ELECTRIC POWER INTERCHANGE SYSTEM

摘要

In a power interchange system, an electric power generated by a power generation device is interchanged between power consuming dwellings in a multi-family house. Each power consuming dwelling generates the power by using the power generation device and receives a commercial AC power supply via a shared power supply wiring. The amount of electric power supplied to each power consuming dwelling is managed by a power management device. The power management device manages a surplus power amount of one power consuming dwelling and a required electric power amount of another power consuming dwelling and supplies the surplus power from the former power consuming dwelling to the latter power consuming dwelling via the power supply wiring.
