    Abstract: A server notifies a user of a vehicle that is able to participate in DR. The server includes a communication device and a processing device. The communication device communicates with a provider server that stores information indicating an execution period and an execution location of at least one job given by a provider. The processing device performs a process of inquiring the provider server about whether the at least one job includes a target job through the communication device. The target job is a job of which the execution period is included in a DR period and the execution location is in a vicinity area of a DR location. When the at least one job includes the target job, the processing device performs a notification process of notifying the user of target job information indicating the execution period and the execution location of the target job.

  • Publication number: 20220396170
    Abstract: A power management system includes a plurality of power adjustment resources electrically connected to a microgrid MG, and a CEMS server that manages the power adjustment resources. The CEMS server outputs a power adjustment request to a plurality of power adjustment resources when suppression of power consumption or consumption of surplus power is requested in the microgrid MG, and gives an incentive to the power adjustment resource that performs power adjustment in response to the power adjustment request among the power adjustment resources. The CEMS server increases the incentive more as a deviation of a second power amount adjusted by a responding resource with respect to a first power amount requested for adjustment by the power adjustment request is smaller.

  • Publication number: 20220396171
    Abstract: A power management system includes a plurality of power adjustment resources electrically connected to a microgrid MG, and a CEMS server that manages the power adjustment resources. The CEMS server outputs a power adjustment request to the power adjustment resources when suppression of power consumption or consumption of surplus power in the microgrid MG is requested, and gives an incentive to a “responding resource” as the power adjustment resource that performs power adjustment in response to the power adjustment request among the power adjustment resources. The CEMS server increases the incentive more as a deviation of a time period during which the power adjustment is performed by the responding resource, with respect to a time period determined in the power adjustment request is smaller.

  • Publication number: 20220246955
    Abstract: A CEMS server obtains meteorological information and hydrogen station information. The CEMS server predicts a power demand of a microgrid after a designated period. When the power demand of the microgrid after the designated period exceeds contract power and when an amount of electric power to be reduced exceeds a prescribed value, the CEMS server generates a hydrogen addition notification and transmits the generated hydrogen addition notification to an FCEV and/or a communication terminal. The amount of electric power to be reduced is a difference between the contract power and the power demand.

  • Publication number: 20220242271
    Abstract: A controller of an EMS server determines whether it has received a supply and demand request from a power transmission and distribution utility server. When having received the supply and demand request, the controller determines whether the supply and demand request is for requesting an increase in power demand or for requesting an increase in power demand. The controller decomposes the supply and demand request into first to third requests. The controller creates a negawatt DR execution plan or a posiwatt DR execution plan based on a determination result of S3. The controller allocates power adjustment resources to the first to third requests in consideration of responsiveness of each of the power adjustment resources. The controller transmits the first to third request signals to target power adjustment resources in accordance with the execution plan.
