Technical Aspects of Mini-Grids for Rural Electrification

Abstract

This chapter aims to provide an overview of the main technical options and decision points that arise when developing a plan for a rural mini-grid. It begins by considering the four potential sources of renewable energy—water, sun, wind and biomass. For each the relevant technologies and methods for quantifying the available resource are considered. Key options for the system architecture are then covered including the choice of AC or DC distribution, network topology, hybrid or single generator systems, and battery technology. Finally, the critical technical factors in system management are summarised.
