Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Power storage devices in different power supply areas face issues of power shortage and underutilization due to varying load frequencies and power consumption patterns, leading to inefficient power distribution.
Innovation Solution
A power storage amount control device and method that adjusts the target power storage amounts of individual power storage devices based on predicted power consumption, ensuring higher storage for areas with higher predicted consumption and utilizing surplus power where available, while minimizing underutilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If uniform power storage amount is set for all power storage devices, then device complexity is reduced and ease of operation is improved, but power shortage occurs in high-demand areas and underutilization occurs in low-demand areas
Solution Approach 1:
The patent applies local quality by setting different target power storage amounts for power storage devices based on their respective power supply areas' characteristics. The control device determines area-specific parameters (traffic volume, power consumption, load frequency) and sets customized target storage amounts, ensuring each area receives appropriate power supply without uniform constraints.
2Reliability
If higher power storage amount is set for all power storage devices, then power shortage is prevented, but underutilization of power occurs in low-demand areas leading to energy waste
Solution Approach 1:
The patent applies parameter changes by dynamically adjusting the target power storage amount parameter based on area-specific conditions. The control device calculates different target storage amounts using parameters such as traffic volume, power consumption, and load frequency, allowing optimization of power distribution without uniform over-provisioning.
3Loss of energy
If lower power storage amount is set for all power storage devices, then energy waste is reduced, but power shortage occurs in high-demand areas
Solution Approach 1:
The patent applies local quality by recognizing that different power supply areas have different power consumption characteristics and setting customized target storage amounts accordingly. High-demand areas receive higher target storage amounts while low-demand areas receive lower amounts, preventing both power shortage and energy waste through localized optimization.

AI summary
A power storage amount control device includes a processor configured to acquire a value of a parameter representing a predicted power consumption amount of a load, set target power storage amounts of a plurality of power storage devices based on the value of the parameter representing the predicted power consumption amount, transmit a signal to the power storage device such that the power storage amount of the power storage device is equal to or larger than the set target power storage amount, and set the target power storage amount of a first power storage device supplying the power to a first load higher than the target power storage amount of a second power storage device supplying the power to a second load of which the predicted power consumption amount is smaller than that of the first load.
