Title:
電力需要調整システムおよびその方法
Document Type and Number:
Japanese Patent JP7011991
Kind Code:
B2
Abstract:
To provide a power demand adjustment system which reduces supply insecurity by peak cutting in a power system.SOLUTION: A power demand adjustment system includes multiple batteries 4 connected with a power system 1, and a power demand adjustment server 6 imparting a demand adjustment control command for charging and discharging appropriately to the batteries 4 for peak cut. The server 6 includes a profile processing part 11 generating profile information, indicating power demand suppression effect, for each battery 4 with the finite difference of normal time power demand information and control time power demand information at each time as peak cut capability, and a control pattern generation part 13 generating a control pattern based on combination of multiple pieces of profile information for determining power demand control amount at a prescribed time of peak cut. In the demand adjustment control command based on its control pattern, the multiple batteries 4 are selected and controlled. The power demand adding the multiple pieces of profile information to the normal time power demand information is restrained below a specified value in a prescribed time band.SELECTED DRAWING: Figure 1
