Improvement of Domestic Supply by Interfacing with Solar Photovoltaic Electric Power System

This paper investigated the possibility of interfacing the solar photovoltaic (PV) electrical energy to the domestic electric power transmitted and distributed. The domestic electric power supply was converted to DC electric power supply to obtain the same frequency and angle difference with solar PV power source, having the same frequencies and phase differences both sources were paralleled as to increase voltage output. MATLAB was used to simulate both sources with the aim of increasing the total power supply. Results show that the domestic power supply of 62.5kVA and PV solar power supply of 6.25kVA were synchronized to obtain 68.75kVA at 220V AC power, increasing the domestic power supplied to 9.1%. At cloudy weather, dip cells and charge controller are recommended to improve the solar PV electrical power generated. From the work, the combined output of both power from the domestic and solar PV generated enhance the total power supplied. At the point of domestic power failure, the solar PV power generated sustained the essential loads only in operation while the non-essential loads will automatically be switched off. It is strongly recommended that the Solar PV power source should be encouraged as an alternative means of power generation to reduce both non renewable source of power generation and environmental pollution.
