Securing Power System State Estimation
2016 IEEE Trustcom/BigDataSE/ISPA, 2016In power system, state estimation is the basis of protecting and controlling the power grid. However, attackers can interfere the normal state estimating processes by strategically altering certain measurements through false data injection (FDI) attack. To address this problem, a typical solution is deploying a large amount of phasor measurement units (

VAR Planning for Power System Security
IEEE Power Engineering Review, 1989A 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.

A testbed for power system security evaluation
International Journal of Information and Computer Security, 2009This paper describes a project that integrates real devices used in the electric power grid with a simulation of electrical power generation and distribution, and a computer/communication simulator. The testbed is designed to evaluate the cyber-security of power grid control systems.

Impact of Security on Power Systems Operation
Proceedings of the IEEE, 2005This paper reviews the status of security analyses in vertically integrated utilities and discusses the impact of system security on the operation and the planning of restructured power systems. The paper is focused on the static security rather than the dynamic security of power systems. The paper also discusses assumptions, functions, and calculation

Power and Permission in Security Systems
2000It is a standard feature of all organisations that designated agents, usually when acting in specific roles, are empowered by the organisation to create specified kinds of states of affairs – as when, for instance, a priest declares a couple as married and thereby makes it so in the eye of the church, or when a head of department assigns one of his ...

Reflections on security [power systems]
IEEE Power and Energy Magazine, 2003The North American Electric Reliability Council (NERC) has been responsible for the reliability of the interconnected grid, of which safety and security are essential ingredients, since 1968. NERC has undertaken several key initiatives (many of which began well before September 11) to focus attention on security matters and to encourage electric power ...

Security and Optimization in Power Systems
IFAC Proceedings Volumes, 1988Abstract Security and optimization are becoming the main issues of power system control which is oriented according to states. The state concept is used here to characterize the state-of-the-art but also to discuss the frontiers and the expected development. Optimization will expand into more detailed applications of security.

Power Engineering Journal, 2002
Incidents on the electricity transmission system have a low probability but a high impact. The author describes how all phenomena that have this characteristic are difficult to analyse. When a major problem has not happened for a long time, there is a natural tendency to wonder if the security measures are not too strict.

Power systems security analysis
2006 IEEE Power Engineering Society General Meeting, 2006Due 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.

Secure and Stateful Power Transitions in Embedded Systems
Journal of Hardware and Systems Security, 2020Power loss occurs in devices with a transient power supply, and it leads to the loss of volatile state information of the device. To protect the state, the device stores it as a checkpoint in non-volatile memory. The checkpoints are used to restore the device to the most recent stored state upon power-up.
