Research on Micro-Grid Electric Energy Transaction Mechanism Based on Master-Slave Smart Contract

In view of the increasing generation of the distributed generation system, the increasing randomness and intermittence of micro-grid have been attracted much attention. The complexity and decentralization of power status information, which is difficult to meet the needs of the current power market in the stability and efficiency of the grid transaction. According to the randomness and intermittent characteristics of distributed generation, this paper innovatively proposes a micro-grid electric energy transaction mechanism based on Master-Slave smart contract and designs a framework of the Cyber-Physical System (CPS) for micro-grid. The specific constraints of micro-grid topology are analyzed. And in the cloud platform, smart contracts are used to reasonably manage the transaction order when the stochasticity of distributed generation generates excess or insufficient electricity.
