| dc.description.abstract | In Ethiopia, the electric sector is already experiencing considerable rising in generation of power from renewable energy sources like the GERD. Large amounts of new generation are expected in the near-term future, which will require additional distribution planning to properly integrate these resources into the existing electric power supply system. The Distribution expansion planning has an important role in this environment to guarantee the security of the supply with the required levels of quality and price. Therefore, the realization of new distribution lines must be fast and accurate to avoid delays to connect new power sources and potential supply and reliability problems. In this sense, Geographical Information Systems (GIS) can be a powerful tool that provides decision support techniques, which enables a transparent, sustainable, faster and cheaper planning process for in power distribution systems. Manual approach electric line routing based on paper maps, aerial photographs and field visits can generate inconsistent results, besides being a time consuming and intensive labor activity. The application of methodologies based on geographic information system (GIS) combined with multi-criteria assessment (MCA) methods are applied for this study and have proved to be less time taking and cost savings on the electric line planning step. For this Aba-Samuel substation supply area is studied and lower length and lower total cost route is generated via densification and intensification analysis. For route selection, criteria’s like proximity to road, land use land cover and household density are considered. ODK data collection method is used to collect primary data. | en_US |
