Abstract
The development of energy systems based on distributed generation has become an important target in Japan after the Fukushima Daiichi nuclear power plant accident. Moreover, in regions with cold climates, such as Hokkaido, heat supply must also be taken into account. This study aims at the development of an optimal energy system based in the introduction of renewable energy in order to supply power and heat to the Teuri-Yagishiri Island in Hokkaido. It is assumed the introduction of solar power and wind power generation, together with heat pumps and heat storage tanks for heat supply. The system is modeled and studied from both economic and power quality points of view.
