QSS) time domain simulation, is proposed and a medium- and long-term voltage stability analysis model is built.The built model turns the short-term dynamic balance equaons into algebraic equations, thus the complexity of computation of Jacobian matrix and Hessian matrix during solving stability margin index can be reduced. On this basis,the medium and long-term voltage stability index based on semi-tensor product is used to analyze medium- and long-term voltage stability The effectiveness of the proposed method is verified by simulation results of New England 10-machine 39-bus system.关键词
