After the switch with classical U/f control mode on the basis of the control strategy when switching instantaneously, adding the energy storage device and load control strategy by means of MATLAB/Simulink simula- tion software, setting up the model of various components of the simulation of micro-grid isolated operation mode, also by the dropping of power supply voltage to analog changes of voltage of iso- lated network. Through the control method of the stability of the various micro network switching, we then find the best way by reasonable collocation. The actual system has a certain significance.
