A Game Framework to Confront Targeted Physical Attacks Considering Optimal Placement of Energy Storage

Abstract

In this paper, a game framework for defending the power system against intelligent physical attacks is modeled by investigating the impacts of Energy Storages (ESs). For this modeling, Optimal Placement of Energy Storage (OPES) with regard to two main cases is investigated. In the first case, it is assumed that just one transmission lines are attacked. This case is equal to making the power system N-1 secure using OPES. In the second case, it is assumed that two transmission line are attacked. Therefore, this case is equal to making the power system N-2 secure using OPES. Moreover, two proposed Algorithms are implemented for limited budget allocation to the power system protection and recovery. A five-bus system as a common case study system is considered for evaluation of the presented model. The obtained results justify the effectiveness of considering OPES for defending the power system against targeted physical attacks.
