Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional power generators are connected to ensure 100% power capacity, then reliability of power supply is improved, but device complexity and operational cost increase
Solution Approach 1:
The master controller continuously monitors the operational status of renewable power generators and controllable load devices, using feedback signals to dynamically adjust power distribution. This enables the system to maintain reliability by automatically activating conventional generators only when renewable generation is insufficient, rather than requiring all generators to be permanently connected.
Solution Approach 2:
The system transitions from a static configuration where all generators must be connected to ensure reliability, to a dynamic configuration where the master controller adjusts generator activation and load distribution in real-time based on renewable generation availability and load requirements.
2Power
If conventional power generators are connected to ensure 100% power capacity, then power supply capacity is improved, but loss of energy increases
Solution Approach 1:
Instead of requiring all conventional generators to be connected at full capacity to ensure power availability, the system applies partial action by activating only the necessary portion of conventional generation capacity when renewable sources are insufficient, thereby reducing energy waste from operating unnecessary generators.
Solution Approach 2:
The master controller ensures continuous useful action by continuously monitoring renewable generation and load demands, dynamically adjusting the operation of conventional generators to maintain adequate power capacity only when and where needed, eliminating periods when conventional generators would operate uselessly.
3Adaptability or versatility
If conventional power generators are connected to ensure 100% power capacity, then adaptability is improved, but productivity decreases
Solution Approach 1:
The master controller uses real-time feedback from renewable power generators and controllable load devices to dynamically adjust system operation, enabling adaptability to changing conditions while maintaining high productivity by avoiding the inefficiency of running all generators at full capacity regardless of actual needs.
Solution Approach 2:
The system achieves adaptability through dynamic control where the master controller continuously adjusts generator activation and load distribution based on real-time conditions, rather than relying on a static over-provisioned configuration that sacrifices productivity.
4Loss of energy
If master controller coordinates power generation and consumption, then loss of energy is reduced, but device complexity increases
Solution Approach 1:
The master controller performs multiple functions including monitoring renewable generation, managing controllable load devices, coordinating conventional generators, and optimizing power distribution. This multi-functionality consolidates control tasks into a single device, reducing the need for multiple separate control systems and mitigating the complexity increase.
Solution Approach 2:
The system merges generation control and consumption management into a unified control architecture where the master controller coordinates both renewable and conventional generators along with controllable loads, enabling optimized energy loss reduction through centralized coordination rather than distributed independent controls.
