Abstract :
Introduction: Among different renewable energy sources, ocean is considered as one of the renewable energy sources that has a wide geographical range. Marine currents have different categories that tidal currents are among these currents. Near Japan, there is a current in the ocean known as the Kuroshio Current, which has a high potential for generating electricity. These currents have speed and consequently kinetic energy and can generate electricity by using turbines installed deep in the ocean. One of the problems that these currents have is that they change over time and therefore the power generation of energy converters of Kuroshio currents also varies. Therefore, the effect of these changes on different aspects of these converters such as reliability should be investigated. Materials and Methods: In the reliability model of the current converter, both the component failure and output power variations, which are caused by the change in the speed of ocean currents are considered. Results and Discussion: In this part, a Kuroshio Current energy converter that includes a turbine with a diameter of 2 meters is considered. In this part, the reliability indices of a sample test system are obtained, and then the effect of Kuroshio Current power plants on these indices is evaluated. The results show that as the peak load of the system increases, the reliability of the system deteriorates. Conclusion: In this paper, the reliability model of Kuroshio Current converters is obtained. Numerical results conclude that the Kuroshio Current converters can improve reliability indices of power system.
