An Electrical Power System Reconfiguration Model Based on Optimal Transmission Switching under Scenarios of Intentional Attacks

Currently, operating electrical power systems (EPS) is a complex task that relies on the experience of operators or strength algorithms developed for autonomous operation. The continuous operation EPS vulnerable to intentional cybernetic and physical attacks. With most significant extension distribution in EPS, transmission lines are exposed potential Before this, entire behavior changes, and, occasions, blackout can even be generated. present investigation focused developing methodology reconfiguring system against attacks, considering topology change through optimal switching (OTS) based DC flows quantifying contingency index, which allows identification weaknesses EPS. was applied IEEE 30−bus system, contingencies were randomly generated, as typical with study successfully identified reconfiguration strategy OTS-DC, mitigating problems such line loadability voltage angle deviation nodes.
