Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing power management systems are ineffective in utilizing power generated at regionally distributed facilities such as solar panels, as they primarily rely on storage at centralized power plants, failing to efficiently integrate and utilize distributed energy sources.
Innovation Solution
A power management system comprising a holding unit for storing energy, a supply unit for procuring power from contractors, and a setting unit that determines the utilizable range of stored energy, allowing excess energy to be utilized when it exceeds a predetermined amount, enabling the system to effectively manage and distribute power generated at distributed facilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If power is stored only at centralized power plants, then storage reliability is improved, but power utilization efficiency deteriorates
Solution Approach 1:
The patent segments the centralized power storage system into distributed storage units located at multiple power generation facilities throughout the region. Each facility stores power locally in its vicinity, transforming the single centralized storage location into multiple distributed storage nodes. This segmentation enables both reliable storage at each node and efficient utilization by reducing transmission distances and enabling local power exchange among facilities.
2Productivity
If power is stored at regionally distributed facilities, then power utilization efficiency is improved, but system complexity increases
Solution Approach 1:
The patent implements a universal power management system that performs multiple functions: it manages power storage at distributed facilities, facilitates power exchange between facilities, controls power transmission routes, and monitors system status. This multi-functional system handles the complexity of distributed management through a unified control framework, enabling efficient power utilization without proportionally increasing system complexity.
Solution Approach 2:
The patent introduces a power management system as an intermediary that coordinates between distributed power generation facilities and the power transmission network. This intermediary handles the complexity of managing multiple distributed storage units by providing centralized control functions, including determining power transmission routes and controlling power flow, thereby simplifying the overall system architecture.
3Loss of energy
If excess storable energy is utilized, then energy waste is reduced, but power supply stability deteriorates
Solution Approach 1:
The patent implements dynamic adjustment of the utilizable range of storable energy based on real-time power supply and demand conditions. The power management system continuously monitors the status of power generation facilities and transmission lines, and dynamically determines the appropriate amount of excess energy to utilize. This dynamic approach allows the system to maximize energy utilization while maintaining power supply stability by adjusting utilization levels according to current system conditions.

AI summary
A power management system, which has a holding function capable of holding power in the form of storable energy, and a supply function for supplying power procured from a contractor to the holding function, sets a utilizable range of storable energy held by the holding function. In the setting, if an amount of storable energy held by the holding function exceeds a predetermined amount, an excess of the storable energy exceeding the predetermined amount is set as utilizable storable energy.
