POWER SYSTEM DEMAND CONTROL EQUIPMENT, DEMAND CONTROL PROGRAM AND RECORDING MEDIUM

Title:

POWER SYSTEM DEMAND CONTROL EQUIPMENT, DEMAND CONTROL PROGRAM AND RECORDING MEDIUM

Document Type and Number:

WIPO Patent Application WO/2011/024769

Kind Code:

A1

Abstract:

An economic load distribution section (22) calculates a discharge threshold value and a charging threshold value based on the discharging unit cost and charging/discharging efficiency of a secondary battery (BT). The secondary battery (BT) is discharged if the incremental fuel cost of generators (G1 to Gn) is higher than the discharge threshold value. Alternatively, the secondary battery (BT) is charged if the incremental fuel cost of the generators (G1 to Gn) is lower than the charging threshold value. The respective output distributions of the generators (G1 to Gn) and the secondary battery (BT) are then calculated. Target instruction value generation sections (211 to 21n, 21BT) generate and output target instruction values for the generators (G1 to Gn) and the secondary battery (BT) in accordance with the output distributions which were calculated.
