In this study, a grid connected PV system to a realistic HTA grid model is presented in details. Objectives: The main objective is the technical and quality evaluation of the grid integration of a 500 KW Photovoltaic station into a finite power grid model. Methods/Statistical Analysis: Two tasks are expected to be performed; firstly, the injection of maximum PV power return into Point Of Connection (POC) although respecting the tolerable variation in terms of voltage levels based on grid code. Undeniably, this amounts to simulate the suggested system with real components under a sudden climatic change. Findings: Therefore, performed studies may reveal power quality concerns, unlike the infinite impedance models of point of connection or the equivalent utility grid. Secondly, the flowing power quality and voltage levels are controlled at anytime and anywhere, through the grid. For this, we developed mathematical models of each part of the system from the PV arrays to the grid. This step allowed us to study the dynamic stability, then to establish suitable regulation and control laws for the DC/DC and DC/AC converters and finally to simulate the electrical signals from production to distribution by using MATLAB/SIMULINK environment. Application/Improvements: We obtained good satisfaction ratios and acceptable voltage levels without storage units using optimal monitoring strategy based on optimal power extraction and exchange between the PV Generator, grid and loads.
