For the problem of high penetration of new energy in rural areas, the method of operation optimization of rural microgrid group and distribution network based on cooperative game theory is proposed. In order to optimize the output level, battery charge and discharge, and interruptible load of each power supply in different periods of time in the microgrid, the minimum objective function of operation cost of microgrid including wind power, photovoltaic, biogas power generation, energy storage and interruptible load is established.
