The lack of access to electricity in developing countries necessitates spatial electricity planning for guiding sustainable electrification projects that evaluate the costs of centralized systems vis-a-vis decentralized approaches. Heuristic approaches have been widely used in such electrification problems to find feasible, cost effective solutions; however, most of the time global optimality of these solutions is not guaranteed. Our thesis through its modeling approach provides a new methodology to find the least cost solution to this electrification problem. We model the spatial network planning problem as Prize Collecting Steiner Tree problem which would be base for a decision support tool for rural electrification. This new method is systematically assessed using both randomly generated data and real data from rural regions across SubSaharan Africa. Comparative results for the proposed approach and a widely used heuristic method are presented based on computational experiments. Additionally, a bi-objective approach that permits to take carbon emission level into the account is implemented and experimented with numerical data.

“…Ter-Gazarian and Kagan [11] design a model that sizes and locates the generation and storage equipment, but only considering one microgrid without individual systems. VIPOR [12] draws on the results from HOMER [13] to design the distribution system combining microgrids and individual systems, but does not consider different energy resources for the individual systems and does not include voltage drops. Finally, Ferrer-Martí et al [14] develop a mathematical model for designing stand-alone electrification systems with wind-PV technologies, considering the detail of the energy resources, the energy and power demands at each consumption point and obtaining, as a solution, the emplacement of all the equipment to implement, and the adequate combination of microgrids (with their structure) and individual systems.…”

Including management and security of supply constraints for designing stand-alone electrification systems in developing countries

Hybrid wind-photovoltaic stand-alone systems have proven to be suitable to electrify isolated communities autonomously. Moreover, the use of a combination of microgrids and individual systems has been demonstrated to be very adequate. There are a few tools to assist their design but they only consider economical and technical characteristics. However, the management of the system and the security of supply, both at a community level, are key aspects to design appropriate electrification systems for end-users, thus ensuring projects' long-term sustainability, especially in rural areas of developing countries. In this context, this paper develops a mathematical model to optimise the design of wind-photovoltaic projects combining microgrids and individual systems, and including the aforesaid key issues as constraints. Thus, the aim is to minimise the cost while meeting the technical but also the management and the security of supply constraints. Finally a validation is carried out in the real community of Alto Peru (Peru), proving that the two studied aspects allow obtaining electrification solutions with some benefits that strongly compensate the obtained slight cost increases.

When electrifying isolated rural communities, usually standardized solutions have been implemented using the same technology at all the points. However these solutions are not always appropriate to the community and its population. This article aims to describe the technical design of the electrification system of the community of Alto Peru (in the region of Cajamarca, Peru), where the adequate technology was used at each area according to micro-scale resource evaluation and the socioeconomic requirements of the population. Specifically four technologies were implemented: wind microgrids in highlands, a micro-hydro power plant in the presence of a waterfall, a PV microgrid in a group of points sheltered from the wind and individual PV systems in scattered points with low wind potential. This project brought electricity to 58 households, a health center, a school, a church, two restaurants and two shops.
