| dc.description | The increasing penetration of inverter-based generation has made modern power grids highly dependent on synchrophasor based WAMS and two-way communication infrastructures. As a result, the deployment of Phasor Measurement Units (PMUs) at substation buses has grown significantly. This rapid deployment has also increased the volume of data transmission, thereby expanding the surface of unauthorized access. Blockchain (BC) technology has recently been proposed as a promising solution to preserved PMUs data integrity and confidentiality. In conventional IoT-based BC architectures, each sensor reading is often processed as an individual transaction resulting network congestion and processing overhead that negatively affect real-time data processing. To overcome the limitation, this thesis proposed a subdivision-based BC-integrated WAMS framework utilizing a distributed consensus algorithm and fast signature scheme. The primary objective of the thesis is to investigate data communication, automatic monitoring of electrical parameters and security aspects in the substation domain. This is achieved through the using of MATLAB-SCADA and Hyperledger Fabric based co-simulation test bed. Subsequently, the thesis demonstrates the implementation of proposed framework for secure phasor data sharing. Additionally, the thesis delves into discussing the performance metrics and transaction handling ability of the proposed scheme in comparison with existing state-of-the-art. Experimental results from quantitative analysis highlight the impact of significant reduction in transaction volume by 99.4–99.8 %. Therefore, queuing delay becomes negligible, and latency drops by 3-5s approximately that decrease network congestion issues and improve overall scalability. | |
