在本文中，我们从跨层的角度设计了一个安全、稳健和有弹性的网络物理风能系统（WES）。我们为大型风电场建立了一个系统框架，其中包括网络和物理组件。对于网络层，我们使用博弈论模型来捕获网络防御者和网络攻击者的策略行为，并计算其混合策略纳什均衡。对于物理层，我们使用马尔可夫跳跃线性系统模型设计了一个鲁棒且有弹性的开关控制器。由于网络系统和物理系统之间的相互依赖，它们的性能是耦合的，需要进行整体设计。为了应对这一挑战，我们提出了一种迭代算法来研究平衡设计下的系统性能，该设计同时考虑了网络层和物理层。提供案例研究来说明网络物理 WES 的相互依赖的设计原则。
In this paper, we design a secure, robust and resilient cyber-physical wind energy system (WES) from a cross-layer perspective. We establish a system-of-systems framework for the large-scale wind farm which includes the cyber and physical components. For the cyber layer, we use a game-theoretic model to capture the strategic behaviors of the network defender and the cyber attacker, and compute its mixed strategy Nash equilibria. For the physical layer, we design a robust and resilient switching controller using a Markov jump linear system model. Due to the interdependence between the cyber and physical systems, their performances are coupled and need to be designed in a holistic manner. To address this challenge, we propose an iterative algorithm to study the system-of-systems performance under the equilibrium design which jointly takes the cyber and physical layers into account. Case studies are provided to illustrate the interdependent design principles of cyber-physical WES.
