Abstract :
In recent years, countries around the world have turned to renewable energy sources such as wind, sun, and oceans to provide sustainable energy. The driving force behind the growth in the use of these sources in electricity generation is the problems related to fossil fuels such as rising prices, greenhouse gas emissions, and environmental problems, as well as concerns about the depletion of these fuels. Ocean energy comes in various forms such as waves, tides, and ocean thermal energy, which, given the vastness of the oceans, can play a significant role in the future energy supply of the world. One of the problems related to renewable energy sources is the uncertainty of these sources, which has caused these energy sources to vary with time and also their changes to be random, so the production capacity of these sources may be low and insignificant when the grid load is increasing. Accordingly, power plants based on renewable energy sources are operated either separately from the power grid, but alongside energy storage devices, or in a state of connection to the power grid. On the other hand, with the increase in the level of welfare in today's societies, the reliability of the power grid has also become important and consumers expect electricity to be provided to them without interruption. In this paper, the reliability of a composite power system consisting of a generation and transmission system is evaluated in the conditions where wave power plants are present in the network and the production rate of these power plants is significant. These studies can be used to determine reliability indices and for decision-making in planning the development of production and also the development of the transmission system. In order to examine the proposed method, the results obtained from applying the method to standard test composite systems to which wave power plants have been added are presented
