摘要:
本文针对微网在并网转孤网的情况下出现的不稳定问题，在切换后采用U/f控制等经典方式的控制策略基础上，切换瞬间加入了储能装置和负荷控制策略相结合的控制方法，借助Matlab/Simulink仿真软件，建立了各种元件的模型，仿真了微电网孤网运行方式，同时通过电源电压跌落工况模拟切换到孤网电压变化。通过对各种微网切换稳定性的控制方法，进行合理的搭配找到最佳方案，对实际系统具有一定的指导意义。
For micro-grid in grid connected turn isolated network, there is unstable problem. 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.
