Stochastic approach in study of the effects of photovoltaic sources upon power distribution networks

Issues regarding the influence of the presence of sources of electricity generation, based on renewable resources, the facilities for transportation, distribution and consumption of energy are varied. The effects are more pronounced in the case of solar and wind power, given the specific and variable intermittent electricity production. This paper refers to the effects of the solar sources of power losses on the power grid, resorting to a stochastic approach, motivated by the variability, randomly, to several dimensions, such as pregnancy and solar radiation. It stresses the need for such an approach, then, presents the mathematical model used. The case study presents the results of measurements taken and the results of simulations. The last part contains the conclusions of the study conducted.
