ABSTRACT

Several countries face the challenge of reducing the intermittency of solar photovoltaic generation due to changes in climatic conditions. Considering that Brazil has continental-scale dimensions and diverse geography, an alternative that allows the smoothing of the intermittency of solar photovoltaic generation is needed. The novelty of this study is the proposal to efficiently allocate the production of photovoltaic solar energy between the interconnected regions of the country, forming an optimal portfolio with the highest productivity and the least intermittency. Thus, the regional allocation process for solar generation is formulated through an optimization problem with two objective functions: to increase the country’s productivity and simultaneously control the variability of the supply of solar energy. This study concludes that the current models of planning for the expansion of Brazil do not consider the variability of solar irradiation incident in the five regions of Brazil.

摘要

由于气候条件的变化，一些国家面临着减少太阳能光伏发电间歇性的挑战。考虑到巴西具有大陆尺度的维度和多样化的地理，需要一种可以平滑太阳能光伏发电间歇性的替代方案。这项研究的新颖之处在于建议在该国相互连接的地区之间有效地分配光伏太阳能的生产，形成具有最高生产力和最少间歇性的最佳投资组合。因此，太阳能发电的区域分配过程是通过具有两个目标函数的优化问题制定的：提高国家的生产力，同时控制太阳能供应的可变性。
