Supporting Smart Meter Context Management Using OWL Ontology and Hyperledger Fabric Blockchain

The usage of electrical and electronic appliances is on the rise in both homes and businesses. The smart energy device has various potential applications, including power measurement, power control, and data exchange between smart power plants and individual customer endpoints. However, the current smart energy meters primarily provide data on the overall electricity consumption of a home or business, without considering context or information security. To effectively manage energy, it is essential to have a knowledge interpreter and a secure information storage system, as most households and industries lack awareness of energy consumption, data privacy, and actions that can reduce demand. Hence, this study proposes a context-aware smart energy metering system and a secure information storage management system based on blockchain. Moreover, we analyzed the Sustainable Data for Energy Disaggregation (SustDataED2) dataset. Similarly, the Hyper Ledger Fabric (HLF) blockchain system functions as a storage ledger, ensuring the integrity of information and protecting it against malicious attacks.
