Abstract: 
The economic dispatch problem of a smart grid under vicious denial of service (DoS) is the main focus of this paper. Taking the actual situation of power generation as a starting point, a new distributed optimization model is established which takes the environmental pollution penalty into account. For saving the limited bandwidth, a novel distributed event-triggered scheme is proposed to keep the resilience and economy of a class of cyber-power systems when the communication network is subject to malicious DoS attack. Then an improved multi-agent consensus protocol based on the gradient descent idea is designed to solve the minimization problem, and the prerequisites to minimize the system power generation cost are analyzed from the aspects of optimality and stability. Finally, the theoretical results are verified through a single-area 10-generator unit simulation.

摘要:本文研究焦点是恶意拒绝服务(DoS)攻击下智能电网经济调度问题。以发电实际情况为出发点,建立考虑环境污染代价的新型分布式优化模型。为节省有限的带宽资源,提出一种新的分布式事件触发方案,以在通信网络遭受恶意DoS攻击时保持信息物理电网系统的弹性和经济性。然后,根据梯度下降算法设计一种多智能体一致性协议解决最小化问题,并从最优性和稳定性角度分析系统发电成本最小化的前提。最后,通过单区域10发电机组模拟实验验证了理论结果。
