Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing power management systems lack robust security measures to prevent external intrusions during two-way communication between advanced metering infrastructure (AMI) and energy management systems (EMS), which can lead to network failures in smart grid operations.
Innovation Solution
A power management network system that includes an advanced metering infrastructure (AMI) for real-time power measurement and communication, an energy management system (EMS) connected to AMI for electricity supply, and a security reinforcement unit to periodically update security codes, ensuring secure communication through bidirectional confirmation and encoding processes.

Engineering Contradiction Analysis
1Productivity
If two-way communication is implemented between power supply source and network, then energy efficiency is improved through real-time information exchange, but network security deteriorates due to potential external intrusions
Solution Approach 1:
A security reinforcement unit is introduced as an intermediary component between the AMI and EMS systems. This unit acts as a mediator that verifies security codes before allowing communication, thus protecting the network from external intrusions while maintaining the benefits of two-way communication for energy efficiency
Solution Approach 2:
Security codes are pre-established and stored in both the AMI and EMS systems before communication occurs. The security reinforcement unit performs preliminary verification of these codes before allowing any data exchange, preventing unauthorized access while enabling legitimate real-time information exchange for energy management
2Reliability
If security codes are periodically updated, then network security is enhanced, but device complexity increases due to additional security reinforcement unit
Solution Approach 1:
The security reinforcement unit is designed to automatically perform security code verification and periodic updates without requiring manual intervention. The system self-manages the security updates by exchanging verification codes between AMI and EMS, reducing operational complexity while maintaining enhanced security
Solution Approach 2:
Security codes are updated periodically through automated exchanges between the AMI and EMS systems. The security reinforcement unit manages these periodic updates systematically, providing continuous security enhancement without requiring constant manual configuration or complex real-time management
