Hybrid Renewal Energy Systems for Rural Sustainable House Buildings

Abstract

In rural areas currently 2 billion peoples world- wide live without access to electricity .Grid extension is often highly costly and not feasible in isolated rural areas for the house hold uses. So such types of house building can provide centralized electricity generation at the local level using a village distribution network or house wise production and utilization. Such type mini grid project involves complex technical and financial issues. In this paper a critical and feasibility study of mini grid using renewable energy for the rural house building. The combination of renewable energy sources like solar energy ,wind energy and biogas energy selected for a hybrid system pushes for technology choices and there by economic situation of rural areas and also have cost effectiveness for long term, To increase efficiency gains and cost savings, priority given to sizing the system appropriately for the requirement. Solar photovoltaic is suitable for almost any location around the world and is also comparatively easy to install, maintain and scale up but the initial investment costs are higher than other technologies. Small wind power technology is very site specific, place to place variation of the source availability. Careful study is required before installing the wind power system. Biogas plants are very suitable for the rural houses that the biodegradable wastes are plenty. Along with these renewable energy systems storage batteries are integral component of hybrid system. Field studies and exhaustive demand analysis are a basic pre-requisite for the mini-grid for the electricity to the house building.
