Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If distributed battery systems are deployed at consumer premises, then local electricity management and demand management services are improved, but costs and life-cycle limits worsen
Solution Approach 1:
The patent combines multiple functions into a single distributed battery system unit: power storage, DC power supply, demand monitoring hub, and communication capabilities. This integration reduces overall system costs and simplifies deployment at consumer premises while maintaining comprehensive local electricity management functionality.
Solution Approach 2:
The distributed battery system is designed to perform multiple functions simultaneously: it provides local DC power supply, monitors demand, communicates with the grid, and participates in aggregate grid storage services. This multi-functionality maximizes the utility of each deployed unit, improving ease of operation while optimizing cost-effectiveness through versatile resource utilization.
2Ease of operation
If distributed battery systems are deployed at consumer premises, then demand management services are improved, but lack of smart management solutions worsens deployment effectiveness
Solution Approach 1:
The system incorporates communication means that enable bidirectional data exchange between the distributed battery units and the central management system. This feedback mechanism allows the central system to receive operational data from individual units and provide control signals, enabling effective smart management without requiring complex local intelligence at each deployment point.
Solution Approach 2:
The patent introduces a central management system that acts as an intermediary between individual distributed battery units and the grid. This intermediary coordinates charging schedules, aggregates demand data, and manages collective resource deployment, simplifying the management architecture while improving overall demand management effectiveness.
3Reliability
If battery assemblies are managed as collective resource, then grid storage services are improved, but lack of aggregation management worsens resource utilization
Solution Approach 1:
The patent merges multiple distributed battery assemblies into a coordinated collective resource through communication networks. Individual units retain their local functionality while being aggregated into a unified system that provides enhanced grid storage services, achieving improved reliability without requiring physically centralized management infrastructure.
