Comparison study of different dynamic battery model

The storage systems are intended to achieve energy management of the photovoltaic system and batteries are the most important devices to build energy storage systems. So, to develop a photovoltaic system, developments need to be made, not only in energy conversion technologies, but also regarding the feasibility and capacity of energy storage systems. There are many technologies of batteries to improve the power quality and reliability of the power system. This paper carried out to discuss about four batteries technologies: Lithium-ion, Lead-acid, Nickel-Cadmium and nickel-metal hydride. In fact, it gives a digest description of these batteries and proposes an easy mathematical model of every one of these dynamic batteries. Finally, a comparison between the different types of batteries and a suggestion of the most suitable photovoltaic's battery technology are presented.
