摘要:

智能电网的网络安全已成为发展可靠的现代电力和能源系统的关键问题之一。本文介绍了一种非平稳的对抗成本与变化约束的智能电网,使我们能够在一个相对实际的情况下,研究最佳的智能电网保护免受网络攻击的问题。特别地,构造了一个具有对抗成本的贝叶斯多节点强盗(MNB)模型,并定义了一个新的后悔函数。提出了一种求解该问题的算法-通过算例验证了该算法在实际智能电网中的适用性和性能。

英文摘要:

The cybersecurity of smart grids has become one of key problems in developing reliable modern power and energy systems. This paper introduces a non-stationary adversarial cost with a variation constraint for smart grids and enables us to investigate the problem of optimal smart grid protection against cyber attacks in a relatively practical scenario. In particular, a Bayesian multi-node bandit (MNB) model with adversarial costs is constructed and a new regret function is defined for this model. An algorithm called Thompson-Hedge algorithm is presented to solve the problem and the superior performance of the proposed algorithm is proven in terms of the convergence rate of the regret function. The applicability of the algorithm to real smart grid scenarios is verified and the performance of the algorithm is also demonstrated by numerical examples.
