Ensuring power system security against contingencies
2007 International Conference on Industrial and Information Systems, 2007A power system is secure against a given contingency if it operates within acceptable operating limits before and after the occurrence of the contingency. In practice, it is not possible to secure a power system against all possible contingencies. Therefore, only the most critical contingencies (imminent disturbances) are considered. The paper gives an

Security region analysis of power systems
6th International Conference on Advances in Power System Control, Operation and Management. Proceedings. APSCOM 2003, 2003This paper introduces the concept of extended dynamic security region (EDSR) to characterize the transient stability of power systems. Roughly speaking, if the present state of power system lies in the EDSR, the system maintains stability after experiencing disturbance.

Security issues of power system interconnection
IEEE Power Engineering Society General Meeting, 2005, 2005Voltage stability, transient stability and dynamic stability studies are three approaches to power system security studies. For evaluation of the synchronous interconnection of the African regional power pools interconnection, security issues should be taken care of before any economic analysis is done.

Security Modelling for Power System Reliability Evaluation
IEEE Transactions on Power Systems, 2001This paper presents conceptual development, computation procedure and simulation results of the methodology for modelling security within reliability evaluation of power systems. The proposed approach takes into account activation of protection and automatic controls, local actions of operators, as well as centralized decisions taken by system ...

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 ...

Security evaluation of composite power systems
IEE Proceedings - Generation, Transmission and Distribution, 1995An approach to the security evaluation of a composite power system is proposed which uses probability techniques for quantitative power system reliability analysis. This approach incorporates both steady-state and transient-state considerations in the reliability evaluation of composite power systems.
