POWER ADJUSTMENT DEVICE, POWER ADJUSTMENT METHOD, AND PROGRAM

摘要

The objective is to increase a profit to be earned by a person of a customer facility without need of forecasting a price in an electricity market when the customer facility including a power supply apparatus supplies power to a power grid. The power adjustment system (10) includes a first estimator (11), a second estimator (12), a calculator (13), a controller (14), and a determiner (15). The first estimator (11) estimates power to be consumed by an electric load (2) during an interested period. The second estimator (12) estimates power obtainable from a power supply apparatus (20) during the interested period. The calculator (13) determines a profit in the interested period by calculating a difference between income and a cost. The controller (14) selects one of a first state of supplying power from a power storage apparatus (21) to a power grid (30) and a second state of supplying power from the power storage apparatus (21) to the electric load (2). The determiner (15) provides an instruction to the controller (14) so as to maximize the profit in the interested period.
