在本文中，我们提出了一种分布式电压控制在配电网通过无功补偿。所提出的控制可以以分布式方式操作，其中每个总线根据本地电压测量和与相邻总线的通信做出决策，始终满足无功功率容量约束，将电压幅值驱动到可接受的范围内，并使操作成本最小化。我们还进行了各种数值案例研究，以证明使用非线性潮流模型的控制器的有效性和鲁棒性。
In this paper, we propose a distributed voltage control in power distribution networks through reactive power compensation. The proposed control can operate in a distributed fashion where each bus makes its decision based on local voltage measurements and communication with neighboring buses, always satisfy the reactive power capacity constraint, drive the voltage magnitude into an acceptable range, and minimize an operational cost. We also perform various numerical case studies to demonstrate the effectiveness and robustness of the controller using the nonlinear power flow model.
