Document Type and Number:
Japanese Patent JP7113716
Kind Code:
B2
Abstract:
To provide a technology capable of easily grasping an economic balance on the basis of a storage battery retrofitted to a power generation system.SOLUTION: A power management device 50 for managing power in a power generation system including an existing power generation device, a retrofitted storage battery, and a power load device, includes: a pattern acquisition unit 51 for acquiring in advance a charge and discharge pattern of the retrofitted storage battery; and a balance acquisition unit 53 for acquiring an economic balance in consideration of a retrofitted storage battery. The balance acquisition unit 53 calculates a first economic value by multiplying a purchase price of system power from a power system by storage capacity of the retrofitted storage battery in a discharge period. During a charging period, by calculating a second economic value by multiplying the selling price of the generated power generated by the existing power generation device and the storage capacity of the retrofitted storage battery, the economic balance considering the retrofitted storage battery is obtained.SELECTED DRAWING: Figure 2
