论文摘要
通过通信网络运行的同步发电机和能源存储系统的集成为电网带来了新的挑战和脆弱性，在该电网中，网络攻击可以损坏传感器测量或控制输入和中断功能，例如频率调节。本文提出了一种防御方法，以设计对每个一代和存储单元施加的弹性操作约束，以防止任何攻击顺序使系统的频率驱动到不安全条件。通过使用可触及的功率系统集合集的椭圆形近似，可以找到弹性的操作约束，从而导致线性矩阵不平等的凸优化问题。具有同步生成和能量存储的单面积电力系统的数值结果演示了弹性约束如何为影响频率测量或控制器设定点的任何类型的攻击提供安全保证。
The integration of synchronous generators and energy storage systems operated through communication networks introduces new challenges and vulnerabilities to the electric grid, where cyber attacks can corrupt sensor measurements or control inputs and interrupt functions such as frequency regulation. This paper proposes a defense methodology for the design of resilient operating constraints imposed on each generation and storage unit in order to prevent any attack sequence from driving the system's frequency to unsafe conditions. The resilient operating constraints are found by using ellipsoidal approximations of the reachable set of the power system, leading to a convex optimization problem with linear matrix inequalities. Numerical results in a single-area power system with synchronous generation and energy storage demonstrate how the resilient constraints provide security guarantees against any type of attack affecting frequency measurements or controller setpoints.
