本文分析了巴西南部电力系统中风电高渗透水平的主要影响。为此，巴西南方电力系统的每小时运行模拟使用经济调度模型。两个主要的场景进行了探讨：基线和风力穿透的情况下，无论是2030年和2050年。为了创建这些场景，来自集成能量模型的结果被用作调度模型的输入。经济调度模型导致了一些预期的结果，如系统发电成本的降低，温室气体排放的减少，以及在风力发电的情况下更需要输电扩展。结果还表明，即使是一个灵活的电力系统在巴西南部，风电渗透的影响，可以观察到。此外，研究结果表明，设置火电厂提供二次备用，可以潜在地提高水电系统的平衡管理。最后，从连接的经济调度模型和综合能源模型的结果表明，需要更好地结合能源扩展模型与电力调度模型，考虑到操作和传输系统的限制，以具有稳定和可行的机组组合计划。(C)2019爱思唯尔有限公司版权所有。
This paper analyzes the main impacts of high penetration levels of wind power in the power system of Southern Brazil. For this, an hourly operation of the Brazilian Southern power system is simulated using an Economic Dispatch Model. Two main scenarios are explored: a baseline and a wind penetration case, both for 2030 and 2050. To create these scenarios, results from an Integrated Energy Model are used as inputs for the dispatch model. The economic dispatch modeling led to some expected outcomes, such as a reduction in the system generation cost, a reduction in greenhouse-gas emissions, and a greater need for transmission expansion in the wind-power scenarios. Results also show that, even for a power system as flexible as the one in Southern Brazil, wind power penetration impacts can be observed. Moreover, results show that setting thermal power plants to provide secondary reserve can potentially improve the balancing management in hydropower-based systems. Finally, results from linking the Economic Dispatch Model and the Integrated Energy Model showed the need for better combining energy expansion models with power dispatch models that consider both the operation and the transmission system restrictions, in order to have stable and feasible unit commitment schedules.
