摘要:
An electric power supply-and-demand control system includes a memory unit, an estimation unit, a first calculation unit, and a second calculation unit. The system is capable of transmitting/receiving data to/from a power management apparatus provided to each of consumers to instruct a power management apparatus to adjust electric power. The memory unit memorizes a supply, consumptions, reserve power, and response results. The estimation unit estimates a response speed on the basis of the response results. The first calculation unit calculates a target value which allows it to eliminate an unbalance between the supply and a demand. The demand is given as a total of the consumptions. The second calculation unit calculates second adjustment amounts so that a total of the second adjustment amounts approaches the target value and is in the range.

A first predicting unit predicts a power demand required by each customer. A first reliability value calculator calculates the reliability value of the predictive power demand for each customer. Predicted power supply from a power system is calculated with respect to each power generating unit. A second reliability value calculator calculates the reliability value of the predictive power supply for each power generating unit. A balancing unit obtains a supply-demand margin level based on the difference between: a first weighted sum obtained by performing weighted sum on the predictive power demand and a weight depending on the reliability value; and a second weighted sum obtained by performing weighted sum on the predictive power supply and a weight depending on the reliability value. A plan creator creates a plan for controlling power used by the controllable appliance of the customer based on the supply-demand margin level.
