An energy operation system, apparatus, and method capable of stably supplying energy and providing adjustment control based on prediction precision and planning precision for energy supply and demand. An energy operation apparatus includes a demand predictor, planner, evaluator, and solution quality controller. The demand predictor predicts demand and/or a power generation amount of future energy in a management area. The planner prepares a future energy supply plan in the management area based on a prediction. The evaluator evaluates supply and/or demand conditions including at least one of future weather in the management area, energy demand in the management area, a demand density and/or a generation density of future energy in the management area. The solution quality controller controls the quality of at least one of a prediction solution of the demand predictor and the energy supply plan of the planner based on an evaluation result from the evaluator.

Energy operation apparatus, method, and system

An electric power demand adjustment program management apparatus, comprises a server which includes: a communication unit that communicates with a plurality of customer terminals that manage customer devices through a communication network; a program unit that creates an electric power demand adjustment program showing a demand adjustment amount allocated to at least one first customer terminal selected from the plurality of customer terminals in each predetermined time segment, based on predetermined constraint conditions and predetermined information received from the plurality of customer terminals; a program executing unit that transmits the electric power demand adjustment program, and instructs the first customer terminal to execute the electric power demand adjustment program; and a providing unit that provides, when the program unit fails to create the electric power demand adjustment program, investigation result information including an investigation result for a cause of the failure.
