    Abstract: 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.

  • Patent number: 10600135
    Abstract: To minimize the amount of calculation for changing an operation schedule even when there is an increase in the number of sites. A management computer calculates a first total schedule value, which is the total of the schedule values for each of the sites within a first time frame. If the first total schedule value exceeds a first target value set in advance, the management computer: calculates a first excess amount of the first total schedule value in relation to the first target value; selects, as a first site, a site subjected to a change in a demand schedule from a group of candidate sites satisfying a candidate criterion set in advance from among a plurality of the sites, the selection being performed on the basis of information on the facility characteristics for each of the sites; changes a first demand schedule of the first site in the first time frame; and transmits the changed first demand schedule to a control device of the first site.

  • Publication number: 20190130423
    Abstract: To solve such a problem, demand categories are prepared. ‘Demand categories’ are units of classification for demand. Where the demand included in the ‘demand categories’ is concerned, any attribute such as the contract type, industry type, demand location, and demand generation period constitute the same demand. For example, a management apparatus comprises a sales income calculation unit which calculates sales income derived from supplying demand by using a time interval-differentiated fee unit price for each demand category and a power usage value, an earnings prediction spread calculation unit which compares earnings for each of a plurality of future volume estimation time series relating to power usage volumes of predetermined periods of the demand categories, and a fee unit price search unit which searches for a fee unit price satisfying a limiting condition based on a comparison result.
