Abstract
A system operator side computer includes: a supply amount acquirer configured to acquire a maximum suppliable power amount from a power generation operator at a predetermined time later; a demand specifier configured to specify a power demand at the predetermined time later; and a shortage amount calculator configured to calculate a power shortage amount based on the power demand and the maximum suppliable power amount.
Claims11
An operator side power supply manager device, comprising:
- a memory storing computer-readable instructions;
- and
- a processor, coupled to the memory, the processor configured to execute the computer-readable instructions to:
- apply a first power amount to a load using a weather dependent power supply device;
- apply a second power amount to a load using a weather independent power supply device;
- receive weather information over a network;
- predict the first amount of power applied to the load by the weather dependent power supply device at a predetermined time based on the received weather information;
- determine a total power amount comprising a sum of the predicted first amount of power applied to the load by the weather dependent power supply device at the predetermined time based on the received weather information and a second amount of power applied to the load at the predetermined time by the weather independent power supply device;
- determine whether the total power amount applied to the load at the predetermined time is insufficient to meet a power demand of the load at the predetermined time;
- when the total power amount is determined to be insufficient at the predetermined time, determine an increase to the second amount of power to apply to the load at the predetermined time by the weather independent power supply device to meet the power demand of the load;
- and
- apply the increase to the load at the predetermined time.
