摘　　要：灌溉、电动机、照明和其他电力用途都越来越依赖太阳能,将太阳能系统集成到农村微电网中变得越来越重要。基于此,提出了基于光伏的微电网的非线性DC/DC转换器的建模和管理,这种方法的主要优点是转换器模型可以线性化,从而扩大了可能的工作点范围。单端初级电感变换器和升压变换器都用于将光伏模块的电力转换为更高的电压形式,并通过MATLAB的仿真结果证明了所建议的控制的效率。Irrigation,electric motors,lighting,and other power uses are increasingly dependent on solar energy,and integrating solar systems into rural microgrids is becoming increasingly important.Based on this,the modeling and management of nonlinear DC/DC converters for photovoltaic-based microgrids was proposed.The main advantage of this approach is that the converter model can be linearized,thereby expanding the range of possible operating points.Both the single-ended primary inductor converter and the boost converter were used to convert the power of the photovoltaic module into a higher voltage form.The simulation results through MATLAB prove the efficiency of the proposed control.
