Storage battery management system

摘要

A power receiving unit receives power generated by power generating units via a power system. A power information acquiring unit acquires first system power information showing the proportion of power generated by each power generating unit in a first period. An intensity database stores environmental loading intensities for each power generating unit. A charge load intensity calculator calculates a charge load intensity which is a weighted sum of the environmental loading intensity corresponding to each power generating unit based on the proportion of each power generating unit in the first system power information. A charge/discharge judging unit determines to charge a storage unit in a first period when the charge load intensity is less than a reference value, and not to charge the storage unit in the other cases. A charge/discharge controller charges the storage unit in the first period when determined to charge the storage unit.

主权项

1. A storage battery management system, comprising:
a power receiving unit configured to receive power generated by a plurality of power generating units via a power system; a power information acquiring unit configured to acquire first system power information showing a proportion of power generated by each power generating unit in a first period; an intensity database configured to store environmental loading intensities indicating each an amount of environmental load emitted by each power generating unit per unit electric energy; a charge load intensity calculator configured to calculate a charge load intensity which is a weighted sum of the environmental loading intensities corresponding to each power generating unit by the proportion of each power generating unit shown in the first system power information; a storage unit configured to be capable of charging/discharging power; a charge/discharge judging unit configured to determine to charge the storage unit in the first period when the charge load intensity is less than a reference value, and to determine not to charge the storage unit in the first period when the charge load intensity is equal to or greater than the reference value; and a charge/discharge controller configured to charge the storage unit in the first period by using the power received by the power receiving unit, when the charge/discharge judging unit determines to charge the storage unit.
