REALPE JIMENEZ, ALVARO; DIAZGRANADOS, JORGE A.  e  ACEVEDO MORANTES, MARÍA TERESA. ELECTRICITY GENERATION AND WIND POTENTIAL ASSESSMENT IN REGIONS OF COLOMBIA. Dyna rev.fac.nac.minas [online]. 2012, vol.79, n.171, pp.116-122. ISSN 0012-7353.

In this work, mathematical modeling and simulation of electricity generation from wind was carried out in regions which are not connected to the national electrical system grid, and have an annual mean wind velocity higher than 4 m/s at an altitude of 10 m. Seven different types of power turbines between 6 and 2,750 kW were studied in order to analyze their technical and economic feasibility. The Gachaneca (Boyaca) and the Sesquicentenario (San Andres Island) stations have an energy potential of 5,106 and 3,823 MWh/year, respectively, using a 2,750 kW turbine at an altitude of 70 m. The production cost of kWh for the two regions was found to be less than US$0.10 for turbines with a capacity higher than 1.0 MW. The energy produced can satisfy the electricity needs of Colombian islands such as San Andres or Providencia.

Palavras-chave : wind energy; renewable energy; wind potential.
