Abstract
A novel architecture for smart meters in a Virtual Power Plant (VPP) is introduced in this research. By integrating blockchain technology, the system not only measures and quantifies diverse consumer data but also facilitates immediate control, hence improving demand responsiveness in a VPP environment. Mathematical models were created to optimize profit, battery reserve, and power balance. A novel transaction and security algorithm that enables peer-to-peer (P2P) transactions in a secure setting is used in conjunction with a power flow algorithm for real time monitoring and control to implement the proposed model. The lightweight characteristics of the algorithms enable faster and more effective computer processing. The unique identifier issued to each smart meter facilitates seamless integration with a blockchain smart contract, therefore enabling improved and secure P2P transactions. An innovative experimental setup demonstrated the framework’s ability to effectively manage energy flows while maintaining seamless wireless connection with the grid and executing transactions. The smart meter demonstrated exceptional efficiency in load management, resulting in an average loss of 1.9524W. A dedicated dapp was created just for this purpose. Through the strategic integration of algorithms and blockchain technology, this framework enhances the efficiency and reliability of the metering infrastructure, while also enabling secure transactions.
