    Identifying locations for electric vehicle charging stations in urban areas through the application of multicriteria techniques
    (2024) Ochoa Correa, Danny Vinicio
    The incorporation of electric vehicles (EVs) into urban mobility is increasing daily, driving the need to incorporate urban charging stations (EVCSs) additionally. This study proposes a methodology for identifying adequate EVCS locations within an urban area. This methodology is based on the joint application of multicriteria decision-making methods (MCDMs) to solve urban planning problems related to the placement of EVCSs. As a starting point, the locations of the existing fossil fuel supply stations in each city are used as alternatives. The city of Cuenca, Ecuador, is used as a case study. Criteria and subcriteria have also been determined based on the available information and are used to propose three scenarios based on their value variation, which is established as preponderance weights. Among the results obtained, three alternatives scored better than the rest in most of the evaluations. As there was no conclusive result, a statistical analysis was conducted to strengthen the decision-making process and determine the most favourable potential locations.

    Optimal location decision of wind generators in urban areas using multi criteria techniques
    (2020) Morocho Dominguez, Edwin Santiago; Morocho Chicaiza, Wilson Giovanny; Barragán Escandón, Edgar Antonio; Zalamea León, Esteban Felipe
    The inclusion of urban energy self-supply alternatives is an optimal condition to face the growth trend in energy infrastructures and nature impact as its consequence. Powering the urban grid including wind turbines inner the urban boundaries In Cuenca, Ecuador as case study have been analysed in this research. This city and its surroundings possess an average annual wind speed of 4 to 5 m / s, depending on different spots conditions, altitude and site characteristics. The PROMETHEE method is used to figure out the best suitable area to take advantage of the wind source for electric power in ranges less than 10KW (micro-scale). Four sites are determined as suitable alternatives, and they are evaluated based on sets of technical, economic, environmental and social criteria. For a more reliable solution, we propose three different scenarios based on different weighting methods. As consequence, the Turi location turns out to be the best option because geographical and wind conditions at the zone. However, it is necessary to analyze aspects related to visual and environmental impact for an adequate implementation of this type of projects. © European Association for the Development of Renewable Energy, Environment and Power Quality (EA4EPQ).
