Reliability assessment of composite power systems containing sea wave slot‐coned generators

The impact of variation in water flow rate and temperature on reliability analysis of run of the river power plants

“…Drawbacks [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15] Reliability evaluation of the electric network containing renewable energy-based units is performed Constant components failure rate is considered [16][17][18] Reliability assessment of electric network containing wind and tidal turbines considering speed variation is performed Reliability analysis of ROR plant is not performed.…”

“…In [4][5][6][7][8][9][10][11][12][13][14][15], the authors use similar approaches based on the analytical method applied in [1,2], for developing a multi-state reliability presentation of other renewable sources including wind farms, photovoltaic systems, central receiver power plants, barrage kind tidal units, stream kind tidal turbines, wave generators, and ocean thermal power plants. Here, for reducing the number of power states caused by change of renewable resources such as wind velocity, sun radiation, level of tides, tidal stream velocity, the level and period of waves, and temperature of the water placed on the ocean surface, fuzzy c-means clustering technique is suggested.…”

“…For reliability modelling of renewable energy-based power plants, two aspects of them should be considered: the impact of composed components failure and the impact of variation in the renewable resources. In [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15], the impact of composed components failure on the overall failure of plant is addressed to determine the equivalent failure rate of the plant. Besides, the impact of variation in the renewable resource on the reliability model of the plant that results in the multi-state model is considered in the mentioned papers.…”

“…Due to the variation in the renewable resource, the failure rate of composed components of the renewable energy-based power plants may vary that must be considered in the accurate reliability analysis of the power systems containing these generation units. However, in [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15], hazard rates of assembled elements are considered to be constant, and the impact of the variation in the renewable resources on the failure rates is not considered. Due to the importance of the variable failure rates of the composed elements of wind, photovoltaic and tidal units caused by change of renewable resources, papers [16][17][18][19][20] have been devoted on reliability analysis of wind turbines, photovoltaic systems, and barrage kind tidal units and tidal turbines considering the resource variations.…”

A wave energy converter based on a zero-pressure-angle mechanism for self-powered applications in near-zero energy sea-crossing bridges

“…Oliveira et al [23] analyzed the effect of waves focusing on the wall (wave concentrator) for the performance of the SSG unit and found that the focusing wall increases the bandwidth of waves that can capture a large amount of power generated. A previous study [24] proposed a multi-state reliability model for SSG composite power systems that predicts and improves the optimum state of the WEC. Overtopping WEC can capture wave energy over a wide bandwidth but is less efficient at converting wave energy into mechanical energy based on the PTO system.…”
