Simplified dynamic models of photovoltaic/diesel generator/battery system using MATLAB line code are presented in this paper. The main purpose of these models is to predict the performance of photovoltaic/diesel generator/battery system through a specific time period. A complex battery model as well as the most recommended control strategies such as load following and cycle-charging dispatch are considered in the proposed models. Finally, the proposed models are validated using simulation and experimental data. Such models are helpful in studies related to hybrid photovoltaic/diesel generator/battery system control, sizing and performance assessments. (C) 2015 Elsevier Ltd. All rights reserved.
