A powerful power-flow method based on Composite Newton-Cotes formula for ill-conditioned power systems

Abstract

This paper proposes a novel Power-Flow method based on Composite Newton-Cotes formula. The proposed method aims to be robust and efficient enough to properly manage ill-conditioned power systems. Self-adapted mechanisms for tuning the parameters of proposed PF method are provided. The proposed method is tested on several ill-conditioned systems ranging from 3012 to 27,318 buses at loadbase and heavy loading conditions. Moreover, its ability to handle the generators’ reactive limits is also tested. The obtained results prove that the proposed method is remarkably robust and more efficient than other well-known Power-Flow techniques.
