摘要

我们考虑的问题是分散控制分布式能源资源提供的无功功率，以支持配电网的电压。我们假设电网的无功矩阵是未知的，并且可能随时间变化。我们提出了一种分散自适应控制器，其中每个逆变器的无功功率都是通过潜在的异质下垂曲线来设置的，并分析了由此产生的系统的稳定性和稳态误差。通过使用改进版 IEEE 13 总线和 8500 节点测试系统进行仿真，验证了控制器的有效性。

Decentralized Reactive Power Control in Distribution Grids With Unknown Reactance Matrix

We consider the problem of decentralized control of reactive power provided by distributed energy resources for voltage support in the distribution grid. We assume that the reactance matrix of the grid is unknown and potentially time-varying. We present a decentralized adaptive controller in which the reactive power at each inverter is set using a potentially heterogeneous droop curve and analyze the stability and the steady-state error of the resulting system. The effectiveness of the controller is validated in simulations using a modified version of the IEEE 13-bus and a 8500-node test system.
