One is the concept of line flow sensitivities for line reactances and the other is a congestion management method using these sensitivities. The proposed sensitivities are based on the DC method. The proposed congestion management method, whose purpose is to relieve congestion without influencing transactions, is carried out by changing reactances by means of FACTS devices. In this paper, we conduct simulations using the Ward & Hale 6 bus system and the IEEJ EAST 107 bus system, and compare the estimated values by the sensitivities with the ones calculated by changing reactances. Based on the simulation results, the validity of the proposed methods is confirmed.","PeriodicalId":380613,"journal":{"name":"2007 IEEE Power Engineering Society General Meeting","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134414279","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}

Brazil has led this process and in overall has auctioned about 25,000 average MW of contracts, involving about 65 billion USD in financial transactions, while Chile has carried out its first auction in 2006, involving about 1,300 average MW (30% of energy sales of the main interconnected Chilean system expected for 2010).

To ensure PMU accurately reflect system dynamic behavior, one must evaluate the dynamic performance of a PMU. PMU dynamic performance evaluation includes three aspects: PMU modeling studies, laboratory testing and field evaluation. This paper briefly reviews the general PMU model structure, and then continues on PMU dynamic performance evaluation from actual field measurements. Reasons for field evaluation include: (1) inappropriate field settings of a PMU would generate unexpected phasor measurements; and (2) many conditions can not be easily produced in a lab environment. PMU field evaluation includes aspects like time synchronization, timing inconsistency due to filtering, frequency calculation issues, parasitic oscillations/processing artifacts, etc. Actual WECC measurement examples will be presented. Dynamic PMU testing in a lab environment is explored with a special focus on PMU filtering characteristics. How the phasor quality would impact derived system dynamic characteristics is addressed in the later part of this paper.","PeriodicalId":380613,"journal":{"name":"2007 IEEE Power Engineering Society General Meeting","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129387830","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}

This division results in numerous data sharing issues that limit the ability to achieve secure operation and to enhance situational awareness. There is a great need to bring these two functions closer by means of integrating architectures. This paper illustrates how same-format power system data models and object-oriented architectures can be used to integrate the real-time operations with the operations planning environment. This integration has many advantages including compatibility of the data models, ability to perform thorough analysis of snapshot cases in the planning environment, ability to use powerful off-line tools as part of the real-time sequence, unification of the enterprise application suite, reduced complexity in engineering procedures, and reduction in the cost of training, software development, and database maintenance.","PeriodicalId":380613,"journal":{"name":"2007 IEEE Power Engineering Society General Meeting","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131224002","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 systems are interconnected to the medium voltage distribution network, but they can be also operated isolated from the main grid, in case of faults in the upstream network. One of the key benefits of microgrids is the potential to increase service quality by providing generation redundancy, where most needed. In this paper the effects of microgrids in increasing the service quality are assessed by calculating a set of reliability indices on a typical LV network with and without DG sources connected and coordinated in islanded operation.","PeriodicalId":380613,"journal":{"name":"2007 IEEE Power Engineering Society General Meeting","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133141887","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}
