摘要
针对容量有限、光储单元容量较低的中小功率船舶光柴储交流微电网系统的稳定性问题,提出基于光储逆变器的船舶光柴储交流微电网多级控制策略。建立由柴油发电机组模型、光储系统模型以及与网侧功率模型构成的船舶光柴储微电网系统的小信号模型,分析系统内控制参数对状态矩阵特征值的影响,获得船舶光柴储微电网系统的暂态稳定性,确定稳定域内控制器参数的选择范围。最终获得船舶电网电压和频率的仿真结果,为船舶光柴储微电网系统的稳定运行和控制参数的设计提供重要的理论基础。
For the islanded marine diesel-PV-battery(DPB) hybrid ac microgrid(MG) system with capacity limitation and low power of PV-battery system(PBS), a multi-level control strategy based on inverter in PBS of marine DPB MG system is proposed in the paper. The small-signal model of the hybrid system is composed of three subsections of diesel-generator system(DGS), PBS and power grid including load. Analyzing the influence of the inner controller parameters on the eigenvalues, the system transient stability features is analyzed and the controller parameters range for stability are obtained. Finally, the grid voltage and frequency transient waveforms in time-domain are given. The results of the paper provide key theory for marine DPB MG system stability and controller parameters design.
