Abstract: The opportunistic relaying scheme with the selection of antenna at source is the best alternative to get many of the benefits of MIMO [1]. In such a scheme, the best relay as well as best antennas at source can be selected for communication. Here, we will introduce the opportunistic amplify and forward relaying with direct link using antennas selection at source only. Under assumption of Rayleigh fading channel, in this proposed scheme the exact BER (bit error rate) performance will be analyzed and observed that the increasing antennas is a better option as compared to relays

Abstract: With an increase in power transfer, transient stability is increasingly becoming important for secure operation. With the advent of FACTS devices, the problem of transient stability is being addressed and efforts are under way to utilize the systems to their full capacity. The focus of this work is a neural network predictive controller for a versatile FACTs device, Unified Power Flow Controller, which can be utilized to improve the transient stability performance of the system. A single machine infinite bus system subjected to a 3-phase short circuit fault is used to demonstrate the superior damping performance of the proposed controller in comparison to the conventional PI controller
