Expansion

By the year 2019, the number of people without access to electricity was 770 million, most of which lived in rural areas. The currently models for rural electrification are often limited in their electrical analysis, or focus on a idealistic optimal solution whilst ignoring the real hierarchical topology of power systems. This work proposes a rural electrification strategy that makes use of Geographic Information System (GIS), graph theory and terrain analysis to create the best electric network topology.
The expansion and operation of water supply systems under growing demands, hydrologic variability, and water scarcity requires strategic decisions on supply sources for reducing and improving reliability and flexibility. The design and operation of such supply portfolio merits decisions of what and when to expand, and how much of each source to use considering interest rates, economies of scale and hydrologic variability.
