Blockchain and Cybersecurity Applications in Smart Grids for Renewable Energy Transactions

The integration of blockchain technology into smart grids presents a transformative solution to address the growing concerns surrounding energy data security, transaction transparency, and decentralized energy management. This chapter explores the pivotal role of blockchain in enhancing the functionality and resilience of smart grids, particularly in the context of renewable energy transactions. By leveraging blockchain’s decentralized nature, immutable ledger, and cryptographic security, smart grids can secure data transmission, ensure transparent peer-to-peer (P2P) energy trading, and foster trust among consumers and energy producers. The chapter delves into various case studies that highlight the successful implementation of blockchain as a security layer, demonstrating its potential to mitigate cyber threats, prevent data manipulation, and improve overall grid efficiency. The intersection of blockchain with emerging technologies such as artificial intelligence (AI) and the Internet of Things (IoT) is examined, providing a comprehensive outlook on future developments in smart grid ecosystems. Key challenges, opportunities, and the scalability of blockchain solutions for large-scale energy systems are critically assessed. This chapter serves as a timely resource for researchers, policymakers, and industry stakeholders, offering valuable insights into the adoption and impact of blockchain in the renewable energy sector.
