POWER MANAGEMENT DEVICE, POWER MANAGEMENT METHOD, AND PROGRAM

摘要

An object is to provide a motivation for promoting use of a power storage apparatus. A power management system (10) includes a receiver (11), an estimator (12), an administrator (13) and a determiner (14). The receiver (11) acquires DR information that includes a reduction value and a target period for requesting a reduction of received power. The estimator (12) estimates, as first power information, power that is consumed by an electric load (2) during the target period. The administrator (13) manages, as second power information, power that can be output from a power supplying apparatus (20) including a power storage apparatus (21). The determiner (14) determines that a condition for participating in a power trade market is met, when determining that the reduction value is achievable during the target period, based on the first power information and the second power information.
