Abstract

The United Kingdom has pledged to reach Net Zero by 2050, which means removing as much greenhouse gas from the atmosphere as it emits. One of the main challenges associated with this ambitious target is the decarbonisation of the power grid by 2030. Achieving this goal requires a significant transformation of the energy sector, particularly in how energy supply and demand are balanced. Flexibility markets, which facilitate the dynamic adjustment of electricity supply and demand in real-time, play a crucial role in enabling the integration of renewable energy sources and ensuring grid stability. However, the current models for managing these markets face limitations in transparency, efficiency, and cyber security. This thesis explores blockchain-based models as a novel solution to support the digitalisation of flexibility markets, addressing the before mentioned challenges. Blockchain technology offers a decentralised, secure, and transparent framework that can improve the operation of flexibility markets by enabling more efficient and trustworthy data transactions. Through leveraging smart contracts and distributed ledger technology, blockchain can support the real-time exchange of energy and services between market participants, while also providing a robust platform for verifying and recording transactions. This thesis aims to develop and evaluate blockchain-based models that can improve the efficiency, security, and scalability of flexibility markets. This goal has been addressed through the design and evaluation of three integrated blockchain-based solutions: a) A distributed ledger technology-based framework and architecture was used to demonstrate the accessibility, transparency and redundancy of deploying the digital environment for facilitation of flexibility services and market in electricity distribution networks. b) A blockchain-based flexibility settlement mechanism using novel zero knowledge proofs was developed to demonstrate a superior cyber-security method for settling flexibility transactions without disclosing electricity profile information. c) A blockchain-based financing model using rotating savings and credit associations was developed to demonstrate a sustainable mechanism to finance the purchasing of flexibility assets
