Techniques are presented for scheduling the charging of electric vehicles (EVs) that protect the resources of local low voltage distribution networks. From utilities, data on local low voltage distribution networks, such as the rating of a distribution transformer through which a group of EVs are supplied, is provided to a load manager application. Telematics information on vehicle usage is provided from the EVs, such as by way of the original equipment manufacturer. From these data, the load manager application determines schedules for charging the group of EVs through a shared low voltage distribution network so that the capabilities of the local low voltage distribution network are not exceeded while meeting the needs of the EV user. Charging schedules are then transmitted to the on-board control systems of the EVs for implementation.

A method of providing power, via a plurality of power control systems, includes forming, by at least two power control systems from among the plurality of power control systems, a power network and defining, by each power control system of the power network, a power allocation schedule for a power cycle using a dynamic load scheduling model. The power allocation schedule identifies one or more designated power control systems from among the at least two of the power control systems to provide power to a load during the power cycle. For at least portion of the power cycle, the method includes providing power to the load by the one or more designated power control systems of the power network based on the power allocation schedule.

A computer manages a plurality of resources operable as a balancing power for an external power supply. Each of the resources includes a power storage device chargeable with electric power from the external power supply. The computer executes resource selection for selecting a resource to be operated as the balancing power from among the resources in response to a charging request for the balancing power. The computer determines chargeable periods of the resources prior to the resource selection. The computer selects a resource having a short chargeable period with priority in the resource selection in response to a first charging request, and selects a resource having a long chargeable period with priority in the resource selection in response to a second charging request. A balancing period requested in the second charging request is longer than a balancing period requested in the first charging request.

In a controller, memories store device status data indicating an operation status of an electrical device, and measurement value data indicating an actual achieved value of a power consumption amount of the electrical device.
