摘要
针对微电网接入电网后,满足电网稳定性的工作要求,在微电源的输出功率传输特性和下垂控制原理的基础上进行分析,采用下垂控制方法进行改进,改进后的下垂控制设计包括3个相互作用的下垂控制回路调节,利用Matlab/Simulink软件搭建微电网仿真模型.研究结果表明:微电网在不同运行状态下,微电网均实现稳定运行状态,从而验证改进的下垂控制方法有效可行.
In order to meet the work requirements of grid stability after the micro-grid connected into the grid, this paper analyzed the studies of micro-grid stability on the basis of the output power of the power supply and transmission characteristics of the micro-droop control principle, and adopted the droop control method for improved droop control design which consists of three interacting droop control loop adjustment. MATLAB/Simulink software was used to build a micro-grid simulation model running on different micro-grid experiment. The results show that the micro-grid can achieve the stable operation status under different operation status which verified the effectiveness and feasibility of the improved droop control method.
