A Survey on Efficient Consensus Mechanism for Electricity Information Acquisition System

The current electricity information acquisition system has been able to meet some basic needs of Power system data sharing, but with the development of Power system, data sharing is faced with some problems of scale expansion, and the data acquisition method is complex, which puts forward new challenges to the timeliness and security of data. As one of the core technologies of blockchain technology, consensus mechanism has been used in various fields widely. It is a very suitable way to use consensus algorithm for data sharing in electricity information acquisition system and make use of the high efficiency and expansibility of some consensus algorithms to realize the efficient collection of electricity information acquisition system and the real-time query of data by users while saving energy. In this article, analyzing the actuality of electricity information acquisition system, We select 3 consensus algorithms suitable for power field to meet its efficient data synchronization, including Raft, RSP and PoS. After analysis and comparison, the results show that the improved algorithm for three kinds of algorithms can solve some efficient electricity information acquisition system, storage, energy saving and safety problems.
