Outline of Final Research Achievements

The purpose of this study is to design the smart community system based on energy flow and energy map in Tohoku area that was damaged by the Great East Japan Earthquake. Energy flow shows the quantities of primary energy supply of each fuel, energy conversion efficiencies of each technology, and energy consumptions of each sector. Energy map consists of the layers such as resource distribution, road network, and demand distribution.
As case studies, the district heating systems (DHS) using local resources in Mogami town, Miyako city, Ofunato city, and Hirosaki city are designed based on the energy map of heat demand. The heat transportation network and the plant location are optimized with cost minimization by solving mixed integer linear programming. As a result, DHS is installed in central area of each city even if the heat density is less than 4.2TJ/ha that is conventional baseline of DHS in Japan. Obtained results are cited in the reports of smart community framework in each city.
