基于干扰观测器的多光伏光柴混合系统协调控制研究

Study of the Coordinated Control for the Multiple PV-diesel Hybrid System Based on the Disturbance Observer

提出了一种基于干扰观测器的多光伏光柴混合系统协调控制方法,并与采用最大功率跟踪控制而不加协调的多光伏系统的供电效果进行了对比.仿真结果证明,该方法减小了光柴混合系统的频率偏差,并且使各个光伏系统获得了较大功率输出.

A mulitiple PV-diesel hybrid system based on the disturbance observer is proposed to coordinate the photovoltaic panels to contribute to the stability of the system to provide high quality of electricity. The proposed method is compared with the conventional method for every PV system with only M PPT control. The simulation result proves that the proposed method can reduce the frequency deviation and the output power of every PV can reach a bigger volume.
