GONZALEZ-CABRERA, Nestor et al. Efficient method to integrate operational costs of wind generation into problem of the generation capacity expansion modelling. Ing. invest. y tecnol. [online]. 2022, vol.23, n.4, e1927.  Epub 01-Maio-2023. ISSN 2594-0732.  https://doi.org/10.22201/fi.25940732e.2022.23.4.029.

In this work, an efficient method to integrate the operating costs of the wind generation capacity, which includes the linearized electrical network is presented, the methodology consist in obtain a hypothetical hourly curve capable of representing the behavior of wind generators for their integration into the planning model of expansion of generation capacity. The implemented methodology showed efficient results by incorporating hypothetical hourly wind speed curves to the generation capacity expansion model, without the need to consider the probability distribution of wind speed, obtaining reduction in simulation times around 99 % with respect all overall expected year time, saving computational resources, and analyzing the behavior of wind generation and its economic implication in an electrical system. Finally, the model of the electrical network and the hypothetical hourly curve will be integrated into the planning model for the expansion of generation capacity and its technical-economic impact of considering various groupings for the modeling of the wind turbine is presented.
