POWER MANAGEMENT SYSTEM, POWER MANAGEMENT METHOD, AND COMPUTER PROGRAM

摘要

A power management system includes a first administrator, a second administrator, a first estimator, a second estimator and a determiner. The first administrator manages a residual capacity of a power storage apparatus. The second administrator manages interruption information regarding a power grid. The first estimator estimates, as first power information, an amount of power that is consumed by an electric load during an interruption period. The second estimator estimates an estimation residual capacity that is the residual capacity at an end point of the interruption period, based on the first power information. The determiner determines that a condition for participating in a power trade market is met, when the estimation residual capacity exceeds a reference value.

1. A power management system, comprising:
a first administrator configured to manage a residual capacity of a power storage apparatus; a second administrator configured to manage interruption information that includes an interruption period during which a power grid is in a service interruption state; a first estimator configured to estimate, as first power information, an amount of power that is consumed by an electric load during the interruption period; a second estimator configured to estimate, at a start point of the interruption period or before start of the interruption period, an estimation residual capacity based on the first power information, the estimation residual capacity being the residual capacity at an end point of the interruption period; and a determiner configured to determine that a condition for participating in a power trade market is met, when the estimation residual capacity exceeds a reference value, and to set an amount of power by which the estimation residual capacity exceeds the reference value, as an upper limit of a power selling amount in the power trade market.
