Abstract
From the viewpoint of efficient use of limited resources and energy, distributed district energy system is attracting great attention, which enables efficient use of both electricity and heat by promoting the utilization of local resources and taking advantage of the proximity between supply and demand. In comparison with the large-scale centralized system, although the planning and management of the system corresponding to each regional and district condition is quite important, many of the past practices are mostly designed and operated depending on the individual experience, the knowledge are still not sufficiently generalized. Therefore, this study aims to build a framework to support the design of distributed energy system quantitatively and confirm its effectiveness by a case study of actual district development project, which is currently in progressing in a revitalization municipality of the Great East Japan Earthquake.
