Abstract
In this paper, a novel microgrid (MG) restoration framework is proposed based on Blockchain Technology (BCT). The proposed method consists of a two-stage restoration process. In the first stage, stable Blockchain (BC) links are formulated with the grid-forming Distributed Energy Resources (DERs). In the second stage, load assignment is carried out based on the priority level of the load. The miners run through the consensus mechanism to accommodate the priority-based loads to their corresponding BC links. The consensus mechanism provides the value of an index, known as Combined Stability Measurement (CSM). The BC link, with the higher CSM value, is declared as the winner of the consensus mechanism. Subsequently, the targeted priority load is assigned to that winner BC link. The proposed BCT-based restoration framework is tested with the modified IEEE-33 and IEEE-69 bus test systems using the Ethereum blockchain platform.
