Assessing transmission system flexibility associated with wind power integration using well-being analysis

This paper utilizes the system well-being analysis concept to examine transmission system flexibility to accommodate large-scale wind power integration in a bulk electric system. The system flexibility is measured in the form of degrees of system adequacy and security. The basic N-1 deterministic security criterion is incorporated in a probabilistic assessment to monitor the system well-being associated with wind power integration. Sequential Monte Carlo simulation is employed to create system well-being index probability distributions together with their mean values. The results are illustrated using the IEEE - Reliability Test System (IEEE-RTS).
