This paper deals with the analysis and simulation of power system operation with an integrated control viz., under single area and two-area control and it was carried out with the help of MATLAB. The simulation studies will enable an easier understanding of the effect of an actual load change and how the frequency and voltage are maintained by introducing state feedback controller. The paper deals...
With the increased popularity of multimedia applications, there is a great demand for secured data storage and transmission techniques. Information security has traditionally been ensured with data encryption and authentication techniques. Through the years, different generic data encryption standards have been developed. The secrecy of communication is maintained by secret key exchange. In effect...
The paper presents a novel methodology for optimal reactive power pricing in deregulated market. A new method is presented in this paper which aims to supply electricity to the consumer by the supplier in the most economically beneficial way. The objective function is formulated in terms of social welfare function, maximization of which results in the most economical generation and consumption. However...
Cognitive Radio (CR) systems have been proposed to enable flexible use of the frequency spectrum in future generations of wireless networks. These are expected to detect spectrum bands that are not actively used by licensed (primary) users and provide unlicensed (secondary) users access to these bands. In this context it is important for the CR systems to promptly react to changes in the operating...
A new transmission system- Fractional Frequency Transmission System (FFTS) proposed in the literature is a promising alternative to High-Voltage (HV), High Voltage Direct Current (HVDC) and Flexible AC Transmission System (FACTS) technology to increase power transfer capability and to improve voltage profile of the transmission line. In this paper three studies of FFTS are presented to investigate...
In this paper we consider OFDM-based cognitive radios (CR) with linear precoders at the transmitter and minimum mean square error (MMSE) filters at the receiver, and formulate joint spectral allocation and power control subject to specified target signal-to-interference+noise ratio (SINR) as a constrained optimization problem. We discuss necessary and sufficient conditions for the optimal solution...
A new analytical method is proposed which finds reliability, average failure rate and the operation and maintenance cost of wind turbine generator (WTG) using site wind data considering the WTG as a non-repairable system. The failure rate function is developed using WTG failure frequency published by renewable energy information system on internet (REISI), Germany. The presented method works computationally...
