The study is based on the lessons learned about prevention and management from the most representative incidents worldwide, as well as from the regulations governing reliability and related aspects in other countries. The most important subjects about the regulation of a country should make emphasis to avoid the occurrence or minimizing the impact of blackouts are identified. An analysis of the Colombian regulation is carried out discovering main deficiencies and leading to regulatory actions that may solve the deficiencies found.

Moreover, the manner in which angle and frequency perturbations travel throughout the power grid has been closely studied in the past. Such perturbations are known to propagate throughout the grid as a function of time and space. Using measurements from a wide-area frequency monitoring network (FNET), one can observe the electromechanical wave signature of power system events in frequency data. In this paper, a brief synopsis of FNET is presented along with an analysis of several generator tripping events. The analysis is comprised of several event location methods and resulting observations. The eventual goal of this research is to formulate a robust event location algorithm that can be used online and in real-time to locate with sufficient accuracy the hypocenter of power system events irrespective of utility boundaries","PeriodicalId":267582,"journal":{"name":"2006 IEEE Power Engineering Society General Meeting","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117268000","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 main purpose of this works is to verify the capability of the gate controlled series capacitor (GCSC) to mitigate SSR. For this study the GCSC was tested in conjunction with the first IEEE benchmark system. The actual possibility of controlling SSR was verified by digital simulation using the ATP/EMTP (alternative transients program/electromagnetic transients program). As a result it was shown that GCSC is a powerful device for controlled series compensation both for power flow control and SSR damping. It was shown also that in some case the GCSC can damp SSR even without a specific control. GCSC can also damp electromechanical power oscillations as shown in some simulations","PeriodicalId":267582,"journal":{"name":"2006 IEEE Power Engineering Society General Meeting","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117339974","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}

A more general SE method based on the minimum information loss (MIL) principle is proposed. The new method is suitable for different probability distributions of measurement errors, it can utilize different types of information including that of analog and digital measurements, and a unified estimation of power flow and network topology can be performed by it. It is proved that weighted least square (WLS) and weighted least absolute value (WLAV) estimation methods are both special cases of the MIL estimation. Based on the MIL method, it is concluded that large magnitude currents are the approximate condition of WLS estimations for current magnitude measurements commonly used in SE's for sub-transmission and distribution networks.

The proposed security constraint is derived by applying a non-linear surface fitting technique to a database generated off-line. The technique used has two key features that enables very fast computation of an accurate transient stability constraint. One feature is that it uses a linear estimation technique to estimate a non-linear function by means of a non-linear transformation. The second important feature is that it employs an implicit technique to gain significant reduction in computing burden. The security constraints derived for each credible contingency can be used in an optimal power flow program for market clearance. The effectiveness and efficiency of the proposed method is demonstrated using the New England 39 bus system and a larger power system with 470 buses","PeriodicalId":267582,"journal":{"name":"2006 IEEE Power Engineering Society General Meeting","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127537571","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}

In the current economic dispatch practice only optimal active power allocation is considered since all cost functions are characterized as functions of the active power. Reactive power requirements are mostly mandated by utilizing a fixed power factor or based on system operators' judgment. In this proposal we consider making use of generator reactive capability curves to better characterize generation cost. With the new description of the actual generation cost, system dispatchers can achieve further reduction in overall system-wide generation cost while utility companies can make optimized decisions to improve their profit bottom line. Economic dispatch formulations are presented in this paper from both minimizing cost and maximizing profit perspectives. A simple power network is utilized for illustrating the key concept and gaining insight","PeriodicalId":267582,"journal":{"name":"2006 IEEE Power Engineering Society General Meeting","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125071914","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}

Firstly, SNB curves of all buses are calculated by CPF. Then voltage magnitude variation is adopted to find weak voltage buses under the same load variation rate. The buses, which have bigger normalized DeltaV , are chosen as weak voltage ones. We use the rate of voltage magnitude variation as grouping standard and present two indices (in time domain and frequency domain) for weak voltage buses group similarity. A fuzzy maximal tree is constructed to group the weak voltage buses according to their similarities and in consideration of the geographic factors. To locate the PMUs equally and sparsely, we introduce incomplete observability for PMU configuration as well as the placement rule.
