NETWORK SYSTEM

摘要

According to one aspect of a network system according to the embodiments of the present invention, the network system comprises an energy demand/supply unit which receives energy and at least one unit selected from energy management units which supply energy to the energy demand/supply unit. The amount of energy used or energy charged by the energy demand/supply unit can be controlled. The amount of energy used or energy charged when the unit is controlled on the basis of at least the information relating to the energy charged can be smaller than the amount of energy used or energy charged when the unit is not controlled on the basis of at least the information relating to the energy charged. The energy demand/supply unit comprises one or more components which can operate in a plurality of spaces defined inside or outside the energy demand/supply unit, and which consume energy. The components selectively operate in at least a portion of the plurality of spaces, in accordance with whether the information relating to the energy charged is high-cost information.
