Abstract

The stand-alone solar photovoltaic system has different kinds like on-grid and off-grid. This paper deals with the analysis, design and control of electric energy with different load profiles in off-grid stand-alone solar photovoltaic systems. The management of electric energy varies according to various load profiles. In here, the loads are considered as only DC loads. This paper shows three different dc load profiles. The goal of the management is to show and control the loads according to the load profiles and observe the outputs in MATLAB/Simulink. The simulation of the system has been developed in MATLAB/Simulink. Here, a simple stand-alone solar photovoltaic model has been used which carries PV module, charge controller, management strategy, battery, loads and a monitoring box to monitor the load profiles. This work introduces the procedure of how to control with different load profiles and what are the outputs. Finally, experimental results and related figures are shown to verify the effectiveness of the proposed energy management strategy. Keywords: Stand-alone System, Management, Solar cell, MPPT, Energy, PV
