Electric power supply-and-demand control system, electric power management apparatus, and electric power supply-and-demand control method

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.

1. An electric power supply-and-demand control system capable of transmitting/receiving data to/from a power management apparatus provided to each of consumers to instruct the power management apparatus to adjust electric power, the system comprising:
a memory unit to memorize a supply, consumptions, reserve power, and response results, the supply showing a total of electric power supplied to the consumers, the consumptions showing electric-power consumptions of the consumers, the reserve power showing a range of electric power adjustable for each of the consumers, the response results showing a time needed for the consumers to have reached a first adjustment amount previously, an estimation unit to estimate a response speed on the basis of the response results; a first calculation unit to calculate a target value allowing it to eliminate an unbalance between the supply and a demand, the demand being given as a total of the consumptions; and a second calculation unit to calculate second adjustment amounts so that a total of the second adjustment amounts approaches the target value and is in the range.
