An improved s-domain model based on dynamic phasor approach was used to obtain the results presented in the paper. The study is conducted on the System-1 of the IEEE Second Benchmark Model. Detailed eigenvalue analyses are carried out in order to evaluate the effect of the proportion of TCSC to FSC, Boost Factor and size of TCSC reactor on subsynchronous damping. The influence of constant current controller and synchronization system (PLL) parameters is also investigated. Finally, a simple Subsynchronous Damping Controller (SSDC) is added to the TCSC main control in order to demonstrate that the SSR damping capability of TCSC may be enhanced by proper modulation of firing angle. The results obtained in the time domain simulations are validated through PSCAD/EMTDC simulations.","PeriodicalId":222318,"journal":{"name":"2010 IEEE/PES Transmission and Distribution Conference and Exposition: Latin America (T&D-LA)","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115110270","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}

Methodologies that allow what-if analysis involving simulation of spot price scenarios and energy contract's performance evaluation, are important to the decision maker and in particular to the trader, in order to foresee opportunities and possible threats in the energy market. The best solution to the problem of energy contracts portfolio optimization is a tradeoff solution, involving both risk and return, where the decision maker can know the worst scenarios of contracting and the spot market price. This paper proposes an approach for solving the contracts portfolio optimization problem by using Multi Objective Genetic Algorithm. In this approach, the risk metrics VaR and CVaR are considered as constraints in the construction of the Pareto Efficient Frontier.","PeriodicalId":222318,"journal":{"name":"2010 IEEE/PES Transmission and Distribution Conference and Exposition: Latin America (T&D-LA)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129817760","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 consists in large shunt capacitor banks, arranged as a C-type harmonic filter, connected to the high voltage system to provide reactive compensation and harmonic control, but with reduced losses in the resistor at fundamental frequency by means of a resonance between the reactor and auxiliary capacitor.

Under this scenario, the power electronics technology plays a vital role in managing an effective grid integration of the PV system, since it is subject to requirements related not only to the intermittent source itself but also to its effects on the grid operation. This paper proposes an improved structure of power conditioning system (PCS) for the grid integration of PV solar systems. The topology employed consists of a three-level cascaded Z-source inverter and allows the flexible, efficient and reliable generation of high quality electric power from the PV array. A full detailed model is described and its control scheme is designed. Validation of models and control schemes is carried out through digital simulations using the MATLAB/Simulink environment.","PeriodicalId":222318,"journal":{"name":"2010 IEEE/PES Transmission and Distribution Conference and Exposition: Latin America (T&D-LA)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129153027","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 concept of selfneutralized current is reminded in order to explain why the utilization of a double ACSR ground wire 7–20 km from the transmission line terminal substations is able to reduce up to 65% the value of the terminal substation ground mat current. It is also shown that, for power cables with metallic shielding grounded in both terminal substation ground mats, the reduction of mat current can be as large as 99.5%. The article reminds that these procuderes are already successfully used in several high voltage power substations now in operation. Some equivalent circuits are presented in order to allow a simple calculation of the value of the mat current (IM), using ACSR ground wires close to the terminal substations. It is also reminded that Steinmetz Circuit Theory has several advantages over the direct utilization of Maxwell Equations when computing A.C. transmission metallic circuits.","PeriodicalId":222318,"journal":{"name":"2010 IEEE/PES Transmission and Distribution Conference and Exposition: Latin America (T&D-LA)","volume":"105 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121781657","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}
