A Zero-injection Initialization Numerical Method for Ill-conditioned Power Flow

Abstract Regarding the initial value sensitivity issues commonly found in Newton-like power flow calculation algorithms, a zero-injection initialization numerical method for ill-conditioned is proposed this paper, which improves convergence of systems. Based on provided by method, unbalanced active each bus (the slack excluded) relates to net injection that and reactive PQ bus, thus avoiding significant unbalance. The put forward herein can provide reasonable so difficulty caused unreasonable effectively avoided. Newton’s optimal multiplier are implemented respectively small-scale test system verify feasibility method.
