Smart grid security is crucial to maintain stable and reliable power system operation during the contingency situation due to the failure of any critical power system component. Ensuring a ‘secured smart grid’ involves with a less possibility of power grid collapse or equipment malfunction. Due to lack of the proper ‘security measures’, a major blackout may occur which can even lead to a cascad...

Weak inertia characteristics of power systems with high penetrations renewables have become a prominent problem for frequency security. To solve this problem, convolutional neural network (CNN)-based deep learning approach is applied to realize rapid security assessment (FSA). First, the time series feature autonomously mined from wide-area measurement data serve as input data. By doing so, com...

1639 Venkateswara and Kumar Firefly Algorithm based Optimal Power Flow with Static VAR Compensator for Improvement of Power System Security under Network Contingency  Abstract— At present owing to the increase in power demand power system have become more complex and heavily loaded, and are subjected to unstable or insecure operations. In order to provide a secure operation of the power system...
