Abstract
This paper is an analytical study of the optimal locations for tidal power generation in the Seto Inland Sea (SIS) in Japan. Multiple criteria were considered and evaluated to determine the optimal locations in the SIS to deploy tidal turbines. The tidal current speed was considered in a position of 30 m depth below the sea surface, given that most of the current commercial turbines are functioning between 20 and 50 m underwater. Also, the distance from ports and the coastlines was included for the installation and maintenance of tidal devices. The distance from existing power generation plants is also considered for the outcome energy to be easily inserted into the grid. Further, renewable energy resources from wind and surface waves are also considered in the analysis for the potentiality of a combined power generation. The national parks and restricted areas were eliminated from the selection process. The assessment process was conducted using the analytic hierarchy process (AHP) in combination with GIS-based spatial analysis. The results illustrated that Kurushima Strait, Bisan Strait, Naruto Strait, and Akashi Strait are suitable locations for tidal power generation. Moreover, Bungo Channel and Kii Channel are highlighted as potential sites for wind-wave power generation sites.
