Abstract: Island judging and processing is of great significance in power system reliability assessment.In order to improve the island judging and processing speed and accuracy,an island judging and processing method based on Matlab and Matpower is proposed.The method uses Matlab to establish the island discriminant matrix according to the nature of the islands,and then modifies the parameters in the Matpower for the Matpower to perform directly dc power flow calculation of the island system.Compared with the conventional manual calculation,this method offers higher speed as well as better accuracy and operability.

Key words: island;reliability assessment;Matlab;Matpower;dc power flow calculation
