A successful low-voltage ride-through (LVRT) scheme is a key requirement to achieve reliable and uninterrupted electrical power generation for wind turbines equipped with doubly fed induction generators (DFIGs). This paper proposes a feed-forward transient current control (FFTCC) scheme for the rotor side converter (RSC) of a DFIG to enhance its LVRT capability. This new control scheme introduces additional feed-forward transient compensations to a conventional current regulator. When three phase faults occur, these compensation terms correctly align the RSC ac-side output voltage with the transient-induced voltage, resulting in minimum transient rotor current and minimum occurrence of crowbar interruptions. With little additional computational effort, the proposed control scheme helps relieve the transient current stress on the RSC and helps maintain an uninterrupted active and reactive power supply from the wind turbines to the power grid. Simulation results are shown to demonstrate the effectiveness of the proposed FFTCC scheme in suppressing transient rotor currents.","PeriodicalId":120665,"journal":{"name":"2011 IEEE/PES Power Systems Conference and Exposition","volume":"395 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122201815","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}

Instead of traditional off-line testing, this process supports validation of dynamic models for generators and their governor, excitation, and stabilizer systems using data gathered while the units are on-line. The approach is based on using digitally recorded unit responses to system disturbances. Continued model validation is necessary to ensure generating units are simulated correctly. Model validation is imminently to be mandated by the North American Electric Reliability Corporation (NERC) through its modeling, data, and analysis standards. The benefits of the model validation method presented here are explained when compared to traditional techniques, which typically include collecting data from a series of mostly off-line staged tests. The comprehensive process of model validation and a review of the key-limitations of this process are also discussed. Lastly, the paper presents the successful application of this technique to three large thermal units for the purpose of WECC generator model validation and certification. Key results of the case studies are reported together with fruitful insight into the limitations of some of the models available for power plant modeling in planning studies.","PeriodicalId":120665,"journal":{"name":"2011 IEEE/PES Power Systems Conference and Exposition","volume":"190 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116517209","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}

These assets pose challenges to grid reliability and power quality. One critical challenge is islanding (inadvertent system separation) detection, separation, and eventual resynchronizing. Research is underway to devise best practice methods for appropriate islanding control for all load and generation conditions. Wide-area measurements such as synchrophasors provide an accurate means to detect islanding conditions by enabling precise time-synchronized measurements at diverse locations. This paper presents a real-time islanding detection system for PV-based generation that is representative of many types of DG. The system utilizes synchrophasor data collected at the PV location and elsewhere in the system to detect the islanded condition. The paper shows how synchrophasors are used to isolate the DG during such conditions. It also discusses the real-time modeling and closed-loop testing of the synchrophasor-based islanding detection system, which includes the PV-based inverter and the power distribution system. The effectiveness of the system was experimentally tested on a live power system. An evaluation is also presented for using synchrophasors to resynchronize the islanded system.","PeriodicalId":120665,"journal":{"name":"2011 IEEE/PES Power Systems Conference and Exposition","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128077518","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}

It facilitates the employment of computer technology and communication infrastructure to advance management and operation of the distribution network from a semi-automated approach towards a fully automated one. SCADA systems, advanced sensors, and electronic controllers are integrated into the DA system in order to achieve the desired performance and reliability at the distribution network. Interoperability of all the components participating in the DA system requires communication standards covering not only the devices in the substation, but all the components from the substation to the point of interface with the end consumers. While the IEC 61850 standard was originally addressing applications and communications within the substation, recent work is undergone for extending it beyond the substation fence. With its object oriented structure, IEC 61850 can provide comprehensive and accurate information models for various components of distribution automation systems, while providing an efficient solution for this naturally multi-vendor environment. This paper provides some concrete examples on how IEC 61850 can be employed in the context of distribution automation applications, and what measures need to be taken to enable it to efficiently respond to some of the emerging technologies in DA systems.","PeriodicalId":120665,"journal":{"name":"2011 IEEE/PES Power Systems Conference and Exposition","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121860553","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}

It is the ultimate \"just-in-time\" system, required by the laws of physics to carry no inventory. This characterization is again under challenge, as development of grid scale energy storage devices, both electrochemical and mechanical, is accelerating and being represented as a critical piece of the grid infrastructure of the future. Much of the impetus behind this activity follows closely with the early days of meaningfully high penetrations of renewable generation into our power systems, at both the transmission and distribution-level; each of which presents somewhat different challenges in terms of integrating wind and solar energy. Storage, it is argued, offers the stabilization and buffering capacity that will be necessary to reconcile the variability of growing amounts of renewable generation and the challenges these might cause with relatively predictable and stable loads. Our purpose in this paper is to introduce a few frameworks for consideration of both the necessity of grid scale energy storage for the reliable operation of the grid of the future as well as the economic propositions that these assets will face in developed electricity markets and under established utility practices. Simply put, there are three basic and obvious questions that must be addressed for any asset deployment: (1) what is the problem the asset will solve?; (2) what is the mechanism by which an investor would be able to recover the costs of the asset?; and (3) what other means are there of solving the same problem? This paper will consider each of these questions for a variety of applications of utility-scale energy storage.","PeriodicalId":120665,"journal":{"name":"2011 IEEE/PES Power Systems Conference and Exposition","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129995314","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}

These utility applications include Synchrophasors, CRAS, SCADA etc. During the same period, use of the enterprise network has moved from simple IP applications to an ever increasing number of advanced technologies being collapsed onto the IP infrastructure. These enterprise applications include video, telephony, storage and physical access security. As critical services such as Voice, Video and SCADA data converge on IP, the resiliency; scalability and availability of the WAN infrastructures become critical. The new converged network must adopt to meet the new stringent requirements while still maintaining flexibility and ease of operations. This paper will start by describing the services and the corresponding communication requirements that the future utility WAN must support. The paper will then propose various architecture models to satisfy the requirements. The paper concludes with comparison of the proposed models against various network optimization criteria.","PeriodicalId":120665,"journal":{"name":"2011 IEEE/PES Power Systems Conference and Exposition","volume":"84 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115875239","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}
