Sažetak
Steplength selection plays an important role in a continuation power flow and is the single most critical issue in the successful implementation of continuation methods. A continuation power flow employs a continuation method to find the solution path of a set of power flow equations. Effective continuation method solves the problem via four basic elements: predictor, parameterization, corrector, and steplength selection. Predictor, parameterization and corrector can be chosen independently of each other. Steplength selection must correspond to the predictor, the corrector and underlying parameterization. Steplength selection can be done by optimal fixed steplength or by adaptive steplength selection. This paper investigates the problem in the frame of parametric voltage stability and security analysis (load power parameter space). The most important point of the paper is to show that there is a significant and strong connection between the steplength selection and damping strategies common to Newton method. In particular, widely studied and well-understood damping strategies can have application to the problems of steplength selection and prediction. A version of the continuation power flow using damped Newton-Raphson method, is presented in the paper. All examples, included in the paper, are based on the real-life Bosnian Electric Power Utility System.
