S0830105 天売・焼尻島エコアイランドにむけたマイクログリッドの検討

Abstract

In Teuri Island and Yagishiri Island, in Haboro, Hokkaido, local production for local consumption of energy has become a challenge from the points of view of fuel transportation and conservation of local environment. Due to this, the "Eco Island Concept Demonstration Project" has been launched in Haboro, and the introduction of renewable energy is being considered. Therefore, this study aims at the developing of an optimal clean energy system in Teuri Island and Yagishiri Island. In this paper, the study of the optimization of the installed capacity and the suppression of frequency variation in the microgrid comprising these two island is performed. For the optimization of the infrastructure capacity, the objective function of the economics of the system is considered, and the most economically advantageous system with the less environmental impact is found. Moreover, focusing on the moment of inertia of the generator, whether the frequency variation falls or not within the permitted range for this economically optimum capacity is evaluated. Furthermore, this study reveals the differences between the experimental results and the simulation results by performing experiments using a smart grid simulator.
