A State-aware Proof of Stake Consensus Protocol for Power System Resilience

Abstract

The resilience of the power grid is critical for the energy delivery system and the assurance of the energy distribution process. The integration of blockchain technology with the power grid can provide a consistent view of the system state and constant validation. However, there are still significant challenges in the integration of blockchain in current power system architecture. From the cyber physical perspective, the physical components in the power system are heterogeneous and there are limited communication capabilities among these components. In this work, we propose a two-layer architecture that enables a state-aware blockchain integration with power grid state estimation and still scales in terms of performance dealing with high volume data.
