A Predictor-Corrector Method for Power System Variable Step Numerical Simulation

Year: 2019

Type: article

Abstract: This letter proposes a predictor-corrector method to strike a balance between simulation accuracy and efficiency, by appropriately tuning the numerical integration step length of a power system time-domain simulation. Numerical tests indicate that by estimating the truncation error for step length tuning based on the two-step Adams-Moulton method and the implicit Trapezoidal method, the proposed method can provide much more precise results at little cost of efficiency compared to a conventional variable step method based on Newton's method.
