Abstract: 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.

Abstract: The power adjustment system includes a first estimator, a second estimator, a calculator, a controller, and a determiner. The first estimator estimates power to be consumed by an electric load during an interested period. The second estimator estimates power obtainable from a power supply apparatus during the interested period. The calculator determines a profit in the interested period by calculating a difference between income and a cost. The controller selects one of a first state of supplying power from a power storage apparatus to a power grid and a second state of supplying power from the power storage apparatus to the electric load. The determiner provides an instruction to the controller so as to maximize the profit in the interested period.

Abstract: A first estimator estimates first power to be generated by a photovoltaic power generation apparatus during an interested period. A second estimator estimates second power to be consumed by an electric load during the interested period. A power purchasing cost calculator calculates, when there is a shortfall in the first power compared to the second power, a cost to be paid for receiving, from a power grid, power for compensating for the shortfall. A determiner compares an amount of money to be paid to a customer facility in accordance with a trading term when power is supplied from the power storage apparatus to the power grid, with the cost calculated by the power purchasing cost calculator. A controller causes the power storage apparatus to the electric load when the cost to be paid to the customer facility is equal to or less than the cost.

Abstract: A power management system includes a receiver, an estimator, an administrator and a determiner. The receiver acquires DR information that includes a reduction value and a target period for requesting a reduction of received power. The estimator estimates, as first power information, power that is consumed by an electric load during the target period. The administrator manages, as second power information, power that can be output from a power supplying apparatus including a power storage apparatus. The determiner 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.
