在承受高压力且发电机与负荷之间存在较大距离的输电网络中，电压稳定性可能受到威胁。在与电压不稳定相关的紧急情况下，一种有前景的辅助对策是控制连接到中压和低压网络的大量分布式能源资源（DERs），使它们通过改变发电或消耗来局部减少净负荷。然而，在预期与传统电压调节器相互作用、跨变电站协调努力以及与DERs交换少量信息的同时实现这种控制是具有挑战性的。在本文中，我们提出了一种控制方案，该方案将分布式能源资源聚合与变电站变压器的有载调压分接头进行协调，根据它们所连接的变电站要求其贡献功率，并依赖轻量级通信。我们的模拟表明，所提出的控制能够成功协调分布式能源资源和有载调压分接头，以增强长期电压稳定性。
英文摘要
Voltage stability can be endangered in transmission networks that operate under high strain and exhibit a large separation between generators and loads. During emergencies associated to voltage instability, one promising supporting countermeasure is to control large populations of Distributed Energy Resources (DERs) connected to medium- and low-voltage networks, so that they locally reduce the net load by modifying their power generation or consumption. However, it is challenging to achieve this control while anticipating interactions with legacy voltage regulators, coordinating efforts across substations, and exchanging small amounts of information with DERs. In this paper, we propose a control scheme that coordinates DER aggregations with the load tap changers of substation transformers, asks them to contribute power depending on the substation they are connected to, and relies on lightweight communication. Our simulations show that the proposed control can successfully coordinate DERs and load tap changers to enhance long-term voltage stability.
