Feasibility study of a hybrid PV-micro hydro system for rural electrification

Abstract: The present study investigates the possibility of using a stand-alone solar/micro hydro hybrid power system for low-cost electricity production which can satisfy the energy load requirements of a typical remote and isolated rural area. In this context, the optimal dimensions to improve the technical and economical performances of the hybrid system are determined according to the load energy requirements, the solar and water resources and the importance of supply continuity. The proposed system's installation and operating costs are simulated using the Hybrid Optimization Model for Electric Renewable (HOMER) with the stream flow, the solar radiation and the system components costs as inputs; and then compared with those of other supply options such as grid extension and diesel generation.

A survey of technologies increasing the viability of micro-hydropower as a cost-effective energy source for remote communities in South Africa

Abstract: This paper is a survey of technologies that increase the viability of micro-hydropower as a cost-effective energy source for remote communities. These technologies (civil, electrical, mechanical or electronic.) have helped in the development of micro-hydropower industry all over the world. They can be applied in rural areas not sevred by the grid to provide reliable and low cost energy. The motivation has been that there are a significant number of viable potential sites in isolated areas where micro hydropower is a realistic energy option, and where conventional schemes are not appropriate, especially in rural parts of South Africa.
