Resilient and decentralized demand-side management in smart grids using blockchain.

Area of Science:

• Computer Science
• Electrical Engineering
• Cybersecurity

Background:

• Smart grids and Internet of Things (IoT) enable advanced energy services like smart metering and EV charging.
• Data transmission in these systems creates vulnerabilities, including data manipulation and service interruptions.
• Existing centralized demand-side management systems suffer from a single point of failure.

Purpose of the Study:

• To propose a decentralized, blockchain-based demand-side management scheme.
• To enhance security and robustness against cyber threats in smart grid communications.
• To ensure mutual authentication between IoT devices and utility centers.

Main Methods:

• Implementation of a blockchain-based demand-side management scheme.
• Integration of mutual authentication protocols between IoT devices and utility centers.
• Security evaluation using the Automated Validation of Internet Security Protocols and Applications (AVISPA) tool.

Main Results:

• The proposed scheme provides enhanced security and transparency for energy data.
• Security analysis using AVISPA confirms the robustness of the system.
• Performance analysis shows reduced computation time and communication costs compared to existing methods.

Conclusions:

• The blockchain-based approach offers a secure and efficient solution for demand-side management.
• Decentralized authentication is crucial for mitigating vulnerabilities in IoT-enabled smart grids.
• The proposed scheme outperforms current state-of-the-art approaches in security and performance.
