Abstract
  • The majority of power system cascading models assume that system operators will react perfectly and timely to an electrical event. However, as evidenced by several blackouts in the last decades, the inadequate system operators’ situation awareness and response can contribute significantly to the severity of an electrical disturbance. Under these premises, this paper proposes an approach for considering the effect of operators’ response in the cascading modeling of power system blackouts. Particularly, the impact of a delayed reaction by the operator on the number of customers disconnected is investigated. This is achieved by modeling different levels of operators’ response time into the protection device responses (such as relays) and simulating cascades with an open source quasi-steady-state (QSS) simulator. The method is illustrated using the IEEE RTS-96 and Polish Grid networks to quantify the impact of delayed operators’ response and to demonstrate the effectiveness of the proposed methodology. Key Words: Cascading failures, power system reliability, situation awareness, system operators, transmission networks
