For the elaboration of this map of references, the levels of the dam were established in order to adjust the operation of the system during the next two years upon the criteria of reliability, considering diverse profiles of generation of CVG EDELCA based on the application of generation schemes with hydraulic maximization or minimization of thermal generation. The base of the methodology is the simulation of the behavior of Guri dam, through a model that determines the level of the dam from a generation already defined by CVG EDELCA during a 24-month period. As a result a group of reference curves of different generation profiles was obtained, that indicate the operative scheme necessary to apply","PeriodicalId":406067,"journal":{"name":"2006 IEEE/PES Transmission & Distribution Conference and Exposition: Latin America","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129628710","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}

Energy balances in transformation points allow us to focalize losses. However, we would have to make measurements in each transformer in order to compare the amount of energy that has been delivered with the energy that has been billed. The EDC system contains over 15,000 transformation points. Therefore, it would be extremely complicated, both from the technical and economic point of view, to make measurements in each of these devices. This paper describes a state estimation methodology in real time for each transformation point. This allows us to determine the areas with the greatest amount of nontechnical losses across the radial distribution system. An example of the application of this methodology is provided using a real 12.47 kV distribution circuit with 20 transformation points","PeriodicalId":406067,"journal":{"name":"2006 IEEE/PES Transmission & Distribution Conference and Exposition: Latin America","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129649996","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 UPFC is implemented by using two voltage source converters which are connected through a common DC link capacitor. Each converter is coupled to the power system with a transformer. The paper deals with the mathematical modeling and analysis of a sinusoidal pulse width modulation (SPWM) based UPFC. A model-free approach for the selection of the controller may also be an acceptable solution. The design and simulation of a matrix PI controller and a fuzzy logic controller have been carried out. From the simulation results, it is demonstrated that it can control real and reactive power. Simulations using the electromagnetic transients program (ATP/EMTP) and MATLAB/Simulink program are shown.

Current optimization models of capacitor placement only consider losses reduction and voltage profile simultaneously, but the compensation cost and the load changes are not taken into account as part of the objective function. Also, the result may be not the best choice because this is a very large optimization problem and there are too many combinations. We present a general approach for the optimal solution of this problem considering all the parameters of the distribution system involved: capacitor cost, voltage, angle and load changes. An exhaustive search through all possible solutions is needed. Therefore, GA is an ideal candidate to solve this situation, Working with this algorithm, a Microsoft Excel program has been developed in order to answer the capacitor placement problem for any kind of radial distribution system","PeriodicalId":406067,"journal":{"name":"2006 IEEE/PES Transmission & Distribution Conference and Exposition: Latin America","volume":"53 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132395176","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 paper shows the application of PSO for optimal sizing and allocation of a static compensator (STATCOM) in a power system.
