چکیده

To reduce the uncertainty nature of tidal stream turbines connected to the bulk power system, energy storage systems with high capacity should be used. among different energy storage systems, vanadium redox flow batteries with large capacity can be used in power systems. in this paper, an economic analysis is performed, and the impact of vanadium redox batteries on the power system containing tidal turbines considering reliability effect is evaluated. for this purpose, a multi-state reliability model is developed for tidal-stream turbines connected to battery units. the multi-state reliability model is used to study the adequacy of the power systems containing tidal turbines in conjunction with vanadium redox batteries. in the proposed reliability model, the failure rate of the composed components and variation in the generated power arisen from variation in tidal current speed are taken into account. fuzzy c-means clustering technique and xie-beni index are utilized to determine an optimal number of clusters and probability of them in the reliability model of the system including tidal stream turbines and vanadium redox batteries. numerical results of roy-billinton and ieee reliability test systems are evaluated to study the effect of tidal stream turbines and vanadium redox batteries on the reliability of power systems and verify the effectiveness of the proposed model.
