So it is an important task for ISO to maintain congestion free power system. In this paper generator rescheduling technique has been adopted with incorporation of wind farm in the system. Present work is three folded. Firstly location of wind farm is selected based upon power transfer distribution factor (PTDF). Secondly generator sensitivity factor (GSF) has been determined to reduce number of participating generator in congestion management. Thirdly selected generators have been rescheduled using Artificial Bee Colony (ABC) optimization techniques to mitigate transmission congestion. The proposed method is applied on IEEE 39 bus New England test system.","PeriodicalId":313185,"journal":{"name":"2013 Annual IEEE India Conference (INDICON)","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132049707","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Analysis of land feature dynamics would reveal the changes that occur due to human induced activities or natural phenomenon. This plays a major role in providing up-to-date information of the natural resources. Data acquired remotely through space-borne sensors at regular intervals in visible and microwave bands aid in spatial mapping of the land features. Data acquired in visible and IR (Infrared) bands have been used for land use and land cover analysis. However, these data fails when there are cloud cover due to non-selective scattering. In this context, RADAR remote sensing would be useful as it provide information during all seasons due to long penetration properties. In present study, RADARSAT-2 single polarized HH (i.e., Horizontal to Horizontal with C-band) has been used to derive land features with spatial extent. Radar data interpretation and analysis is considered challenging and have both advantages and disadvantages in land use feature extraction. This study assess the performance of classification algorithms (Gaussian Maximum likelihood classifier (GMLC), Neural network classifier, Decision tree classifier (DTC), Contextual classification using sequential maximum a posteriori (SMAP) estimation for feature extraction using multi-temporal single polarized RADARSAT data, texture extracted data and fused data (optical sensor -LANDSAT ETM+ with SAR data).

The purpose of the present work is to analyze the network performance with optimally sized Wind Turbine Generator System (WTGS) based DG units with random wind velocity variations. In the present work, three DG units are integrated in the Radial Distribution System (RDS) simultaneously. The grid integration points of DG units are determined using Maximum Penetration Ranking. The sizing of DG is carried out by optimizing a multi-objective function formulated using Goal Attainment Method. The solution of the multi-objective function is obtained employing Particle Swarm Optimization (PSO) technique. The network performance is evaluated by varying the stator connection of WTGS based on wind speed and also by varying the network parameters.

The scalar control is an easy to implement but it gives poor dynamic response. In addition to the scalar control the space vector pulse width modulation (SVPWM) is used for effective utilization of the dc-link voltage i.e. SVPWM is having the good voltage regulation and reduces the considerable harmonics in voltage as well as current of the inverter. The dynamic response of the induction motor is improved using direct torque control with SVPWM technique. The performance of induction motor with scalar control and direct torque control is simulated in the Matlab environment and compared their response under similar operating conditions. The dynamic performance, the speed regulation, THD in the current, and the torque distortion of induction motor are effectively improved with direct torque control (i.e. lesser transient time) even while applying the load in comparison to scalar control.","PeriodicalId":313185,"journal":{"name":"2013 Annual IEEE India Conference (INDICON)","volume":"126 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123232019","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The existing schemes are based on context transfer for fast hand-off, but needs to reduce the latency of hand-off for VANETs. Fast hand-off in vehicle scans only the selected AP at any instance of time depending upon the association pattern. The Fast Hand-off Algorithm using AP Graph with Multiple Vehicles for VANET improves the re-association latency and context transfer process must be separated from reassociation process. From experimental and simulation results, we find that the use of AP graphs reduces the handoff latency due to re-association process and that the effectiveness of the approach improves dramatically as user mobility increases. The context transfer process for proactive fashion is used for fast handoff and reducing the context transfer latency of handoffs. The Inter-Access Point Protocol (IAPP) protocol is called the context transfer protocol.","PeriodicalId":313185,"journal":{"name":"2013 Annual IEEE India Conference (INDICON)","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123390019","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Nowadays, the semiconductor industry is unable to follow the Moore's law as miniaturization of CMOS is nearing its limit due to the enormous increase in leakage currents. Hence, STT-MTJ with better features has the capability of replacing conventional CMOS transistors in the future. In this work, we design a reconfigurable full adder using the majority logic, which can act as an ALU. For this, we design a sum generator and a carry generator using MTJs and CMOSFETs. CMOS transistors switch the mode of operation of the sum generator and the carry generator from writing phase to reading phase and vice versa. During writing phase, input current pulses pass through MTJs which change MTJs' magnetization direction. During the reading phase, based on MTJs' magnetization direction, the output logic is interpreted. We show that, the full adder can be reconfigured to perform various arithmetic and logical operations. Our proposed reconfigurable spintronic ALU, can perform arithmetic operations like addition and subtraction, and various logical operations like AND, OR, NAND, NOR, NOT, XOR and XNOR using which a non-volatile digital system can be realised.","PeriodicalId":313185,"journal":{"name":"2013 Annual IEEE India Conference (INDICON)","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126805162","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In such systems, unsupervised adaptation has to performed with a very small amount of adaptation data. Furthermore, in such tasks, the computational complexity involved should be as low as possible to keep the system latency in check. To address both these issues, a model interpolation based fast adaptation procedure, employing speaker cluster models as bases, is presented in this work. It is observed that the acoustic clustering of the training speakers to derive the bases greatly reduces the complexity in comparison to the techniques which employ speaker adapted models as bases. Apart from this, a KSVD based acoustic clustering scheme is also proposed. Acoustic clustering in supervised as well unsupervised mode is explored in this work. The proposed on-line adaptation procedure employing the KSVD clustering, is found to result in a relative improvement of 6% in WER on an LVCSR task.","PeriodicalId":313185,"journal":{"name":"2013 Annual IEEE India Conference (INDICON)","volume":"60 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121018620","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
