Planejamento e dimensionamento de usinas híbridas eólico-solares conectadas ao SIN

Abstract

Unlike dispatchable energy sources, non-dispatchable renewable energy sources, such as wind and solar, present uncertainties that demand the forecast of energy production, creating a set of challenges for the planning and operation of electrical systems. This is mainly due to its primary resources, wind and solar radiation, presenting an intermittent behavior depending on climatic conditions. The hybridization of these electric power generators using their complementarity characteristics can contribute significantly to mitigate this problem by providing a more stable power over time. Thus, this work aims to evaluate, through Pearson's coefficient, the hybridization potential of hybrid and associated wind-solar plants, fictitious, located in the Paulino Neves/Barreirinhas region in the state of Maranhão, as well as to propose a methodology using algorithms genetic tests to determine their optimal compositions. The results indicated that there is not a predominantly complementary behavior of the generations of these sources in the studied place. In addition, the optimal composition of the Hybrid Plant is 95% wind installed power and 5% solar, and the Associated Power Plant is 95.77% wind installed power and 4.22% solar installed power.
