POWER MANAGEMENT SYSTEM FOR EACH DWELLING OF COLLECTIVE HOUSING EMPLOYING VIRTUAL POWER STORAGE SECONDARY BATTERY, AND POWER FEE CHARGING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a power management system and a power fee charging method which enable each dweller to easily enjoy merits of power saving in power supply in which a large-capacity secondary battery such as an NAS battery and a Zebra battery are arranged in a collective housing as emergency power sources and the leveling of a power load, in a high-technology collective housing where dwellings have Internet-connected power meters.

SOLUTION: In the power management system and the power fee charging method, it is assumed that a virtual battery is installed in one dwelling of the collective housing, and the virtual charging and discharging of the virtual battery is utilized for the power management of the one dwelling. The system is provided with a means for calculating the capacity of the virtual battery on the basis of data of a power consumption change database, a means for calculating a time band of charging the virtual battery on the basis of the data of the power consumption change database, and a means for calculating a time band of discharging the virtual battery on the basis of the data of the power consumption change database.
