Abstract

The increasing penetration of variable renewable energy (VRE) generation along with the decommissioning of conventional power plants in Chile, has raised several operational challenges in the Chilean National Power Grid (NPG), including transmission congestion and VRE curtailment. To mitigate these limitations, an innovative virtual transmission solution based on battery energy storage systems (BESSs), known as grid booster (GB), has been proposed to increase the capacity of the main 500 kV corridor of the NPG. This paper analyzes the dynamic performance of the GB using a wide-area electromagnetic transient (EMT) model of the NPG. The GB project, composed of two 500 MVA BESS units at each extreme of the 500 kV corridor, allows increasing the transmission capacity for 15 min during N-1 contingencies, overcoming transmission limitations under normal operation conditions while maintaining system stability during faults. The dynamic behavior of the GB is also analyzed to control power flow as well as voltage stability. The results show that the GB is an effective solution to allow greater penetration of VRE generation while maintaining system stability in the NPG.

基于电池储能系统的虚拟输电解决方案提升输电能力

随着智利可再生能源（VRE）发电渗透率的不断提高以及传统发电厂的退役，智利国家电网（NPG）面临着一些运营挑战，包括输电拥堵和可再生能源削减。为了缓解这些限制，有人提出了一种基于电池储能系统（BESS）的创新型虚拟输电解决方案，即电网升压器（GB），以提高国家电网 500 千伏主通道的容量。本文利用 NPG 的广域电磁暂态 (EMT) 模型分析了 GB 的动态性能。GB 项目由位于 500 千伏走廊两端的两个 500 兆伏安 BESS 单元组成，可在 N-1 突发事件期间将输电容量提高 15 分钟，克服正常运行条件下的输电限制，同时在故障期间保持系统稳定。此外，还对 GB 的动态行为进行了分析，以控制功率流和电压稳定性。结果表明，GB 是一种有效的解决方案，既能提高 VRE 发电的渗透率，又能保持 NPG 的系统稳定性。
