Power management system, server, and method of adjusting power demand and supply

A server configured to manage a plurality of power adjustment resources for use in adjusting supply power from a power system to a power network, the server comprising:

• a processor;
• and
• a memory that stores a program executable by the processor,
• wherein the processor is configured to
• output a power adjustment request to the power adjustment resources when suppression of power consumption or consumption of surplus power in the power network is requested, wherein:
• the power adjustment resources include a responding resource that is configured to perform the power adjustment in response to the power adjustment request, and
• the responding resource is configured to set an allowable range regarding the range to which the power adjustment is allowed and perform the power adjustment within the allowable range;
• and
• the processor is further configured to
• give an incentive to the responding resource, and
• increase the incentive more as a deviation of a second power amount adjusted by the responding resource with respect to a first power amount requested for adjustment by the power adjustment request is smaller.

A method of adjusting power demand and supply that manages a plurality of power adjustment resources for use in adjusting supply power from a power system to a power network, the method comprising:

• outputting a power adjustment request to the power adjustment resources when suppression of power consumption or consumption of surplus power in the power network is requested;
• wherein:
• the power adjustment resources include a responding resource that is configured to perform the power adjustment in response to the power adjustment request, and
• the responding resource is configured to set an allowable range regarding the range to which the power adjustment is allowed and perform the power adjustment within the allowable range;
• giving an incentive to the responding resource;
• and
• increasing the incentive more as a deviation of a second power amount adjusted by the responding resource with respect to a first power amount requested for adjustment by the power adjustment request is smaller.
