Power systems security analysis

2006 IEEE Power Engineering Society General Meeting, 2006
Due to the deregulation consequences (economical imperatives and technical difficulties), the electric power systems operate nowadays close to the security limits. In order to protect the grid against severe contingencies and to increase the security margins, the transmission systems operators have to take special measures.

Power system security assessment

IEEE Power and Energy Magazine, 2004
Security refers to the degree of risk in a power system's ability to survive imminent disturbances (contingencies) without interruption to customer service. It relates to robustness of the system to imminent disturbances and, hence, depends on the system operating condition as well as the contingent probability of disturbances.

VAR Planning for Power System Security

IEEE Power Engineering Review, 1989
A method is presented for identifying a dispersed reactive power (VAr) supply that can enhance power systems' pre- and post-contingency voltage security, subject to technical and economic constraints. The problem is formulated in two stages. The first stage involves a nonlinear optimization problem which minimizes the amount of reactive supply.
