摘要

分布式可再生能源的大规模整合是当前电力系统的现实。在这种发电侧波动较大的新情况下,需要合并新的资产,为系统提供额外的灵活性,以容纳尽可能多的可再生资源。在这些新资产中,直流或交流柔性链路可以在管理径向配电系统中的潮流中发挥关键作用。它们连接在配电馈线之间,可以以可控的方式调节有功潮流,并有助于网络电压支撑。然而,这些设备的功率损耗可能是某些功能的限制因素。本文集成了用于最优潮流算法的几种柔性链路拓扑的详细功率损耗模型,目的是评估其对这些设备功能的影响。这样,就可以通过一些关键的性能指标,对不同的直流和交流柔性链路的性能进行定量的基准测试。本文提出了一个基于欧洲MV基准的案例研究,该基准具有可再生能源的高渗透率,以证明灵活链接可能提供的好处和局限性。

Performance Assessment of Flexible Links in Distribution Networks Using a Detailed Power Losses Model
The massive integration of distributed renewable energy resources is a reality in the current power system. In this new context with a greater volatility on the generation side it is required to incorporate new assets to provide additional flexibility to the system to accommodate as much renewable resources as possible. Among these new assets, DC or AC flexible links could play a key role in managing the power flows within radial distribution systems. These connected between distribution feeders may regulate the active power flow in a controlled manner and contribute to the network voltage support. However, the power losses of these devices can be a limiting factor of some functionalities. This paper integrates a detailed power loss model of several flexible link topologies for Optimal Power Flow algorithms with the aim of evaluating its impact on the functionalities of these devices. In this way, it is possible to benchmark the performance of different DC and AC flexible links in a quantitative manner by means of some key performance indexes. The paper proposes a case study based on the European MV benchmark with a high penetration of renewable energy sources to evidence the benefits and limitations that flexible links may provide.
