An improved dynamic battery model suitable for photovoltaic applications

Modeling of batteries used in photovoltaic applications has been a real issue for many research groups due to its complex electrochemical and electrical behavior. In this paper, we propose an improvement of the Battery model by identification of all parameters in order to estimate the different areas of Battery´s output voltage in real conditions for PV systems. For this purpose, we also performed both static and dynamic simulation. Comparison with real measurement has shown good agreement with the simulation.
