Optimal location decision of wind generators in urban areas using multi criteria techniques.

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.
