Effective Utilization of Pv and Battery Based System For Telecom Load

<p>One of the major sectors which have seen a rapid growth in the last decade is mobile telecommunications. It has not only become an important part in peoples lives but also playing a part in world business as the entire world is connected by telecommunication networks. The growing power demand and the dwindling fossil fuels resulted in the unreliable power supply which is the critical challenge facing by telecommunication industries. Currently telecom towers are using Diesel Generators (DG) as source of supply which is rather expensive and emits environmental pollutants. This study analyses the solar photovoltaic (PV) system and battery based hybrid power supply system to reduce the usage of DG. The effective utilization and management of the PV and Battery sources increases the efficiency and reliability of the system. Therefore in this work a literature review related to maximum power point tracking of PV array Li-Ion battery aging mechanism and battery state of health (SoH) estimation techniques have been presented.</p>
