Babita Jain, Manoj Kumar Nigam, Prem Chand Tiwari","doi":"10.1109/WICT.2012.6409098","DOIUrl":"https://doi.org/10.1109/WICT.2012.6409098","url":null,"abstract":"Short term load forecasting in this paper is done by considering the sensitivity of the network load to the temperature, humidity, day type parameters (THD) and previous load and also ensuring that forecasting the load with these parameters can best be done by the Regression Line Method (RLM) and Curve Fitting Method (CFM). The analysis of the load data recognizes that the load pattern is not only dependent on temperature but also dependent on humidity and day type. A new norm has been developed using the regression line concept with inclusion of special constants which hold the effect of the history data and THD parameters on the load forecast and it is used for the STLF of the test dataset of the data set considered. A unique norm with a, b, c and d constants based on the history data has been proposed for the STLF using the concept of curve fitting technique. The algorithms implementing this forecasting technique have been programmed using MATLAB. The input data of each day average power, average temperature, average humidity and day type of the previous year are used for prediction of power, in the case of the regression line method and the forecast previous month data and the similar month data of the previous year is used for the curve fitting method. The results are also compared with the Euclidean Norm Method (ELM) which is generally used method for STLF. The simulation results show the robustness and suitability of the proposed CFM norm for the STLF as the forecasting accuracies are very good and less than 3% for almost all the day types and all the seasons. Results also indicate that the proposed curve fitting method out passes the regression technique and the standard Euclidean distance norm with respect to forecasting accuracy and hence it will provide a better technique to utilities for short term load forecasting.","PeriodicalId":445333,"journal":{"name":"2012 World Congress on Information and Communication Technologies","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2012-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133299639","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}

Generally speaking, the utilization of a coupled inductor is useful for raising the step-up ratio of the conventional boost converter. However, the switch surge voltage may be caused by the leakage inductor so that it will result in the requirement of high-voltage-rated devices. This paper proposes a new high step-up dc-dc converter designed especially for regulating the dc interface between various micro-sources and a dc-ac inverter to electricity grid. The figuration of the proposed converter is a quadratic boost converter with the coupled inductor in the second boost converter. The converter achieves high step-up voltage gain with appropriate duty ratio and low voltage stress on the power switch. Additionally, the energy stored in the leakage inductor of the coupled inductor can be recycled to the output capacitor. The operating principles and steady-state analysis of continuous-conduction mode and boundary-conduction mode are discussed in detail. The simulation circuit is developed by using the MATLAB/SIMULINK modeling and the concerned characteristics are analysed.","PeriodicalId":445333,"journal":{"name":"2012 World Congress on Information and Communication Technologies","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2012-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124975342","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}

While joining a social network, the user is requested to fill up a lot of unnecessary information like educational background, birth date, interests etc. This information may get leaked or mal-accessed if not protected with proper security measures. The data stored in social network may be attacked in different ways according to purpose of attack. In this paper we identify basic types of privacy breaches in social network. Secondly, we study the concept of Hippocratic principles. We propose a simple classification of the information requested from the user when he joins the social network. We also propose a privacy preserving model based on Hippocratic principles, specifically for Purpose, Limited Disclosure, Consent and compliance. Our proposed model work on privacy metadata, query analyzer is extended to check the define policy before giving the result out. This model can be used while mining on private data, which will help to enhance the privacy level of trustworthiness among internet users.","PeriodicalId":445333,"journal":{"name":"2012 World Congress on Information and Communication Technologies","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2012-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123899219","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}
