摘要
Abstract
An approach to modeling and correcting the computational data in discrete domain is presented in this paper to improve the convergence properties of power flow calculation.The proposed algorithm monitors the changes of node voltage data in the network during iterative computation;after the oscillation of data is judged,a discrete system model is established to conduct equivalent analysis;the eigenvalues of the system can be transferred to the convergent domain using an output feedback method,so that the iterative computation can avoid the oscillation.The correctness of the algo-rithm is verified by taking an IEEE 33-node system and a 198-node distribution network as numerical examples. The proposed algorithm can make the power flow calculation program become a closed loop algorithm at the cost of a small amount of storage space and computation load,thus it has a wide range of applicability.关键词
