A Novel Blockchain Based Approach to Exchanging Information and Data in Power Systems

Exchanging information and data using cloud computing in power systems is now becoming common practice. However, there are still many challenges such as data security, interoperability, and scalability that need to be considered. In this paper, the authors have exploited blockchain technology by integrating it with Hadoop to enhance interoperability concerning power system operators at both transmission and distribution levels. A blockchain based approach is developed to exchange information and data within power systems. This approach enables users to exchange information and data without losing ownership or control of the data. The proposed approach provides the solutions to three important issues: scalability, data ownership, and interoperability. The case studies as presented in this paper evaluate the effectiveness of the proposed novel approach for enhancing information and data exchange. The paper specifically evaluates enhanced performance with regard to scalability, latency, and computational time.
