Abstract: Upon receipt of a reported value (an amount of power generation by a renewable energy facility) in a time slot from an agent of a prosumer (facility), a processor of a transaction market server calculates a predicted amount of power generation of the renewable energy facility in the time slot (S1 to S13). The processor sets a first threshold for the predicted amount of power generation and determines a normal range of the reported value (S15). The processor compares the reported value with the predicted amount of power generation, and when the reported value is outside the normal range, prohibits the facility with the renewable energy facility from using a renewable energy tag.

Abstract: An agent is an information processing apparatus that puts in a bid to allow a vehicle to conduct transaction of power reception/provision through a transaction market server. In the event of nonfulfillment of transaction which means that the vehicle does not conduct transaction of power reception/provision, the transaction market server performs penalty processing for imposing a penalty on a user of the vehicle. The agent includes a bid processing unit and an indicator value calculator. The bid processing unit is configured to put in a bid to the transaction market server. The indicator value calculator calculates an indicator value that represents an extent of the penalty imposed on the user in the penalty processing. When the indicator value reaches a threshold value, the bid processing unit suspends a bid.
