1 Mitiation Of Voltage Sag Using Dynamic Voltage Restorer (DVR) 1.Andra Nagarjuna,2.V.Srinivasa Rao

Various factors that affect the power quality are voltage unbalance, presence of harmonics, interruptions, the occurrence of faults, and the presence of voltage sag and voltage swell. Out of all the power quality issues, the presence of voltage sags is the critical problem. To address the issues of power quality, special devices are available, which are called flexible alternating current transmission system (FACT) devices.In this paper , various power quality issues are presented. Among all, the occurrence of voltage sag is studied and analyzed. The control circuit to mitigate the voltage sag issues is modeled and simulated. The dynamic voltage restore is used to compensate for the voltages that fall out of the limits. The entire analysis is carried out in MATLAB/SIMULINK. The detailed model for the dynamic voltage restorer is also presented. The circuit topology, control logic, various subsystems, and generation of the voltage sag are important aspects of this paper.

2 Design Of Hybrid Energy Storage Systems In Dc Microgrid Applications 1.Kancherla Satyapriya,2.T.lingaiah

Due to smooth integration with renewable power resources in addition to the proliferation of dc-well suited loads, dc microgrids are gaining recognition. Because of the excessive penetration of renewable strength sources in dc microgrids, those microgrids are relatively vulnerable to fluctuations in the electricity era. It is harmful, so extreme voltage balance is considered. To absorb these fluctuations within, a battery-primarily based electricity storage gadget and hybrid energy storage machine (HESS), including a battery and supercapacitor (SC), are proposed. The specific traits of the cell and supercapacitors cause them to a super aggregate for HESS applications. The HESS is interfaced with dc microgrid using a double-enter bidirectional converter. This bidirectional converter gives decoupled manipulate of battery and supercapacitor power. This thesis provides a converter modeling technique for the double-input bidirectional converter. A controller was designed based totally in this for voltage law utility for a dc microgrid. The operation of the converter made it feasible to use the equal controller for each HESS charging and discharging process, consequently making it a unified controller. The designed controller was also capable of reject disturbances from the source facet in addition to load facet even as keeping the voltage balance of the dc microgrid. Operation of the converters and overall performance of the designed controller in voltage stability was tested with simulation consequences for each battery by myself garage gadget and hybrid power storage systems.

3 Power Flow Control In VSC Based HVDC System 1.Potla Srinu Mahesh,2.M Bhavya Sri

Due to the increasing demand for electric power, various technologies are coming up to transfer the bulk amount of power. The most prominent technologies used in  electric power transmission are extra high voltage alternating current (EHVAC) transmission and the high voltage direct current (HVDC) transmission. The evolution of power transformer made extra high voltage alternating current transmission to use in bulk power transmission. In contrast, the high voltage direct current transmission technology is evolved due to the development of power electronics technology. Compared to EHVAC transmission, high voltage direct current transmission is playing a significant role in power transmission due to the many advantages at high voltages and also for long distances.In this report, the modeling and the analysis of the VSC-HVDC system is carried out to evaluate the performance in electric power transmission. The waveforms for sending end AC and the receiving end DC are shown. The entire analysis is carried out in MATLAB / SIMULINK. The results obtained in this paper are useful in understanding the performance of the VSC HVDC system and can apply to all the systems.

4 Intercloud Privacy Preserving Using Trust Evaluation Protocol 1.Shaik Irfan Basha,2.D.Rammohanreddy

Inter cloud strives to facilitate resource sharing between clouds. For Inter cloud orientation, a framework of analysis accepted as valid between draws and users is required. To be considered for evaluation, standard protocols typically support a central design that specializes in one-way courtship. For Inter cloud, the environment can be very dynamic and distributed, and relationships will be one-way or two-way (that is, clouds offer presentations for each). This document provides acceptance that is cashed, according to Inter cloud's Privacy Security Examination Protocol. New contributions and recent options are summarized below. First of all, comments are protected by ambiguous writing with a verifiable confidential exchange. Second, to understand the dynamic nature of Inter cloud, the evaluation can be agreed within a fully paid manner and be useful even once several events have stopped connecting to the internet. Third, to properly facilitate personal acceptance with analysis, Associate in Nursing's innovative mechanism is used to save comments, so they are flexibly processed and protect comments privacy. The protocol is proven to support an adequate security version. Simulations are performed to demonstrate the effectiveness of the protocol. The results show that even once half of the cloud becomes malicious or offline, the protocol will direct a robust trust analysis with privacy security by defining appropriate operational parameters.

5 Effect Of Pattern Loading On Seismic Behaviour Of Structures By Considering Infilled Effect 1.N.Prasanth Kumar,2.Budda Beeraiah

The accurate estimation of design actions on the structure is very important in structural design as it significantly affects the final design and objectives. Any error in the estimation of design actions may lead to wrong results of structural analysis on the structure and lead to the unrealistic sizing of its structural members or even collapse of the structure. Therefore it is important to account for the most adverse effects of live loads on the structure. The consideration of pattern loading depends on the ratio of dead to live load and the type of structural member. These days most of the engineers are not considering the different live load patterns to get the adverse effect of the structure. Considering the live load to all the slab panels may not appropriate to estimate the design parameters. In this context, an attempt is required to see the effect of pattern live load on the structure under seismic loads. The effect of pattern load may be different from bare frame structure and also infill structures. For the present work a regular symmetrical building will be chosen and the structure is loaded with different pattern live loading is analyzed for seismic load case with and without infill walls. Different dead loads to live load ratios are also considered as a parameter.
