N-1 security is an important concept to guarantee a reliable and secure power transmission. In this paper, a Current Injection method is presented which accurately determines the system state in case of a line outage without carrying out a full load flow calculation. The accuracy of this method is investigated and it is incorporated into an Optimal Power Flow problem where the objective is to e...
