Abstract
This paper has the objective of developing an interconnected system using tidal, wind and solar generation in order to supply the total demand of Kitami City, in the Hokkaido Island. In addition, this paper proposes a seasonal energy shifting strategy by using an energy storage technology that employs organic chemical hydride using hydrogen as a medium, including an optimal equipment design planning. Results show that the optimal sizes of the equipment is composed of 95 sets of tidal turbines, 7.8×10^5 m^2 of solar farm, 400 to 500 sets of wind turbines, 0.1 to 0.5 GWh of NaS battery and 5.0×10^6 to 7.5×10^6 m^3 of hydrogen storage of organic chemical hydride.
