“…It is necessary to know the local wind velocity not only for the design of devices related to wind energy (such as determining the most suitable turbine for the available wind resource in a specific region and analysing the optimal amount of wind generators [9], or for the multivariate control of wind turbines [10]), but also for other different situations such as solar collectors, biotic pump modelling or the evaluation of evaporation losses in swimming pools [11] [12] [13]. Studies have been carried out to estimate the wind potential of several cities, characterizing the wind velocity in a statistical manner, using the Weibull probability distribution to implement urban wind turbines [14]; however, within a zone, there are different profiles for wind velocities, which generates the need for the evaluation of the wind potential at the micro-local level.…”

The research deals with the estimation of the available wind's potential on the building terrace, at the P-headquarter of the Universidad ECCI of Colombia, and from the results obtained consequently verify if the wind conditions are conducive to the operation of a wind micro-turbine, currently unused. The methodology is based on the wind speed estimation; applying the velocity potential's law to the records captured, between the 1st of January and the 24th of March, 2015, by the weather station of the National University of Colombia. Once the speed of the wind is estimated in the study area, a frequency velocity distribution is performed and the graphical method is applied to determine the scale and shape parameters that allow the characterization of the function of the Weibull distribution in the study area. Finally, based on the micro turbine's specifications, the power that could be usable is estimated and it is theoretically evaluated if the wind conditions are optimal for its operation. Although wind speed data were recorded in the study area, using the Universidad ECCI weather station, they were only used as a benchmark for the estimated velocities. The estimated values of the useful power and the wind power density for the wind micro-turbine, operating at a wind speed of 4.0m/s, which represents approximately the average value of the wind speed ResumenLa investigación consiste en estimar el potencial eólico disponible en la terraza del edificio, sede P de la Universidad ECCI y verificar, a partir de los resultados obtenidos, sí las condiciones de viento son propicias para el funcionamiento de una microturbina eólica, actualmente inutilizada. La metodología se fundamenta en la estimación de velocidad de viento; aplicando la ley potencial a los registros de velocidades capturados, entre el 1 de enero y el 24 de marzo de 2015, por la estación meteorológica de la Universidad Nacional. Una vez estimada la velocidad de viento en la zona de estudio, se realiza una distribución de velocidades de frecuencia y se procede, aplicando el método gráfico, a determinar los parámetros de escala y de forma que permiten caracterizar la función de distribución de Weibull en la zona de estudio. Finalmente y a partir de algunas especificaciones de la micro-turbina, se estima su potencia útil y se evalúa, teóricamente, si las condiciones de viento son óptimas para su funcionamiento. Aunque se registraron datos de velocidad de viento en la zona de estudio empleando la estación meteorológica de la Universidad ECCI, únicamente fueron utilizados como patrón de comparación para las velocidades estimadas. Los valores estimados de la potencia útil y la densidad de potencia del viento, para la micro-turbina eólica, operando a un velocidad de viento de 4.0m/s, que representa aproximadamente el valor promedio de la velocidad de viento (obtenido con el factor de escala de la función de Weibull), son respectivamente 41 W y 0.226 W/m 2 .

“…This software works by selecting a number of possible combinations of solar PV modules, batteries and inverters. The disadvantage of this tool is that only provides generated power, and for recent works it is used as a tool for cost optimization [5]; however, it does not provide the optimal configuration of the PV modules and then it took a long time for the solution [6].…”

Electric power is a necessity for the development of a society, without it would be impossible to see the world as we actually know. Its use is closely related to modern life and human development. Renewable energy is a good alternative for energy supply in regions where conventional power networks are absent or service quality is intermittent. The importance of these renewable energy sources lies in their lower emissions of carbon dioxide (CO2) to atmosphere and the reduced dependency on raw materials for importation and transport for power generation. Renewable energy is becoming economically competitive in the short to medium term. Hybrid power systems is a novel approach recently gaining popularity, since they combine multiple sources of renewable energy such as solar, wind, mini hydro-power, and also could include conventional generators as support. This combination allows the optimization of the power generation system by reducing emissions from the petroleum and coal based energy sources. This paper presents a pilot hybrid power system design for the power supply in the hotel 'La mansion' in the town of Acacias, Meta (Colombia). Simulation and optimization were based on a computer program known as HOGA educational version 2.2, which initially considered economic parameters associated to photovoltaic system such as: overall power, replacement cost and operation and maintenance costs, as well as all powers to consider in the simulation. The main purpose is to present an alternative power source in the hotel located in an area with high rates of power outages, and gradually include photovoltaic solar power combined with conventional energy supply, to meet the energy demand when the peak consumption periods occurs during power outages from the power grid. This paper confirmed that hybrid power systems are a good energy supply alternative as auxiliary small power systems because they are capable of supplying the power demands during power grid outages or even in total absence of the power grid. Simulations showed that the combination of diesel and solar photovoltaics is a good alternative to meet lighting power demand in the hotel 'La Mansion', even in night hours thanks to the battery storage.

“…The electric current generated from solar photovoltaic energy currently has a variety of applications, primarily in isolated systems [2] and systems connected to the grid, called grid-tied systems [3]. The focus of this study is gridtied systems for a nominal 1 kW installation.…”
