STUDY ON OPTIMAL CONFIGURATION FOR GRID-CONNECTED SOLAR ENERGY SYSTEM

Abstract

In this study, the optimal configuration for a 28 kW ground-mounted solar power system is calculated and selected based on consideration of two conditions, namely power supply reliability and optimization of power generation efficiency into the grid. The system consists of photovoltaic power source connected to the grid through inverters, calculations combined with PVSyst simulation software have been done to select the optimal angle and direction of the battery system. After that, the study on the power generation efficiency of different battery coupling models for REC Si-poly 350 Wp and REC Si-poly 280 Wp batteries has been implemented so that the most optimal configuration is chosen. In addition, the loss in operation is also analyzed, the efficiency and energy emitted from the solar power system are completely compatible with the characteristics of the photovoltaic battery system. The results of this research are to optimize the grid-connected solar power system, considering the load model with the condition of optimizing the efficiency, economic efficiency and reliability of power supply. Also, they can be applied for a preliminary assessment of the specifications and performance of a real project.
