Distributed Power Interchange for Surplus Energy in Visit Spaces
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing power management systems lack the capability to efficiently manage and utilize surplus power generated from distributed power supplies, such as solar cell devices, when users are present in visit spaces outside the facility where the power supply is located.
Innovation Solution
A power management apparatus and method that includes a management unit to track output power from a distributed power supply, a detection unit to identify when a user with the power supply is in a visit space, and a control unit to perform interchange processing, allowing the surplus power to be provided to the visit space based on the output power data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If a distributed power supply is installed in a predetermined facility, then power generation capability is improved, but the ability to utilize power in visit spaces is insufficient
Solution Approach 1:
The power management apparatus enables the distributed power supply to serve multiple functions: generating power at the predetermined facility and providing power to visit spaces through portable terminals. The system allows the same power generation source to benefit both the host facility and visiting users, transforming a single-location power supply into a multi-location power solution.
Solution Approach 2:
A portable terminal acts as an intermediary between the distributed power supply at the predetermined facility and the visit spaces. The terminal receives power data from the facility, stores it locally, and enables power utilization in visit spaces without requiring direct physical connection to the original power supply, thus bridging the spatial gap.
2Device complexity
If power data is managed only at the predetermined facility, then data management is simplified, but power interchange in visit spaces cannot be performed
Solution Approach 1:
The power management system is segmented into multiple independent components: the power management apparatus at the predetermined facility, portable terminals carried by users, and visit space infrastructure. Each segment can operate semi-independently, with the portable terminal serving as a mobile data management node that enables power interchange without requiring centralized control at the original facility.
Solution Approach 2:
The system transitions from two-dimensional spatial management (power supply at facility location) to three-dimensional management by adding the temporal and mobile dimension through portable terminals. Power data can be stored, transferred, and utilized across different locations and times, enabling power interchange in visit spaces without expanding physical infrastructure.
3Device complexity
If no detection mechanism is implemented, then system complexity is reduced, but user presence in visit spaces cannot be identified
Solution Approach 1:
The portable terminal performs self-service detection by automatically identifying when the user carrying it is present in a visit space. The terminal uses its own resources (sensor, processor, communication module) to detect presence and initiate power interchange operations without requiring external detection infrastructure at the visit space, thus minimizing system complexity while capturing necessary information.
Data Source
AI summary
A power management apparatus includes a management unit configured to manage data of output power output from a distributed power supply provided in a predetermined facility, a detection unit configured to detect that a user having the distributed power supply is present in a visit space other than the predetermined facility, and a control unit configured to perform, when the user is present in the visit space, interchange processing of providing the output power to the visit space based on the data of the output power.
