摘　　要：根据动力学网络的新视角,提出采用一、二阶混合非均匀Kuramoto模型建立微网模型。通过搭建微网系统的传统仿真模型和微网系统的Kuramoto模型,创新地以相位振子双态模型描述微网公共连接点(point of common coupling,PCC)处并/离网状态的独特方法表征微网并网和孤岛两种运行模式,以验证此建模方式的准确性。微网动态实质是多能源形式能量的转化、传输、消耗的过程,以能量观点研究其功率流动及控制问题,则更符合微网系统运行的本质规律。According to the new perspective of dynamic network,and the first-order and second-order mixed nonuniform Kuramoto model is proposed to establish the microgrid model.By building the traditional simulation model of microgrid system and Kuramoto model of microgrid system,this paper creatively uses the phase oscillator twostate model to describe the merging and off grid state at the point of common coupling(PCC)of microgrid,and represents the two operation modes of microgrid grid connection and island,so as to verify the accuracy of this modeling method.The dynamic essence of microgrid is the process of energy transformation,transmission and consumption in the form of multi energy.Studying its power flow and control from the perspective of energy is more in line with the essential law of microgrid system operation.
