In business perspective, it is important as a potential method for copy right protection, proof of ownership broadcast monitoring etc. In academic perspective, it is an interesting research problem. Audio watermarking is the most challenging of all as Human Auditory System is sensitive to even a very small change to the original audio. Other than imperceptibility of the signal, capacity and robustness are important too. Empirical mode decomposition is the latest revolutionary concept in audio watermarking. In this paper we present a robust audio watermarking scheme which ensures imperceptibility, robustness and high payload capacity. To prevent un-authorized third parties from removing the watermark, we make use of Tinkerbell chaotic map to generate random secret keys and watermark is embedded following the keys. Multiple keys are used to ensure efficient distribution of the watermark to prevent cropping attacks and enable watermark correction and synchronization with receiver. The experimental results show that the method is robust against re-sampling, cropping, re-quantization, AWGN attacks.","PeriodicalId":373395,"journal":{"name":"2015 International Conference on Power, Instrumentation, Control and Computing (PICC)","volume":"56 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132030937","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 voltage instability of a power system is mainly caused due to some disturbance occurring at some location, due to which rapid voltage drop occurs. This voltage drop can turn cumulative and finally lead to voltage collapse. In this work the voltage stability analysis is performed on the test system to evaluate the influence of FACTS devices on improving the voltage profile of the system. The optimal location for the installation of the FACTS controllers is obtained using the line stability index Lmn and validated using power flow analysis. A comparative study is conducted to select the best FACTS controller in terms of voltage stability. The WSCC 9-bus system is taken as the test system. Simulations are done in MATLAB/PSAT environment. From the simulation results it has been found that with the optimal implementation of FACTS controllers the voltage stability of the power system was improved and the real power losses in the system was reduced considerably.","PeriodicalId":373395,"journal":{"name":"2015 International Conference on Power, Instrumentation, Control and Computing (PICC)","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130403057","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 order to avoid these blackouts from occurring in the power system, an effective forced islanding scheme with a suitable load shedding scheme can be used. This paper proposes an algorithm that identifies the risk during an outage and forcefully splits the system into predefined islands to prevent the propagation of cascading failures across a transmission network and thereby reducing the possibility of a large-scale blackout. The scheme makes use of DC load flow studies and sensitivity factors, such as Line Outage Distribution Factor (LODF) and Generation Shift Factors (GSF), to calculate the overloads occurring due to the outage. For each outage, the forced islands to be formed are predefined. After splitting the system into islands, the islands are analyzed for stability. If they are found to be unstable, then an under-voltage load shedding scheme is adopted to bring the system back to stability. The proposed work is carried out on a sample 6 bus system using MATLAB program.","PeriodicalId":373395,"journal":{"name":"2015 International Conference on Power, Instrumentation, Control and Computing (PICC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124196580","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}

Moreover, demand response can play a very relevant role in the electrical systems with an intensive use of distributed energy resources. During the effort to accommodate larger shares of renewable energy sources, while maintaining the power balance and ensuring the reliability of the power system, the implementation of demand response mechanisms may provide considerable options to reshape the supply of electrical energy. As demand response levels have decreased after the introduction of competition in the power industry, new approaches are required to take full advantage of demand response opportunities. Here, the study presents a new approach of modeling flexible loads and aims to create further knowledge on the potentials of residential demand response concepts. Modeling of heating systems in a building was done in Matlab/Simulink and analyzed their characteristics in terms of temperature control in order to reach thermal comfort conditions and reduce energy consumption. Large commercial buildings can effectively manage large number responsive loads to provide various demand responsive services, such as peak load reduction.","PeriodicalId":373395,"journal":{"name":"2015 International Conference on Power, Instrumentation, Control and Computing (PICC)","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124792067","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}

This paper proposed the modelling and control of a hybrid solar photo voltaic, wind energy, Diesel-Engine Generator (DEG) and Superconducting Magnetic Energy Storage systems connected to an isolated power system. Due to random variations of wind speed, output power of wind generator fluctuates randomly. Also solar irradiance and temperature variation causes the variation of solar PV output power. This causes fluctuations of power system frequency and thus affects the stability of the system. Due to the intermittent nature of power output from renewable sources, they are integrated along with different energy storage systems. In this project SMES is proposed for minimization of frequency fluctuations of hybrid system. The control scheme of SMES is based on a sinusoidal pulse width-modulation voltage-source converter and a two-quadrant dc-dc chopper using an insulated-gate bipolar transistor. This project analyses the effect of superconducting magnetic energy storage (SMES) to improve the stability of an isolated hybrid system under varying atmospheric conditions. Simulation results indicate that SMES system can contribute to frequency stability when supply demand imbalance occurs.","PeriodicalId":373395,"journal":{"name":"2015 International Conference on Power, Instrumentation, Control and Computing (PICC)","volume":"57 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129404674","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}

Blackouts and cascaded failures are associated with divergent situations in power system. Dynamics of power system pushes the behavior differently under different values of parameters such as increase in load demand at very sensitive bus in power system which may trigger exponential rise in power flows through lines leading to cascaded outages one after other. To study impact of power demand at sensitive bus causing divergent flow over lines, paper proposes chaotic performance index as a watchdog for relative divergent trend of power flow assessment. This will help power system planners to formulate artificial intelligent ways to identify weak chaotic bus and most vulnerable line showing divergent growth of power flow in a given power system network. This paper proposes discrete Largest Lyapunov Exponent based computation for dynamic security assessment. For a particular outage one can identify the most vulnerable transmission line based on algorithm presented in paper. Results and discussions will further support viewpoint of such studies.","PeriodicalId":373395,"journal":{"name":"2015 International Conference on Power, Instrumentation, Control and Computing (PICC)","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115393411","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}
