Performance Analysis of an Installed 1.5kva Hybrid Power Supply

Abstract

This work models a 1.5KVA grid connected solar power supply system using a combination of PV array, charge controller, inverter, battery bank, A.C load and installation accessories which work complementarily to capture the best feature of the energy resources and provide the grid-connected location with the highest electricity network quality and reliability. The system operate at minimum running cost, population free environment, noiseless, reliable and provide the convenient of a twenty-four hour power supply. With this system, energy efficiency is achieved by lowering demand using demand response, incorporating temporary and permanent load shifting by back-up and parallel mode respectively. The system was installed at the administrative office of the head of department, electrical and electronic engineering department in Cross River University of technology, Calabar, Nigeria. The total energy is obtained by direct inspection and energy audit. The optimization of the system is based on numerical and analytical modelling and HOMER software package. The sizing results suggest that HOMER software is a powerful, efficient and flexible tool that gives the optimum and cost effective system based on renewable source.
