Comparing top-down and bottom-up approaches for integrated electrification planning.
Abstract
The article discusses the challenges of electricity access in developing countries and the importance of integrated electrification planning. It introduces a novel top-down computational approach to identify the least-cost electrification mode for consumers. The methodology involves partitioning the network to determine grid-extension and off-grid microgrid clusters. Sensitivity analyses on fuel cost and grid reliability show that the top-down method leads to lower system costs at higher reliability and fuel cost values. Results from both approaches have significant overlap in recommendations with similar cost values.
