Fuzzy‐based frequency security evaluation of wind‐integrated power systems

Contributions to Security of Electric Power Systems

Electricity supply is a fundamental need of a modern society. A crucial property of electricity supply reliability, is achieved by keeping a power system in a secure state most of the time. A secure state means, that the risk of a disturbance to spread further and endanger the system integrity, resulting into supply interruptions, is minimal. Keeping a power system secure is a very challenging ...

A New Class of Decentralized Interaction Estimators for Load Frequency Control in Multi-Area Power Systems

Load Frequency Control (LFC) has received considerable attention during last decades. This paper proposes a new method for designing decentralized interaction estimators for interconnected large-scale systems and utilizes it to multi-area power systems. For each local area, a local estimator is designed to estimate the interactions of this area using only the local output measurements. In fact,...

A testbed for power system security evaluation

This 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. Through a combination of simulation and emulation, the testbed seamlessly integrates virtual and real components...

Security Aspects in Radio Frequency Identification Systems

Radio frequency identification technology is becoming ubiquitous, and as an unfortunate side effect, more and more authentication solutions come with more security issues. In former contributions, the authors introduced a solely hash-based secure authentication algorithm that is capable of providing protection against most of the well-known attacks and performs exceptionally well even in very l...
