Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing independent power supply systems struggle to appropriately adjust power supply and demand balance due to fixed storage batteries and adjustment loads, limiting effective power management.
Innovation Solution
A power adjustment device that sets target power devices for operation control based on predicted supply and demand balance, using a setting unit to identify and an adjustment unit to manage the operation of storage batteries and loads to balance power supply and demand.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If fixed storage batteries and adjustment loads are used in the independent power supply system, then the system structure is simple, but the power supply and demand balance cannot be appropriately adjusted
Solution Approach 1:
The patent applies the dynamics principle by enabling the power supply system to dynamically select and switch between multiple adjustment methods (storage battery charging/discharging control, load adjustment, and power generation control) based on real-time power supply and demand conditions. This allows the system to adapt to varying conditions while maintaining a relatively simple overall structure, resolving the contradiction between adaptability and device complexity.
Solution Approach 2:
The patent implements multi-functionality by designing a control device that can perform multiple adjustment functions using the same hardware components. The storage battery system can both store power and adjust demand, the load can both consume and adjust power consumption, and the power generator can both generate and control power output. This universal approach enhances adaptability without proportionally increasing device complexity.
2Quantity of substance
If the storage battery is charged beyond its maximum charge power or discharged beyond its maximum discharge power, then more power can be stored or released, but the system operation becomes unstable
Solution Approach 1:
The patent applies feedback control by continuously monitoring the charge and discharge status of the storage battery and adjusting the control commands accordingly. When the storage battery reaches its maximum charge or discharge power limits, the control device receives feedback and automatically adjusts the power supply and demand balance by switching to other adjustment methods, preventing overcharging or over-discharging and maintaining system stability while maximizing power storage capacity.
3Quantity of substance
If the adjustment load consumes more power, then the power demand can be increased, but the power supply and demand balance becomes harder to maintain
Solution Approach 1:
The patent implements self-service control by enabling the adjustment load to automatically respond to power supply and demand conditions. The control device monitors the current power balance and autonomously adjusts the load's power consumption without requiring manual intervention. This self-regulating mechanism allows the system to increase or decrease power consumption as needed while automatically maintaining the power supply and demand balance, resolving the contradiction between power quantity and ease of operation.

AI summary
The power supply and demand balance is appropriately adjusted. A power adjustment device 1 is a power adjustment device 1 that adjusts a power supply and demand balance in a power system including one or more power devices each of which is at least one of a storage battery and a load. The power adjustment device 1 includes a setting unit 13 that sets at least one of the power devices as a target power device, for which operation control related to power is possible, based on the supply and demand balance predicted and an adjustment unit 14 that adjusts the supply and demand balance by controlling an operation of the target power device.
