【Abstract】Decomposing the large distribution grids into interconnected microgrids (MGs) can potentially enhance the power system's efficiency, sustainability, resiliency, and reliability. However, energy management within the entire network would be more complicated and challenging. This article develops a novel energy management framework for interconnected MGs based on a blockchain technology. Utilizing the blockchain technology can potentially enhance the system security, and also reduce the system risks, mitigate financial fraud, and cut down the operational cost. A priority list is first defined to get into an efficient energy tradeoff within the interconnected MGs. Moreover, the incentive contract is proposed to provide a price discount for a party that purchases more power from one sub-MG. A stochastic framework based on the unscented transform technique is also established to manage the uncertainties associated with hourly load demands and output power of renewable energy sources. The proposed model is formulated as a mixed-integer linear programming problem and solved through the blockchain-based energy/power management algorithm. The case study includes residential, industrial, and commercial MGs-namely, three residential, one commercial, and one critical load (hospital). The simulation results show the high efficiency and effectiveness of the proposed model and validate its economic and reliability merits.
