| Research Abstract |
This paper aims hybrid utilization of renewable energy and the fuel cell for a residential energy system. The following results were obtained.
(1)Three kinds of experiments applied typical electric power and hot water demands were carried out. The primary energy reduction rate of the double DSS operation to a conventional system reached 24%.
(2)The amount of the primary energy reduction in Sapporo surpassed the experimental results for the standard energy demands. Therefore, it was clarified that this system has & high degree of feasibility in the cold region.
(3)As a result of simulations on the grid-connected fuel cell cogeneration system without the reverse power flow, the optimum capacity of the fuel cell ranged from 0.8kW to 0.9kW. It is possible to miniaturize the fuel cell capacity, when the reverse power flow is accepted.
(4)Numerical simulations on detached homes, a micro-grid network system and a central system were carried out m order to reduce a reverse power flow of a grid-connected decentralized energy system and optimize the grid-connected fuel cell cogeneration system.
(5)The amount of hydrogen absorbing alloys for residential electric and heat demand was calculated. And the evaluation on the primary energy reduction rate of the system was carried out.
