Abstract

Connecting remote and isolated communities to the national grid is difficult and expensive. This is due to the geographic locations of these isolated communities and terrain that needs navigation when installing transmission lines to transmit power to the communities. This paper presents a case study of the design of a hybrid energy system for electrification of a remote region in South Africa. Upper blink water is about 20km away from the national grid. An effort has been made to design hybrid energy system which consists of solar photovoltaic (PV), diesel generator and battery storage. Homer software is used to evaluate the technical characteristics and efficiency of the proposed hybrid energy system. Reticmaster software is used to calculate the voltage drops of distribution lines to the residential houses of the communities. The results show that it is feasible to supply the isolated community with the proposed hybrid energy system. The average electricity cost is R110.93c/kWh and the amount of diesel fuel per year is 16685L/year.
