摘要:
在典型低压微电网中,多个分布式电源逆变装置通过公共连接点与大电网相连。为了模 拟无互联线并联结构的模拟同步发电机特性,在并网逆变器控制系统中,广泛采用下垂控制实现分 布式电源功率分配。针对传统下垂控制功率分配存在误差问题,提出一种新型自适应下垂控制方 案来增加功率分配精度;为了提高低压微电网中布式电源逆变器的抗干扰和动态性能,引入频率、 电压补偿环节在自适应下垂控制中来提高系统鲁棒性。将上述控制策略通过Matlab/Simulink 仿真 来验证本文所提方案可以提高微网暂态性能。
Abstract:
In a typical low?voltage micro?grid,multiple distributed generation inverters are connected to the large grid through common connection points. In order to simulate the characteristics of the analog synchronousgeneratorwithoutinterconnectedparallelstructure,thedroopcontroliswidelyusedinthecontrol system of grid?connected inverters so to realize the power distribution of distributed generators. In view of the error of power allocation in traditional droop control,a kind of new adaptive droop control scheme is proposed to improve the accuracy of power allocation. For improving the anti?interference and dynamic performance of distributed power supply inverters in low?voltage micro?grid,frequency and voltage compensation links are introduced to improve the robustness of the system in adaptive droop control.The above control strategy is verified by simulation with Matlab/Simulink to improve the transient performance of micro?grid.
