Innovation Solution
A TVWS-based system that collects storage voltage and power consumption data from hybrid energy storage apparatuses, including supercapacitors and batteries, to generate and enforce charging/discharging policies, control power supply to loads, and manage switching policies through a central control server and gateway, ensuring stable and efficient energy distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If hybrid energy storage systems operate without effective control service, then system simplicity is maintained, but energy distribution efficiency deteriorates
Solution Approach 1:
The control server dynamically adjusts charging/discharging parameters (power levels, voltage thresholds, current rates) based on real-time storage voltage data and power consumption data to optimize energy distribution efficiency without requiring complex hardware modifications
Solution Approach 2:
The system implements a feedback control mechanism where the control server continuously receives storage voltage data and power consumption data from the hybrid energy storage apparatus, processes this information, and generates optimized charging/discharging control commands that are transmitted back to the apparatus for real-time parameter adjustment
2Reliability
If real-time data collection and control is implemented, then energy management stability is improved, but system complexity increases
Solution Approach 1:
The control server acts as an intermediary between the hybrid energy storage apparatus and the energy management system, centralizing data processing and control decision-making to improve stability while avoiding distributed complexity across multiple control nodes
Solution Approach 2:
The control server performs multiple functions including data collection, data processing, charging/discharging policy generation, and command transmission, consolidating these functions into a single multi-functional unit that improves reliability without proportionally increasing overall system complexity
3Productivity
If charging/discharging policies are generated based on received data, then power supply optimization is improved, but data processing complexity increases
Solution Approach 1:
The control server optimizes power supply by dynamically changing operational parameters (charging power, discharging power, voltage thresholds) based on processed storage voltage data and power consumption data, achieving power supply optimization through parameter adjustment rather than complex system reconfiguration
Solution Approach 2:
The control server generates charging/discharging policies in advance based on analyzed data patterns and system state, preparing optimized control commands before they are needed, which simplifies real-time decision-making while maintaining high power supply optimization
