双层电网的同步控制

Control of Synchronization in two-layer power grids

Carl H. Totz, Simona Olmi, Eckehard Schöll

摘要:

在这项工作中,我们建议在一个两层网络的动态电网建模,并使用意大利的高压电网作为一个证明的原则的例子。在我们的模型中的第一层表示由发电机和消费者组成的电网,而第二层表示作为第一层的控制器的动态通信网络。特别地,电网的动态由具有惯性的Kuramoto模型建模,而通信层为每个发电机提供控制信号$P_i$以改善电网内的频率同步。我们提出了通信层拓扑结构的不同实现和计算控制信号的不同方法。然后,我们进行了系统的调查的两层系统对众多不同的现实扰动的情况下,如断开发电机,消费者的需求增加,或发电机随机功率输出。当使用一个控制拓扑结构,允许所有的发电机交换信息,我们发现,一个控制方案,旨在尽量减少相邻节点之间的频率差非常有效,即使对最坏的情况下,最强的扰动。

英文摘要:

In this work we suggest to model the dynamics of power grids in terms of a two-layer network, and use the Italian high voltage power grid as a proof-of-principle example. The first layer in our model represents the power grid consisting of generators and consumers, while the second layer represents a dynamic communication network that serves as a controller of the first layer. In particular, the dynamics of the power grid is modelled by the Kuramoto model with inertia, while the communication layer provides a control signal $P_i$ for each generator to improve frequency synchronization within the power grid. We propose different realizations of the communication layer topology and different ways to calculate the control signal. Then we conduct a systematic survey of the two-layer system against a multitude of different realistic perturbation scenarios, such as disconnecting generators, increasing demand of consumers, or generators with stochastic power output. When using a control topology that allows all generators to exchange information, we find that a control scheme aimed to minimize the frequency difference between adjacent nodes operates very efficiently even against the worst scenarios with the strongest perturbations.
