Abstract

Energy system planning becomes essential in order to match demand and supply, where cost minimization is a primary objective. In addition, it is also of great significance in assessing the proper mix of energy sources so that energy systems meet the given load profile in a most efficient and cost-effective way. Lately, climate change has brought an increased amount of challenge for energy systems planners. As a result, there are varieties of planning methods and tools available today, either commercially or noncommercially. However, from the literature it is evident that most of these tools are targeted primarily for the developed world, thus leaving the developing world behind, where the energy issue is even more critical. Hence, the principal focus of this article is on the study of rural energy systems planning tools that have been developed so far and an assessment of their features. In a nutshell, this article presents a background review on rural electrification studies from the perspective of available planning and modeling tools. First, an overview of the energy models and their classifications are briefly discussed in general. Afterward, various rural energy models developed so far are reviewed. This review article will give a quick and broad picture of rural energy models and assist researchers, policy makers, and energy planners who are working with energy systems in the developing world.
