The point forecast is estimated via the gradient boosting machine (GBM). The mean of the error distribution is assumed to be zero, and the standard deviation (STD) of the error distribution is found to minimize the sum of the mismatches between the quantiles of the error distribution and the actual target value. The mismatch is measured by the pinball loss function, and the optimal STD is found through the golden section search method. The performance of our proposed algorithm is verified by using the numerical weather prediction (NWP) and wind power data from the 2014 Global Energy Forecasting Competition (GEFCom). Our current benchmark ranking is second according to the published competition result of 14th week.","PeriodicalId":6497,"journal":{"name":"2016 IEEE/PES Transmission and Distribution Conference and Exposition (T&D)","volume":"28 1","pages":"1-5"},"PeriodicalIF":0.0,"publicationDate":"2016-05-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78790470","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 primary feature of the system presented here is its very low cost compared to more traditional inspection methods, because the process takes place entirely in virtual space. Specifically, the system can locate assets with a precision comparable to typical GPS units used for similar purposes, and can readily identify utility assets, for example transformers, if appropriate training data are provided. Further human intervention would only be necessary in a small fraction of cases, where very high uncertainty is flagged by the system. The feasibility of the process is demonstrated here, and a path to full integration is presented.","PeriodicalId":6497,"journal":{"name":"2016 IEEE/PES Transmission and Distribution Conference and Exposition (T&D)","volume":"71 1","pages":"1-5"},"PeriodicalIF":0.0,"publicationDate":"2016-05-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90239523","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 intermittency of the input source and system components availability were modeled separately and then convolved to construct a single capacity outage table. The discrete convolution method has been used in this work to build a generation model in the form of a capacity outage probability table. The proposed method is applied on the RBTS. The obtained results are compared to the results obtained by Monte Carlo simulation.

In this paper a comprehensive, simplified method for determining the location of developing problems within a power transformer will be provided, which includes overheating leads, core, main winding paper, de-energized tap changers (DETC).

The modifications entail the inclusion of the current elements of current sources in the Jacobian matrix of the NR algorithm. The effect is to enable current controlled sources to be modeled directly in the power flow algorithms without the need for converting their currents to the corresponding power components, which is the traditional practice in power flow algorithms. The proposed algorithm has been tested on an IEEE 14-bus system. For loop systems with current controlled sources, the test results show that using this algorithm for power flow analysis offers enhanced accuracy.","PeriodicalId":6497,"journal":{"name":"2016 IEEE/PES Transmission and Distribution Conference and Exposition (T&D)","volume":"105 1","pages":"1-5"},"PeriodicalIF":0.0,"publicationDate":"2016-05-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76662597","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 screening is needed as during a permanent fault, the fault current maybe interrupted by multiple operations of protection devices (PDs), and therefore determining the proper fault current for the model based fault locating method (FLM) becomes challenging. The Event Screening Method analyzes the all the events captured by the fault monitoring device (usually a PQ monitor) and determines the proper fault information needed by FLM. Test results for the improved FLM with Event Screening integrated are provided using a real distribution feeder. The results show that the Event Screening Method is able to accurately predict the operating sequence of PDs during a fault and that the improved FLM can accurately locate the faulted zone.","PeriodicalId":6497,"journal":{"name":"2016 IEEE/PES Transmission and Distribution Conference and Exposition (T&D)","volume":"40 1","pages":"1-5"},"PeriodicalIF":0.0,"publicationDate":"2016-05-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72677475","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}
