Power system security and reliability have become challenging issues in the present restructured scenario. Nowadays, power systems are forced to operate under stressed operating conditions closer to their security limits due to increased loading and large interconnections. Under such fragile conditions, any small disturbance could endanger system security particularly in contingency conditions ...

Power system security, congestion management, power quality and power regulations are major concepts that draw the attention of power researchers in deregulated surroundings. Security assessment is an issue of at most grandness under ‘open market access system’ to render authentic and procure electricity to its customers. The goal of Security assessment is to provide selective information to th...

concerns related to climate change and security of energy supply is pushing various countries to make strategic energy planning decisions. in this regard, energy system modelling is an appropriate method to find out the utilization of current declining non-renewable energy resources and other possible scenarios. consequently, it is available to consider various aspects of energy system decision...

in emerging electric power systems, increased transactions often lead to the situations where the system no longer remains in secure operating region. the flexible ac transmission system (facts) controllers can play an important role in the power system security enhancement. however, due to high capital investment, it is necessary to locate these controllers optimally in the power system. facts...

Power system real time security assessment is one of the fundamental modules of the electricity markets. Typically, when a contingency occurs, it is required that security assessment and enhancement module shall be ready for action within about 20 min time to meet the real time requirement. The recent California black out again highlighted the importance of system security. This paper proposed ...

In this paper, a probabilistic neural network (PNN) based classifier is used to judge the static security of the power system. The proposed classifier classifies the security of the power system based on the voltage profile of each bus in reference to changes in the generation and load profile in the system. The probabilistic neural network is used and compared with the radial basis function ne...
