Blockkedjesystem för smarta elnät : En undersökning om befintliga blockkedjesystem där deras egenskaper analyseras, och kvantitativa mätningar gällande deras responstid utförs
Sammanfattning: The interest in blockchain technology is increasing and is being applied in more areas than just cryptocurrencies. To facilitate the use of blockchains suppliers are launching blockchain-as-a-service, which is a fusion between cloud service and blockchain. The objective of this project is to investigate which existing blockchain system is most suitable for an energy trading scenario, where the idea is that in the future it will be possible to buy and sell local energy via smart grids. The project starts with literature studies to gain basic and in-depth knowledge about blockchain systems, cryptocurrencies and smart grids. Furthermore, the availability, documentation and payment options of a number of systems are investigated. Then, based on how they meet the above parameters, two systems move on to the test phase. To perform the quantitative measurements, a blockchain member is deployed at the respective supplier with the associated software. To measure the response time, a code is written that can send one or more, small or large transactions. This leads to a result that shows that both systems are able to fit into an energy trading scenario, but that Kaleido has faster response time than Azure Blockchain Service. The conditions have been largely the same for both blockchain systems, but there are a number of factors that can affect the measurement results. The report is rounded off with an ethical and societal discussion where the blockchain's impact on the black market is addressed, how it can benefit when it comes to COVID-19, if it really is a sustainable alternative given its energy consumption, and finally proposals for further work.
