The empirical mode decomposition (EMD) is used to detrend the frequency signal, and an auto-regressing moving-average (ARMA) model is used to describe the time series data and the modified yuler walker (MYW) algorithm is used to estimate the AR parameters.

Fault ride through (FRT) capability of a wind farm is very important, as it is a common requirement by the grid codes practiced all over the world. In this work, to enhance the FRT capability of a DFIG based wind farm, the parallel resonance fault current limiter (PRFCL) is proposed. To check the effectiveness of the proposed PRFCL, its performance is compared with that of the bridge-type fault current limiter (BFCL). A three-phase-to-ground (3LG) fault was applied to one of the double circuit transmission lines at the wind farm connection point of the multi-machine system to investigate the FRT capability. Simulations were carried out in Matlab/Simulink environment. Simulation results show that the PRFCL is a very effective auxiliary device to achieve better FRT. Moreover, it was found that the PRFCL outperforms the BFCL.","PeriodicalId":6497,"journal":{"name":"2016 IEEE/PES Transmission and Distribution Conference and Exposition (T&D)","volume":"39 27","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":"91514813","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}

Simultaneously, the refinery upgraded protective relaying to support IEC 61850 GOOSE messaging. New load caused a generation deficit when islanded from the local utility. The project team implemented a power management system to preserve critical loads when the refinery microgrid is islanded from the utility. The power management controllers use IEC 61850 GOOSE messaging. The project team performed thorough hardware-in-the-loop testing using a Real Time Digital Simulator (RTDS) along with traditional protection test-set testing to validate system operation for designed transitions and anticipated equipment failure modes. In studying these projects, we have developed a framework, which this paper shares, for successfully implementing other, similar microgrid power management system projects.","PeriodicalId":6497,"journal":{"name":"2016 IEEE/PES Transmission and Distribution Conference and Exposition (T&D)","volume":"161 ","pages":"1-4"},"PeriodicalIF":0.0,"publicationDate":"2016-05-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91554179","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 circuit equations are formulated in terms of voltages and currents in rectangular coordinates using a graph theoretic algorithm that provides for optimal numerical conditioning. A current-source based generator model is introduced that provides for more robust and efficient convergence as compared to our original approach. We show that the proposed framework supports nonlinear models with insensitivity to the initial guess and converges in few iterations. We illustrate the capabilities of generalized modeling by deriving a model for a grid-connected solar panel system that includes AC, DC and semiconductor components.","PeriodicalId":6497,"journal":{"name":"2016 IEEE/PES Transmission and Distribution Conference and Exposition (T&D)","volume":"27 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":"87151403","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 proposed methodology is formulated as a bi-level optimization problem to address the optimal and secure operation of multiple energy carrier microgrids.

They are usually switched in and out of the system according to the amount of connected load. This paper analyzes measurement data of a distribution utility with capacitor banks located downstream from the power quality monitor. It was observed that the amount of reactive power injected into the system was larger than the necessary, resulting in power factor over correction. The paper then provides an analysis method to determine the capacitor bank size to achieve a desired power factor correction. An algorithm is also proposed to override a switching control (usually time, voltage, or temperature), such that the switching is performed only if the power factor is below a preset minimum value. Moreover, it is advised to switch each phase individually, as the reactive power flow differs significantly between the three phases.","PeriodicalId":6497,"journal":{"name":"2016 IEEE/PES Transmission and Distribution Conference and Exposition (T&D)","volume":"18 2 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":"89056163","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}

Stability issues must, therefore, be considered during CEED. This paper presents a multi-objective formulation of CEED in a power system, with the competing objective functions of minimizing fuel cost and emission. Non-dominated Sorting Multi Objective Opposition based Gravitational Search Algorithm (NSMOOGSA) is used as an optimization tool. Fuzzy decision maker is used to extract the best compromise non-dominated solution.

Manufacturers have integrated Rogowski coil into high voltage GIS for current measurement and capacitive principle for voltage measurement. These concepts were realized in different types of products such as RC voltage dividers, external Rogowski coils in electronic current transformers (eCT), etc. Special electronic units for preprocessing and merging of sampled measured values have been developed to convert the outputs (low power or optical) to the standard IEC 61850-9-2- for each NCIT technology. This ensures the compatibility as well as interoperability of any protection device with the appropriate digital interface. Installed NCIT technology will provide many benefits for utilities and manufacturers, including reduction of SF6 insulation gas (environmental benefit), simplified wiring, and efficiency in manufacturing and engineering. Additional technical benefits include seamless-unified measurement and higher accuracy.
