说明：  以单相光伏发电并网系统为研究对象，基于Matlab/Simulink平台，进行了光伏电池的建模，MPPT模型的搭建，并实现了系统的并网。
(Taking the single-phase photovoltaic power grid system as the research object, based on MATLAB / Simulink platform, the photovoltaic cell modeling and MPPT model are built, and the grid connection of the system is realized.)
