POWER LOAD LEVELING METHOD, POWER LOAD LEVELING SYSTEM, POWER RATE DECISION METHOD AND POWER RATE DECISION SYSTEM

摘要

PPROBLEM TO BE SOLVED: To provide a power load leveling method that can reliably level a power load while easily responding to a short-term power load fluctuation. PSOLUTION: Under pressure on power involving an unexpected power demand-supply balance, a power rate discount or another privilege is given to power consumers as a motivation to reduce power consumption below contracted power on a spot basis, so that the power load can be leveled. IT equipment is used to provide an environment wherein the power consumers can offer power consumption reduction or additional purchase and the power consumers and a power supplier can exchange information in two ways with little time delay. The environment is configured with disclosure, and under the environment, each power consumer views a disclosed power demand-supply status and correspondingly presents reducible or additionally purchasable power and a time zone thereof. The power supplier can carry out the process not solely but through two-way communication with the power consumers. PCOPYRIGHT: (C)2005,JPO&NCIPI
