Abstract:

Traditional automatic generation control(AGC) parameter management relies on centralized databases, which pose risks of data tampering, low efficiency of multi-party collaboration, insufficient operational transparency, and difficulties in historical tracing. Blockchain technology is introduced into the entire process of AGC parameter management to address challenges including parameter data verification, certification, and traceability. Firstly, a blockchain architecture for AGC parameter control in the power grid is designed. Secondly, the key technologies for constructing the AGC parameter control chain are studied. Finally, through experimental verification and analysis, the consistency verification, certification efficiency, consensus efficiency, and other performance of the parameter control chain are analyzed. The results show that the parameter control chain designed has functions such as efficient certification, trustworthy traceability, and consistency verification of key parameter data on the chain, which can significantly improve management efficiency and security.
