Transmission Loss allocation with Optimal Power Flow using Gravitational Search Algorithm
N. V. SUBBA RAO, G. KESAVA RAO, S. SIVANAGARAJU
DOI: 10.17148/IJIREEICE.2014.21101
Abstract: In deregulated power systems, the transmission loss allocation plays a key role in planning and designing of the power system. In practice, these losses should be allocated to both generators and loads depending on the amount of contribution in the total power system losses. In this paper, a new methodology to optimally allocate the transmission losses to either generators or loads based on the power flow tracing methodology is presented. In this methodology, trace usage coefficients are formulated to allocate transmission losses. In real time, system operator tries to minimize the transmission losses to increase the security of the system. In this paper, for the sack of analysis, the formulated OPF problem with transmission losses as objective is solved while satisfying system constraints using gravitational search algorithm. The minimized transmission losses are then allocated to either generators or loads. The proposed methodology is tested on standard IEEE-30 bus and real time Indian-24 bus test systems with supporting numerical results.

DOI: 10.17148/IJIREEICE.2014.21102
Abstract: A new architecture, namely, Multiplier-and accumulator (MAC) based Radix-4 Booth Multiplication Algorithm for high-speed arithmetic logics have been proposed and implemented on Xilinx FPGA device. By combining multiplication with accumulation and devising a hybrid type adder the performance was improved. The modified booth encoder will reduce the number of partial products generated by a factor of 2. Fast multipliers are essential parts of digital signal processing systems. The speed of multiply operation is of great importance in digital signal processing as well as in the general purpose processors. The number to be added is the multiplicand, the number of times that it is added is the multiplier, and the result is the product. Each step of addition generates a partial product.

Y.N.VIJAYAKUMAR, DR. SIVANAGARAJU
DOI: 10.17148/IJIREEICE.2014.21104
Abstract: The interline power flow controller (IPFC) is one of the latest generation flexible AC transmission systems (FACTS) controller used to control power flows of multiple transmission lines. In recent years, power demand has increased substantially while the expansion of power generation and transmission. It has been severely limited due to limited resources and environmental limitations. Flexible AC Transmission Systems (FACTS) controllers have been mainly used for solving various power system steady state control problems. Interline Power Flow Controller is a versatile device can be used to control power flows of a multi-line system or sub-networks An Interline Power Flow Controller (IPFC) is a converter based FACTS controller for series compensation with capability of controlling power flow among multi-lines within the same corridor of the transmission line. It consists of two or more Voltage Source Converters (VSCs) with a common dc-link. Real power can be transferred via the common dc-link between the VSCs and each VSC is capable of exchanging reactive power with its own transmission system. In this paper, a control scheme of an IPFC system with two VSCs to compensate the impedances of two similarly dimensioned parallel transmission lines is presented. A Mathematical model of the IPFC is presented and the model is used to investigate the flexibility of power flow control, in the presence of operating constraints of the IPFC. In this paper, the application of Interline Power Flow Controller (IPFC) in damping of low frequency oscillations is investigated. The potential of various IPFC control signals upon the power system oscillation stability is investigated under various loading conditions.

DOI: 10.17148/IJIREEICE.2014.21107
Abstract: Wireless sensor networks represent a key technology enabler for enhanced health care and assisted living systems. Recent standardization efforts to ensure compatibility among sensor network systems have produced the IEEE 802.15.4 standard, which specifies the MAC and physical layer behaviour. Energy and network life time are two critical factors for WSN performance. IEEE 802.15.4 is a standard used for low data rate Wireless Personal Area Networks (WPANs). Medium Access Control layer (MAC) of IEEE 802.15.4 plays an important role in the performance of Wireless Sensor Network (WSN). The unique feature of this MAC layer is the superframe structure, which allows devices to access channels in a Contention Access Period (CAP) or Collision Free Period (CFP) and use beacon based synchronization mechanism. In this paper, we propose a cross-layer framework to prolong the network lifetime, to improve the energy and to lower the latency of WSNs based on the IEEE 802.15.4/ZigBee standards. To cover all the scenarios, we have considered hierarchical topology and peer to peer beacon enabled network. The performance metrics are evaluated using simulation results.

Abstract: In recent trends, multi-threshold CMOS technology is advancing to enhance performance of any digital circuits. By use of this technology any digital circuit makes use of both low threshold voltage (VDDL) and high threshold voltage (VDDH) MOSFETs. Propagation delay time of a circuit is reduced by using VDDL and consumption of power is reduced by using VDDH. One of the best techniques to reduce the power consumption is scaling the supply voltage VDD. In order to maintain the generational speed enhancement, the device threshold voltage VTH must also scale down with VDD. This paper proposes a low-power circuit with MTCMOS technology, simulation results shows that power consumption is reduced approximately by61.7%.

Abstract: The output of the solar photovoltaic (PV) arrays is not constant throughout the day. It varies with time. Output change with the climatic condition, it varies in summer winter and rainy season. So we cannot get the maximum output all the time. This paper discuss the factor that effect solar PV performance in different environment condition and location of PV module. These factors may be orientation of the PV module, tracking the sun, temperature of PV module, incidence/tilt angle of the PV panel, shading of the panel, mounting rooftop material, mounting height, solar irradiance, type of PV module, and dust on module. Above said are some important factor that significantly affects the performance of solar photovoltaic cells. So need to be discussed.

DOI: 10.17148/IJIREEICE.2014.21112
Abstract: Efficient water management is the only way to avoid frazzle of freshwater. Agriculture utilizes most of the fresh water; since the atmospheric parameters vary from place to place in large farm field, it makes very difficult to maintain the uniformity in all the places of farm field manually. So a combined function of wireless sensor network (WSN) and embedded system is used to control the irrigation.The soil moisture and temperature sensors are incorporated in root zones of the plants. ZIGBEE radio modem transmits the information to master microcontroller for processing. The microcontroller is programmed with threshold values of soil moisture and temperature sensors. Automatic irrigation starts when the processed data of the microcontroller drops below the threshold value. The strain sensor is used to indicate the motor theft. A GSM module is embedded to provide the remote control of data inspection and irrigation scheduling.

Abstract: Fingerprint verification is one of the most reliable personal identification methods. It plays a very important role in forensic and civilian applications. In this paper we propose a simple and effective approach for fingerprint liveness detection based on the wavelet analysis of the finger tip surface texture. In present situation, manual fingerprint verification is so tedious, time-consuming, expensive and incapable of meeting today’s increasing performance requirements. Wavelet transform which has wide range of applications such as image compression, denoising noisy data, texture classification, etc., is used for fingerprint verification. Experimental results show that our method can successfully differentiate live finger tips from fake finger tips made of most commonly used material in fingerprint spoofing.
