Blockchain- Enhanced Secure Data Exchange for Interoperable Smart Grid Systems

With the proliferation of interconnected electrical systems and the rise of decentralized energy resources, the need for secure, transparent, and decentralized data exchange within smart grid systems has become imperative. This paper investigates the potential of integrating blockchain technology into smart grid systems to ensure secure data exchange while enhancing interoperability. The study establishes that blockchain's immutable ledger capabilities can be tailored to authenticate and validate the vast volume of transactions inherent in smart grid systems. Additionally, a prototype for blockchain-enhanced secure data exchange is presented, emphasizing consensus algorithms that are both energy-efficient and capable of real-time processing. The prototype demonstrates a substantial reduction in malicious data injections, unauthorized access, and other potential security breaches. Furthermore, the blockchain's decentralized nature promotes increased resilience against single-point failures, promoting reliability in smart grid data exchange. In essence, the synergy between blockchain technology and smart grid systems offers a promising avenue for creating a more secure, transparent, and interoperable energy network, pivotal for the future of distributed energy systems.
