Abstract
This work analyzes the complementarity of energy production from solar-wind power plants, intending to optimize a hybrid power plant that results in a more uniform generation and can meet the energy demand. For the study, it was considered that the hybrid plant is located in the state of Rio Grande do Norte, using a climate database in the Typical Meteorological Year format referring to this location. Complementary analyzes were carried out for three years, from 2017 to 2019. In the analysis of temporal complementarity, the Pearson Correlation Coefficient (PCC) was used, and an algorithm was developed in the MATLAB software that performs the temporal analysis. Three temporal analyzes were carried out: (i) analysis of the complementarity of energy production between wind and solar resources over the three years; (ii) analysis of the daily complementarity of wind and solar energy production; (iii) analysis of the complementarity between total energy production and energy demand in the region. As a result, the PCC of wind and solar energy production over three years is 0.5723. The average complementarity of solar and wind energy production over a day is 0.6157. This indicates a positively moderate relationship, which indicates that the production of wind and solar energy have similar behavior in the study region. In the optimization analysis of a plant, the configuration that presented the best complementarity with energy demand was that of a solar plant.
