Abstract: A retention amount management system includes a detector that detects an amount of retention and a server that adjusts an amount of production of hydrogen in a production facility such that the amount of retention of hydrogen retained in a retention facility for a predetermined period attains to a target amount of retention. The server sets the target amount of retention such that an amount of hydrogen ? corresponding to an amount of surplus electric power during a preparation period during which electric power generated per prescribed period by using renewable energy is higher than a threshold value is larger than an amount of hydrogen ? corresponding to the amount of surplus electric power during an ordinary period.

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.

Abstract: A server that manages energy of a power grid by using a plurality of energy storage resources includes a loss obtaining unit and a selector. The loss obtaining unit obtains for each of the plurality of energy storage resources, energy loss including retention loss and input and output loss, the energy loss being caused in storing energy in each energy storage resource. When surplus electric power occurs in the power grid, the selector selects at least one energy storage resource for storing surplus electric power from among the plurality of energy storage resources based on the energy loss caused in storing surplus electric power.

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.

The server sets the target amount of retention such that a first amount of hydrogen a corresponding to an amount of surplus electric power during a stable period during which electric power generated per prescribed period by using renewable energy is higher than a threshold value is larger than a second amount of hydrogen ? corresponding to the amount of surplus electric power during an ordinary period.

Abstract: The number of opportunities where external charging of a vehicle parked in a residential parking space or a charging station in a predetermined period is available is counted as the number of opportunities, and the number of times of the external charging performed in the opportunities in the same predetermined period is counted as the number of times of charging. The number of times of charging is then divided by the number of opportunities to calculate and store a charging frequency. Since the charging frequency is a ratio of the number of times that the external charging was performed to the number of opportunities where the external charging is available in the predetermined period, the ratio is used as an index that can offer more accurate determination regarding an external charging utilization status. As a result, various processing to promote external charging are executed more properly.
