Cooperation in supply and demand balance of renewable energy in a region is implemented by operation of infrastructures of an infrastructure service such as water supply.

In an energy management system including: a processor; and a storage device, the processor predicts an electric power supply amount utilizing renewable energy in a predetermined region, predicts an electric power demand amount in the region, predicts a demand amount of an infrastructure service different from an electric power service in the region, predicts an electric power demand amount corresponding to the infrastructure service on the basis of the predicted demand amount of the infrastructure service in the region, and determines use time of electric power corresponding to the infrastructure service such that the electric power demand amount in the region approaches the electric power supply amount.

An industrial vehicle charging system includes a plurality of chargers, a charge controller configured to instruct each of the plurality of the chargers on a value of charge power, and a management device configured to receive charge information of an industrial vehicle. The chargers each have a communication unit that receives the charge information, and transmits the charge information to the charge controller. The management device has a storage that stores a charge schedule and an operation load, and a required charge amount calculator that calculates a required charge amount of the industrial vehicle The charge controller has a charge power value calculator that calculates the value of the charge power which is transmitted to each of the chargers.

A power management system includes a plurality of power storages and a server. The server includes a selector that selects at least one of the plurality of power storages, a scheduler that makes a schedule for the selected power storage, and a request processor that requests a user of the selected power storage to control at least one of external charging and external power feed in accordance with the made schedule. The server obtains desire information that indicates a desire level (priority on battery life/priority on an incentive) and carries out at least one of selection of the power storage and making of the schedule based on the obtained desire information.

A modular power supply and distribution system includes a controller and at least one power distribution bus operably connected to the controller. The system includes at least one power distribution bus that distributes electrical power to a plurality of loads. The system further includes a data communication network configured to communicate data between the system and the plurality of loads, power load logic for determining a power load requirement of each of the plurality of loads, hold-up logic for determining a hold-up requirement of at least one of the plurality of loads; and power distribution logic for distributing the electrical power to the plurality of loads based, at least in part, on the determined power load requirement of each of the plurality of loads and the hold-up requirement of the at least one of the plurality of loads.
