PROBLEM TO BE SOLVED: To provide a power aggregator system capable of improving the profitability of a power aggregator, and to provide a power transaction method, and a power transaction program.SOLUTION: According to an embodiment, the power aggregator system includes a reduction information acquisition part, a DR signal reception part, a bid information calculation part, and an adjustment for electric power supplier part. The reduction information acquisition part acquires information of a reducible DR amount being a received power amount that can be reduced in each user. The DR signal reception part acquires information of a required DR amount being a received power amount which the electric power supplier requests the power aggregator to reduce. The bid information calculation part makes a selling bidding of a power amount in a negative watt transaction market in the case that surplus power occurs because a value obtained by totalizing reducible DR amounts of the user exceeds the required DR amount. The adjustment for electric power supplier part acquires amount information in accordance with a value obtained by totalizing user reduction DR amounts being actual values of each user of a power amount reduced by an apparatus of the user.SELECTED DRAWING: Figure 1 |
