Abstract

AbstractRural electrification is often considered to be the backbone of the rural economy. In spite of launching of ambitious schemes to achieve 100% rural electrification, millions of people, particularly in rural areas are away from grid electricity and its benefits. Renewable energy sources (RES) coupled with pumped storage provides a technically viable solution for continuous power supply in remote areas. Therefore, this paper presents a solar-wind hybrid system with pumped storage generation unit to meet the basic load demands of domestic consumers, using Pico hydro turbine (PHT). A prototype of this system is developed in the laboratory and investigates its operational aspects. This scheme utilizes a PHT (300 W), usually employed in run-off river schemes, in domestic level application. The developed model is evaluated on sunny and cloudy day. It operates on a daily basis, storing the surplus energy from renewable sources by pumping water to an upper reservoir, and retrieve this energy through its PHT. Therefore, this system satisfies the basic load demands of domestic consumers who are away from access to the grid. The control and energy management of the proposed system is carried out using labVIEW.
