Securing Energy during Power Outage

If distributed power such as gas CHP is utilized, essential buildings in a community, such as hospitals and commercial facilities do not lose their functions even in a power outage.

 

Maintaining supply of electricity by the islanded operation of gas CHP


As the Smart Energy Network uses gas CHP, which is distributed power, electricity supply will continue during a power outage. During normal operation, the area within the Smart Energy Network receives the electric power both from electric utilities and from power generation by gas CHP. In case of a power outage, the gas CHP starts to supply electric power to the area covered by the Smart Energy Network by its islanded operation.

Maintaining supply of electricity at disaster-prevention centers through the Smart Energy Network


Electric and thermal energy supplied by the islanded operation of gas CHP during an unexpected power outage can be mutually accommodated within the Smart Energy Network area.
Also, a group of power-generating devices is operated using Information Communication Technology (ICT) to achieve a highly reliable electric power supply system.
By making essential facilities such as hospitals and train stations more disaster-proof from the point of view of energy, our community can be more energy-secure.
