Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If energy storage solutions are implemented using base station batteries, then the stability of energy supply is improved, but the device complexity increases due to coordination across multiple communications service providers
Solution Approach 1:
The patent introduces a coordination entity that acts as an intermediary between multiple communications service providers and the energy storage system. This intermediary manages the selection of base stations for charging/discharging operations based on agreements with multiple CSPs, centralizing the complex coordination tasks and simplifying the overall system architecture while maintaining reliable energy supply across the network
Solution Approach 2:
The system enables base station batteries to serve multiple functions: they act as both backup power sources for individual base stations and as distributed energy storage units for grid stabilization. By coordinating multiple base stations from different CSPs, the system creates a universal energy management platform that handles both communication network reliability and power grid stability simultaneously
2Reliability
If base station batteries are used for energy storage, then the intermittency of renewable energy is mitigated, but the loss of energy increases during charging and discharging cycles
Solution Approach 1:
The system performs preliminary charging of base station batteries during periods of low energy demand and high renewable energy availability. By proactively storing energy in advance of peak demand periods, the system reduces the need for frequent charging-discharging cycles, thereby minimizing energy losses while ensuring constant energy supply when needed
Solution Approach 2:
The coordination entity dynamically adjusts operational parameters such as charging/discharging rates, state of charge thresholds, and cycle frequencies based on grid conditions, renewable energy availability, and demand patterns. By optimizing these parameters, the system minimizes energy losses during battery operations while maintaining reliable energy supply
