Assessment of Sabotage Factors in the Electricity Market Considering System Reliability

Recently, smart grids have emerged as a new solution for the next generation of power systems. Cyber-attacks can take place against these. System performance may be reduced as a result of this sabotage. The purpose of this research is to the impact of a vandalism model with possible cyber-attacks on the electricity market, which is to make the generation unit or transmission line unavailable. The operator intends to have the minimum cost before and after the system attack from an economic viewpoint. For this purpose, several scenarios have been implemented in the system. The CPLEX solver is used to solve the proposed Mixed Integer Linear Programming (MILP) model. The obtained results show that the costs increased after the attack due to considering combined attacks on the network. Also, the worst-case scenario that has led to the change of output power for peak hours is identified.
