چکیده
SCADA (Supervisory Control and Data Acquisition) networks of electric power transmission and distribution control centers that were isolated are now connecting to corporate networks, to vendors networks, and even with the Internet in order to increase productivity in a global and open electricity market. This model, Automation Technology (AT) networks connected with Information Technology (IT) networks introduces new security threats and vulnerabilities. This paper presents some considerations about the security aspects of this computer network configuration.

LPKP: location-based probabilistic key pre-distribution scheme for large-scale wireless sensor networks using graph coloring
Communication security of wireless sensor networks is achieved using cryptographic keys assigned to the nodes. Due to resource constraints in such networks, random key pre-distribution schemes are of high interest. Although in most of these schemes no location information is considered, there are scenarios that location information can be obtained by nodes after their deployment. In this paper,...
متن کاملUnder Frequency Load shedding Algorithm in Smart Islanded Networks Using Loads Frequency Index
This paper presents an optimal method of frequency load shedding (UFLS) based on the rate of change of frequency of load (ROCOFL) in islanded distribution networks (DN). The proposed method minimizes the average amount of penalties paid by the independent operator of the network by utilizing the relevant cost function. The function of islanded distribution network occurs after an error in the s...
متن کاملFast Transient Hybrid Neuro Fuzzy Controller for STATCOM During Unbalanced Voltage Sags
A static synchronous compensator (STATCOM) is generally used to regulate voltage and improve transient stability in transmission and distribution networks. This is achieved by controlling reactive power exchange between STATCOM and the grid. Unbalanced sags are the most common type of voltage sags in distribution networks. A static synchronous compensator (STATCOM) is generally used to maintain...
