项目摘要

In this study, we firstly have investigated the situation of distributed energy resource (DER)in Japan and have a comparison with the other countries. Then, we try to establish the databases for building energy demand, tariffs of gas and electricity, and technology through a comparison study between Japan and the U.S. covering the policy, technology and the utility tariffs effects on DER systems installations.In the field study, we selected the energy center in Kitakyushu Science and Research Park(KSRP) as a case study and have carried out an analysis on the efficiency of the power generation and heat release utilization of the fuel cell and gas engine in summer by using recorded data. The results can be summarized as follows ; 1)Although the power generation efficiencies of the gas engine and fuel cell are slightly lower than the standard designated value, they are almost constant throughout the period of study. 2)The collected heat energy is lower than the designated value. The heat release utilization, which is used for cooling and hot water, is lower than expected 3)The discarded heat energy of the system is very big in this investigation when evaluating the system as a whole.The evaluation tools have been presented for energy conversation, environment, economics and the other effects due to the introduction of DER. By using those evaluation tools, a total evaluation of energy and CO2 discharge for KSRP has been carried. Furthermore, the viability of co-generation system in a small-scale house complex has been examined and the optimum design for the complex has been analisized by discussing the effects of house complex scale, running mode. Finally, the effects on local environment due to the introduction of DER have been simulated.

在本研究中，我们首先调查了日本的分布式能源（DER）的情况，并与其他国家进行了比较。然后，通过对日本和美国的政策、技术和公用事业电价对DER系统安装的影响的比较研究，试图建立建筑能源需求、天然气和电力关税和技术的数据库。在实地研究中，我们选择了北九州科学研究园区能源中心作为案例研究，利用记录数据对燃料电池和燃气发动机在夏季的发电效率和放热利用进行了分析。研究结果总结如下：1)虽然燃气发动机和燃料电池的发电效率略低于标准指定值，但在整个研究过程中几乎是恒定的。2)收集的热能低于规定值。用于冷却和热水的放热利用率低于预期。3)在对整个系统进行评估时，本研究中系统的废弃热能很大。已经提出了能源节约、环境、经济和其他影响的评估工具。利用这些评价工具，对KSRP的能量和CO2排放量进行了综合评价。在此基础上，考察了小型住宅小区热电联产系统的可行性，并通过讨论住宅小区规模、运行方式等因素对热电联产系统的优化设计进行了分析。最后，模拟了DER的引入对局部环境的影响。
