Abstract

A mobile telecommunication sector has experienced a rapid growth in Libya and Al-Madar Al-Jadid is one of largest companies providing services in this sector. Currently, PV systems are widely used for powering remote GSM communication stations in the country and number of Al-Madar Al-Jadid communication stations powered by such stand-alone PV systems was about 135 in 2009. A Simulink Matlab model was built to dynamically simulate the operation of the stand alone PV system powering one of Al Madar Al Jadid remote communication stations in desert conditions, taking into account variation of insolation and ambient temperature during a day. The results of mathematical modelling on the producible and produced power, charging and discharging battery power and the state of charge of the battery bank are in a good agreement with real experimental data recorded on the station with the use of a data-logger. Results obtained clearly indicated that the existing system, including PV panels and the electrical storage, is excessively large for the current electrical demand on the station and therefore could be reduced in the size by a factor of two.
