Abstract
A smart controller (102) receives, from an EMS (70), control information in the form of rate information indicating electricity prices determined in accordance both with supply of electricity from a power system (60) and with demand of electricity from a group of users. Additionally, on the basis of comparison of the electricity prices with rate threshold values found in a predetermined correspondence relationship between operation mode and rate threshold value, the smart controller (102) determines an operation mode for a rechargeable battery (108) in such a manner that, as the operation mode, an operation mode in which to discharge electricity is set when the electricity prices is high, and an operation mode in which to charge electricity is set when the electricity prices is low. Furthermore, the smart controller (102) controls the rechargeable battery (108) so that electricity may be charged or discharged in accordance with the thus determined operation mode.
