An Improved Reduced-Dimension Interior Point Method for Transient Stability Constrained Optimal Power Flow
摘要
Abstract
An improved reduced-dimension interior point method is proposed for transient stability constrained optimal power flow (TSCOPF) in this paper. The two groups of differentiated implicit recursive equations of motion of the rotor are eliminated to be one set of equations through recursive features. Considering the truncation error of specific numerical integration algorithm, the transient differential equations are dispersed to inequality constraints instead of equality constraints. The method can reduce the number of the equality constraints and variables and the dimensions of the correction equation, improve the computational efficiency and reduce the memory usage. Numerical simulations on the three test systems, from 22 tol 18 buses, show that the proposed method is robust and efficient.关键词
