System Configuration-- Small-scale Distributed Power Generation System --

  • Advantages of this technology
    • Gasification at lower temperature (650℃)→Higher efficiency
    • Combustion of generation gas in GT leads to no requirement for tar removal
    • Higher efficiency by exhaust gas recirculating system

slide11

Grid-Interconnection of Clustered Photovoltaic Power Generation Systems

1. Development of technology to avoid output restrictions:

To develop and verify technology to avoid PV output restrictions caused by excess voltage on distribution lines occurring from surplus PV output.

2. Demonstrative project of technologies required to resolve the effects in higher harmonics:

To develop technologies required to resolve the effects of higher harmonics resulting when distribution lines and PV systems are interconnected.

3. Demonstrative project of technologies to develop new types of islanding prevention devices:

To develop new types of islanding prevention devices to halt unintentional islanding when a large number of PV systems are interconnected to the distribution lines.

4. Development of advanced simulation methods:

To develop methods to simulate concentrated connections of many PV systems interconnected to a single distribution line.

Hydrogen Codes/Standards

Two-year review of 28 codes in 6 laws completed in March 2005. Roadmap for compliance/modifications developed.

  • Required inert gas purging when the PEFC system was shut down; No space around Japanese homes for inert gas set.
  • Required 3m isolation distance between the system and house perimeter. Japanese-sized lots could not accommodate required isolation.
  • Necessary that Electrical Safety Administrator always observed the PEFC system in the house. Occupants would have had to have been certified.
  • Necessary to notify regional fire authorities of installation of PEFC systems.

Demonstration of Residential PEFC Systems

  • More than 400 PEFC systems will be installed into residential buildings, with a subsidy of 6m Yen (~US$50,000) per system in 2005.
  • Tokyo Gas: For ~$90,000, Tokyo gas will lease a 1 kW PEFC cogeneration system and maintain all residential gas equipment for ten years and collect operating data.
  • Aim: to create an initial market for mass production and cost reduction. (Chicken and egg)
  • Increase number of installed systems and gradually decrease subsidy in 2006 & 2007.
  • Budget: 2.5B Yen (US$22M)/year for three years (2005-2007).
