Abstract
The northeast region of Brazil is rich in solar and wind resources, which means that this region has great potential for generating electricity through these sources. Knowing that these sources, as well as water resources, have a seasonal behavior, it is of great importance to study their correlation. Knowing the standard behavior of wind-solar resources allows optimizing hybrid plants so that, even if one of the resources is low, the plant continues to produce the same amount of electricity without major variations. The objective of this work is to develop a map of the complementarity of solar-wind energy in Rio Grande do Norte in order to verify the relationship between both resources in several cities in the state. For the study, we used a climate database in the Typical Meteorological Year format referring to several points in this location. These data were used to estimate the energy generation from solar and wind sources, according to the base literature. In the temporal complementarity analysis, the Pearson Correlation Coefficient (PCC) was selected for data from a complete meteorological year, with the values of the calculated coefficients applied in the temporal analyses. At the end of the study, it was concluded that more than half of the cities analyzed have the minimum of complementarity between renewable resources, and the city that has the highest level of complementarity is Vera Cruz with a PCC of 0.6704.
