摘要
Abstract
When low-voltage micro-grid is under island mode , the traditional droop control can not effectively control the voltage , frequency and stability of system when the load changes .An improved self-regulating droop control strate-gy based on the conventional droop control is proposed in order to solve the above problems .The PI feedforward con-trol is introduced , and the voltage and frequency are adjusted by changing the slope of the droop curve and translation of the curve.First of all, the principles and methods of the control strategy are analyzed , then the traditional droop control strategy and improved control strategy are simulated and analyzed through Simulink platform .The simulation results show that the proposed improved droop control strategy can control the voltage and frequency more effectively and rapidly , so that the low-voltage micro-grid running more stably in island mode .关键词
