Solution Overview
Problem
Variations in communication path characteristics within a network lead to inaccuracies in power supply and demand regulation in electric power systems using storage batteries, as operation instructions are received differently by each battery, affecting the precision of regulation.
Innovation Solution
A battery control system that detects communication path characteristics, selects batteries with communication paths within a predetermined range for regulation, and supplies operation instructions to these selected batteries to maintain consistent regulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If operation instructions are transmitted to multiple storage batteries through different communication paths, then the system can regulate power supply and demand using distributed energy storage, but variations in communication path characteristics cause deterioration in regulation accuracy
Solution Approach 1:
The patent segments the communication network into multiple communication paths and identifies specific paths with favorable characteristics for each storage battery. By dividing the communication network into distinct paths and selecting batteries based on their communication path characteristics, the system can regulate power supply and demand while maintaining accuracy by choosing batteries whose communication paths fall within predetermined characteristic ranges.
2Adaptability or versatility
If all storage batteries are used for regulation, then the system maximizes energy storage utilization, but communication path variations cause inconsistent reception of operation instructions
Solution Approach 1:
The patent applies local quality by establishing predetermined communication path characteristic ranges and selecting storage batteries based on whether their communication paths fall within these ranges. This allows the system to maintain high adaptability by utilizing multiple batteries while ensuring stability in instruction reception by selecting only those batteries with communication paths that meet specific characteristic criteria.
