Abstract

Considering a system based on hydroelectricity, with a significant penetration of renewables (wind and solar) and high barriers to build new dams and reservoirs; this paper presents the benefits that the installation of pumped-storage power plants (PSP) could add to such system, improving its efficiency and respecting the expanding boundaries. A case study was developed considering sixteen hydroelectric plants from a real cascade, one equivalent PSP and five wind farms. Through an evolutionary algorithm, the PSP operation was optimized focusing on minimizing the spillage that could be used to generate power in a convenient moment. To prove this concept, three different hydrologic scenarios were analyzed: wet, dry and medium seasons; based on the real water inflow of the river, according to historical measurements. This investigation makes possible to conclude that a PSP can effectively reduce the effects of intermittency of wind and solar generation, optimizing a subsystem having a topological structure commonly found in the Brazilian Interconnected System.

抽水蓄能电站在面对高太阳能和风能资源参与时改善了巴西互联系统的运行

考虑一个以水力发电为基础的系统，可再生能源(风能和太阳能)的大量渗透，以及建造新水坝和水库的高障碍;本文介绍了抽水蓄能电站(PSP)的安装对该系统的好处，提高了其效率，并尊重了不断扩大的边界。一个案例研究考虑了16个真正的梯级水电站，一个等效的PSP和5个风力发电场。通过进化算法，优化了PSP操作，重点是最小化泄漏，可以在方便的时刻用于发电。为了证明这一概念，分析了三种不同的水文情景:湿季、干季和中季;根据河流的实际流入水量，根据历史测量。这项研究可以得出这样的结论:PSP可以有效地减少风能和太阳能发电的间歇性影响，优化具有巴西互联系统中常见的拓扑结构的子系统。
