Especially, after the industrial revolution in the nineteenth century, first coal and then fuel oil are used as primary energy sources for the needs of modern communities. As it is known, fossil fuels have limited potential, and at the current rate of exploitation they are expected to be depleted within the next centuries. This is one of the reasons why clean, sustainable and environmentally friendly alternative energy resources like wind, solar, etc are currently sought. This paper aims to characterize the power curve of the wind energy production and to estimate the power when a WTG operates between the cut-in wind speed and the rated wind speed. These are done by different methods and their performance is measured using the root mean square error(RMSE). Through the results, it is proved that cluster center estimation method is the best method among all of the other proposed methods.","PeriodicalId":265646,"journal":{"name":"ISGT2011-India","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128299671","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}

Many efforts have been put in determining accurate channel models for the power line, but there is yet not a widely accepted model in the PLC community. This paper presents recent developments on PLC channel modelling and its transfer function. For data communication over any medium, it is necessary to determine the characteristics of the communication channel. In this work, the power line is approximated as a transmission line and the transfer function is derived based on the lumped-element circuit model, using scattering matrix method. The model is capable of determining the line characteristics under different network topologies. The approach allows not only taking into account the cable characteristics, but also the number and length of the branches. This paper strives to broaden the understanding of broadband indoor power line channel.","PeriodicalId":265646,"journal":{"name":"ISGT2011-India","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127671991","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}

There are many players in the market who benefit from DR, like the TSO, DSOs, retailers and end-customers themselves. The recent advent of smart grid technologies advanced the integration of DR by providing the needed information and communication infrastructure to the existing grid. Available literature on DR talks about the concept and definitions of DR, possible DR models for various region-specific market structures along with few DR implementation experiences in a system with ever increasing levels of loads along with evolution of innovative technologies like renewables, micro-grids, PEVs, etc. In this paper, the available literature on DR is categorized into general concept papers and papers on DR models applicable to the wholesale or retail markets, and are presented in a precise manner.","PeriodicalId":265646,"journal":{"name":"ISGT2011-India","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127753458","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 future SG, vast amount of data will be generated by smart meters, PMU based WAMS, SCADA and other monitoring devices. While research has been done to find suitable compression technologies to store power system disturbance and PMU data; there is lack of research on the storage of SCADA data which is basically steady state operational data of the grid. Presently, utilities store some important SCADA data for a limited period and then they either delete them or store them in unreliable manner (CD/DVD etc.). The investigations presented here explore the application of Principal Component Analysis based lossy compression technique for archiving the steady state operational data. Four important operational data - voltage, line flow, MW and MVAr generation are considered for the study. The effectiveness of the proposed method is evaluated considering practical data pertaining to the Southern Regional Grid of India.

This results in an increase of the net efficiency of the induction heating system. This system has an advantage like reduced volume and switching losses.

Distribution networks must be carefully controlled in order to maintain an acceptable power supply quality. In order to meet sustained load demands during varying natural conditions, different renewable energy sources need to be integrated with each other. This paper describes dynamic modeling and simulation results of a renewable energy based hybrid power system on the combination of solar cell ,fuel cell and wind turbine systems for power generation. Dynamic modeling of various components of this isolated system is presented. Transient responses of the system to step changes in the load, ambient temperature, radiation, and wind speed in a number of possible situations are studied. The results show that the proposed hybrid power system can tolerate the rapid changes in natural conditions and suppress the effects of these fluctuations on the voltage within the acceptable range. We designed a flexible DSP-controlled three-phase power electronic converter for the integration of distributed energy generation into networks. The further increase of energy conversion from renewable energy sources demands a share of the conventional centralized grid control. This requires a fast and flexible control system. The control is realized with embedded model details of DSC. The system structure, the special problems resulting from the use of a DSP-system and the implementation of the inverter control are described. The models have been developed by means of Simulink.","PeriodicalId":265646,"journal":{"name":"ISGT2011-India","volume":"17 2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130646710","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}

Plug-in Hybrid Electrical Vehicles (PHEV) have potential to increase the ability of residential customers to participate in demand response programs. Therefore, a new infrastructure that enables vehicle to participate in demand response programs is needed. Smart charging and discharging plans will lower the operational cost of electric vehicles and reduces peak system load. In order to identify the best solution, a decentralized Multi-Agent System (MAS), and a hybrid algorithm combined with an Evolutionary Algorithm (EA) and a Linear Programming (LP) were developed to manage a power distribution system with PHEVs in this paper. Outcomes of simulation studies show that a central scheduling system can obtain an optimal way of charging and discharging of PHEVs, but it is unfeasible in practice. Centralized methods require complete information on when and how much PHEVs are needed to charge and discharge beforehand. This is not available in practical systems. The multi-agent system approach proves that it is a scalable decentralized methodology which can adapt to incomplete and unpredictable information while the numerical outcomes are not much worse than that from a central scheduler.","PeriodicalId":265646,"journal":{"name":"ISGT2011-India","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130144864","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}
