Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a large-scale energy storage apparatus is configured for the power grid system, then electric energy compensation during peak supply and energy storage during low supply can be achieved, but investment cost increases significantly
Solution Approach 1:
The patent segments the energy storage function across multiple base stations rather than concentrating it in a single large-scale apparatus. Each base station's energy storage battery independently participates in grid energy regulation, distributing the investment burden and achieving collective energy compensation效果
Solution Approach 2:
The energy storage batteries in base stations serve dual functions: providing backup power for base station operations and participating in power grid energy regulation. This multi-functionality eliminates the need for dedicated large-scale energy storage infrastructure, reducing investment costs while maintaining grid reliability
2Loss of energy
If traditional pumped storage or mechanical energy storage methods are used, then electric energy can be transferred and stored in the power grid system, but conversion efficiency is relatively low
Solution Approach 1:
The patent replaces traditional mechanical energy storage methods (pumped storage, flywheel) with electrochemical energy storage batteries. This substitution eliminates mechanical-to-electrical conversion losses, achieving higher round-trip efficiency since batteries can charge and discharge electricity directly without mechanical intermediaries
Solution Approach 2:
The patent changes the energy storage parameter from mechanical forms to electrochemical forms. By using batteries with high charge-discharge efficiency, the system achieves superior energy transfer efficiency compared to mechanical systems that suffer from friction, conversion losses, and maintenance-related inefficiencies
