Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the energy storage system provides functional services without reasonable power scheduling, then the system can operate, but the output power and remaining stored energy cannot support the functional services, leading to system failure
Solution Approach 1:
The controller obtains information about user equipment in advance and determines actual user scheduling powers before the energy storage system provides functional services. This preliminary power scheduling ensures that the output power and remaining stored energy can support the intended functional services, preventing system failure while maintaining reliability.
2Adaptability or versatility
If the energy storage system operates without obtaining user equipment information, then the system structure remains simple, but the system cannot provide reasonable power scheduling, leading to inability to support functional services
Solution Approach 1:
The controller is designed to perform multiple functions: obtaining user equipment information, determining actual user scheduling powers, and controlling the converter and battery packs. This multi-functional controller enables the energy storage system to adapt to different user equipment and provide reasonable power scheduling without requiring separate dedicated devices for each function.
3Productivity
If the controller controls the converter and battery packs without obtaining user equipment information, then the control process is simple, but the power allocation is unreasonable, leading to system failure
Solution Approach 1:
The controller obtains user equipment information and determines actual user scheduling powers before controlling the converter and battery packs. This preliminary action ensures reasonable power allocation and maximizes energy storage utilization, while the time required for information acquisition is minimized through efficient communication protocols and processing.
