Abstract

The dynamic simulation of a hybrid power system that combines solar energy and the traditional power supply system to ensure reliable and sustainable power supply for a shop in Nigeria that provides community cellphone charging services is presented in this paper. The name of the supermarket is Better Mart, and it is located at Remlek Bus stop Badore, Ajah Lagos State, Nigeria which is known for consistent power outages. The designed hybrid power system at Better Mart consists of 240 pieces of Trina Duomax PEG14 PV panels with a rated capacity of 320 Watts each and a total of 76.8 kW which is connected to a 360 VDC bus, 50 kVA Caterpillar generator that runs on diesel, Grid system, 24 kW Fronious Symo Inverter and 30 pieces of each 12 V/220 Ahr EnerSys PowerSafe SBS 1800 battery storage. The sizing of the designed system was carried out with Homer Pro software while the dynamic simulation was done in MATLAB Simulink environment. The dynamic model of the system is fast and accurate as can be seen from the MATLAB simulation results.
