Design and Implementation of Off-Grid Systems

Abstract

This chapter considers the design and implementation of off-grid electrical systems in developing countries. The life cycle of a mini-grid is presented, from the initial decision to develop a mini-grid to site assessment and the final decommissioning or expansion. Considerations when selecting whether to use conventional or biomass-fueled generator sets, solar arrays, wind turbines, or micro hydro power are discussed. A realistic in-depth design example is provided. Design of the distribution system is discussed. The chapter concludes with economic considerations and case studies of off-grid systems in Haiti, Tanzania, and Zambia.
