论文摘要
光伏（PV）智能逆变器中的VAR和伏特功能提供了确保系统电压幅度和功率因数保持在可接受的极限范围内的机制。但是，这些控制功能可能会变得不稳定，如果在网络攻击过程中未适当配置或恶性变化时，会引入系统电压的振荡。如果VAR-VAR和伏特控制功能在分布网格中的一部分PV智能逆变器中的功能是不稳定的，则提议的适应方案利用其余且稳定的PV智能逆变器和其他分布式能源来减轻不稳定性的影响。适应机制完全分散，无模型，无通信，几乎不需要外部配置。我们提供了自适应控制方法的推导，并验证了IEEE 37和8500节点测试馈线的实验中的算法。
Volt-VAR and Volt-Watt functionality in photovoltaic (PV) smart inverters provide mechanisms to ensure system voltage magnitudes and power factors remain within acceptable limits. However, these control functions can become unstable, introducing oscillations in system voltages when not appropriately configured or maliciously altered during a cyberattack. In the event that Volt-VAR and Volt-Watt control functions in a portion of PV smart inverters in a distribution grid are unstable, the proposed adaptation scheme utilizes the remaining and stably-behaving PV smart inverters and other Distributed Energy Resources to mitigate the effect of the instability. The adaptation mechanism is entirely decentralized, model-free, communication-free, and requires virtually no external configuration. We provide a derivation of the adaptive control approach and validate the algorithm in experiments on the IEEE 37 and 8500 node test feeders.
