An incomplete acceleration constant method improving convergency for transient load flow calculation

This paper presents an efficient transient load flow calculation using an incomplete acceleration method. This method does not use the LU factorization, which is the most time consuming part of a load flow calculation. Therefore, fast calculation can be carried out. The proposed method can be applied for the methods that have more inferior convergency than the Newton-Raphson method. To confirm the effectiveness of the proposed method, test calculations were carried out. The results show that the proposed, method is able to improve convergency remarkably than the constant Jacobian method and is faster than the Newton-Raphson method.
