  The application of renewable energy sources in the power grid, especially in
smart grids, where there is a bidirectional transfer of data and power,
increases the necessity of tracking the system's state. Additionally, the
complexity of coupling between communication and the electrical infrastructure
in a smart grid will allow a vast amount of vulnerabilities. Increasing the
state estimation accuracy will help the smart grid operator efficiently manage
the system. In this paper, we propose a combination of distributed state
estimation and a blockchain designed communication platform. Additionally, the
asynchronous manner for data transmission, which is more likely to happen in
the real world, has been considered the second case in this work. Finally, a
detailed analysis regarding the application of blockchain in distributed state
estimation has been provided. The numerical analysis shows that the proposed
method meets real-world performance requirements and brings high security and
reliability to the distributed state estimation process.
