論文概要:In this paper, INTEGRATION STUDY ON DISTRIBUTED ENERGY RESOURCE AND DISTRIBUTION
SYSTEM is devoted to optimization on the distributed energy system. The main works can be
summarized as follows:
Pervious study
In this part, present situation on energy and utilization of distributed energy source in Japan has
been investigated. Next, the previous researches on the distributed energy resource and distributed
energy system have been previewed.
Investigation and question
In this part, In order to grasp the use present situation of the introduction and the existing
problems in distributed energy system, the questionnaire survey has been carried out in Tokyo,
Japan. The problem of distributed energy system in Japan has been clarified. Next, a new distributed
energy system including fuel cell, gas engine and PV system at Kitakyushu Science and Research
Park (KSPR) in Japan, has been analyzed by using the recorded data during 2002 and 2003.
Generating electricity system and heat recovery system were analyzed respectively.
Evaluation method
In this part, comprehensive system has been developed to evaluate the distributed energy system
regarding of saving energy, environment and economy. It is capable of evaluating the feasibility of
the introduction of the distributed energy system, as well as optimizing the existing the distributed
energy system.
Next, HEATMAP, distributed energy system analysis software for steam, hot water and
chilled-water system has been introduced. It is a Microsoft Windows®-based software tool
developed by Washington State University. It is an easy-to-use software program that was
specifically developed to help plan, analyze, and operate distributed energy system.
Case study
In this part, at first, the distributed energy system at KSRP has been evaluated by using the
comprehensive evaluation system. Then the running mode and operating schedule of gas engine
system has been optimized by using HEATMAP. The influence of operating mode and schedule on
running effect of gas engine and the district energy system have been analyzed respectively.
Next, the viability of small-scale distributed energy system has been examined by analysis of a
case study in Kitakyushu. Four options combining gas-boiler and gas-turbine are evaluated
regarding energy efficiency, environmental load and economic efficiency. Finally, five cases with
various scales of housing complex and operating mode of distributed energy system have been
compared by using computer software, HEATMAP. Based on the above results, various cases have
been evaluated and compared regarding energy utilization efficiency and environmental effect and
economic efficiency. Furthermore, the influence of housing complex’s scale and system’s operating
mode on the introduction effect of distributed energy system was analyzed
