“…The typical power curve of a 10-kW pitch-controlled WT is shown in Figure 3(a), while the power curves using the six selected pitch-controlled WT of 10 kW rated capacity are plotted in Figure 3(b). As a result of the pitch regulated systems, the voltage of the electricity at which pitch-controlled WT generate power at WS above their rated levels, does not decrease [36]. Four different zones are observed in this curve (Figure 3(a)).…”

This study aimed at investigating the characteristics of the wind power resource in the Far North Region of Cameroon (FNR), based on modelling of daily long-term satellite-derived data (2005-2020) and in-situ wind measurements data (1987-2020). Five different reliable statistical indicators assessed the accuracy level for the goodness-of-fit tests of satellite-derived data. The two-parameter Weibull distribution function using the energy factor method described the statistical distribution of wind speed and investigated the characteristics of the wind power resource. Six 10-kW pitch-controlled wind turbines (WT) evaluated the power output, energy and water produced. A 50 m pumping head was considered to estimate seasonal variations of volumetric flow rates and costs of water produced. The results revealed that the wind resource in FNR is suitable only for wind pumping applications. Based on the hydraulic requirements for wind pumps, mechanical wind pumping system can be the most cost-effective option of wind pumping technologies in FNR. However, based on the estimated capacity factors of selected WT, wind electric pumping system can be acceptable for only four out of twenty-one sites in FNR.

“…Therefore, the energy obtained from the wind will depend not only on the average wind speed and the turbine characteristics, but also on the contribution of each wind speed ranges. Usually the Weibull distribution is used (Mathew, 2006;Secci, 2012, 2014). It can be defined as (Pishgar-Komleh et al, 2015):…”

Doi: https://doi.org/10.18273/revuin.v17n1-2018014 Vol. 17, no. 1, pp. 155-162, enero-junio 2018 Revista UIS Ingenierías RESUMENEste artículo analiza el impacto que tienen las plantas de generación fotovoltaica y eólica en el precio del mercado Spot cuando se tiene un modelo de despacho de energía no liberalizado y se usa una estrategia de despacho que da beneficios a las plantas renovables, permitiéndoles despachar con un precio de oferta igual a cero. La técnica de Replicator Dynamics usa la utilidad marginal de las plantas para optimizar el despacho, llegando al óptimo cuando las plantas alcanzan la misma utilidad marginal. El estudio también incluye la representación estocástica de la velocidad del viento y la radiación solar para analizar las variaciones en la utilidad marginal cuando se tiene generación eólica, cuando se tienen generación fotovoltaica y cuando se incluyen los dos sistemas de generación de forma simultánea. Los resultados indican que la estrategia de despacho genera variaciones hasta de un 21.9% en la utilidad marginal, afectando a las plantas en firme con reducciones de hasta un 58.6% en la potencia despachada cuando se tiene únicamente Generación Fotovoltaica e incluso haciendo que disminuya a cero cuando se tiene generación eólica.PALABRAS CLAVE: Despacho de potencia; mercado spot; análisis estocástico; generación fotovoltaica; generación eólica. ABSTRACTThis paper analyzes the impact of photovoltaic and wind power plants on the price of Spot market, when a nonliberalized energy market and a profit-based dispatch strategy for renewable plants are used, that allow them dispatching the power at an offer price equal to zero. The Replicator Dynamics technique uses marginal utility of the power plants to optimize the dispatch, reaching the optimal when marginal utility of the plants become equal. The study also includes stochastic representation for wind velocity and solar radiation to analyze the variations in the marginal utility for three cases: including wind power plants, including photovoltaic power plants, and including both
