Modeling and simulation of a Micro-grid connected with PV solar cell & its protection strategy

In the present day scenario due to change the rapid demand and over global climate change in increased the sustainable Distributed generation (DG) resources such as fuel, wind and solar. Society moving to the conventional resources like as solar, wind etc. To fill surplus demand need alternative sources like solar cell. It has a distinct concern in this scenario as it is pollution free, clean, unlimited and free. In this Paper we are design a micro-grid model by using PV cell with help of boot converter. This model is basically applicable in rural or islanded load system. Here we also discussing the operation of autonomous or grid connected microgrid model by using PV cell with help of Boost converter. PV model is completed by using MATLAB SIMULINK and different current Voltage and power levels. The MATLAB SIMULINK is done in island mode as well as grid-connected mode at the both end, grid end and load end. This study aims to understand the change of fault value Compared to healthy surgery that may serve as a cornerstone Selection of protection strategies that may work effectively both operating modes.
