    Abstract: The effect of variation on optimal decision variables with respect to unit cost of fuel (sensitivity analysis) for optimal performance of 100MW Delta IV ughelli gas turbine power plant unit was determined using optimal operating parameters and exergoeconomics. The optimization tool is an evolutionary algorithm known as Genetic Algorithm (GA). The c... Show More

    Abstract: In this paper, the degradation rate of monocrystalline, polycrystalline and amorphous PV modules is studied in a sub-Saharan zone in three periods: cleaning, no cleaning and rainy season. Studies that have been shown have increased series resistance. This is how the different cleaning phases of the crystalline module to the thin layer for not havin... Show More
