Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If distributed power supply resources are utilized, then power system reliability is improved, but control complexity increases due to large number, diversity, small scale, and dispersion of resources
Solution Approach 1:
The patent segments the control function into multiple distributed control nodes rather than using a single centralized controller. Each control node manages a subset of power supply resources, breaking down the complex control task into smaller, manageable segments that can be handled independently, thus reducing overall control complexity while maintaining system reliability.
Solution Approach 2:
The patent introduces intermediary control nodes that act as mediators between individual power supply resources and the overall power system. These intermediaries aggregate information from multiple small-scale resources, perform local coordination, and simplify the control interface, thereby managing the complexity arising from the large number and diversity of distributed resources.
2Productivity
If direct control of multiple distributed resources is implemented, then power distribution efficiency is improved, but operational difficulty increases due to dispersion and diversity of resources
Solution Approach 1:
The patent merges multiple distributed control functions into a coordinated multi-node control system. By combining the capabilities of individual control nodes while maintaining their distributed nature, the system achieves efficient power distribution across dispersed resources without requiring complex direct control of each resource individually.
Solution Approach 2:
The patent creates universal control nodes that can handle multiple types of power supply resources (solar, wind, storage, etc.) with diverse characteristics. These multi-functional control nodes adapt to different resource types and locations, simplifying operation despite the diversity and dispersion of underlying resources.

AI summary
An apparatus and method for collecting power from distributed power supply resources are provided. The method includes transmitting a signal for inquiring whether supply of demand-side power supply resources is possible to a providing side that provides demand-side power supply resources, selecting demand-side power supply resources to be utilized, based on power supply resource-related information for each of available demand-side power supply resources, which is received from the providing side, and notifying the selection results to the selected demand-side power supply resources.
