The study is based on a multiobjective formulation involving economical, technical and environmental aspects, and it consists of determining the quantity of units of each power plant that will be inserted in a distribution network by planning stage, considering some known specifications, expansion sceneries and constraints. The modeling aims to obtain a Pareto frontier set of solutions, which is addressed utilizing a multiobjective Particle Swarm algorithm and the Maximin metric. An application example is presented to test the proposed procedure; a metric to measure the diversity of the obtained frontier is employed, and the Max-Min approach is used as decision criterion.","PeriodicalId":222318,"journal":{"name":"2010 IEEE/PES Transmission and Distribution Conference and Exposition: Latin America (T&D-LA)","volume":"193 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":"127639781","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 project was based on a real case study in which three different voltage regulation techniques (Constant Voltage, Load Line, and Line Drop Compensation (LDC)) were implemented in a substation of a Brazilian utility of electric energy distribution. Measurements were performed at various points across one of the distribution feeders belonging to this substation. The comparative study among the methodologies took into account the local regulations, in special, the chapter 8 of the Procedures of Power Distribution of the National Electric System (PRODIST). The advantages and drawbacks of each methodology discussed in this paper are grounded in practical experiments in the real system. Studies and analysis suitable for each distribution system typology and load will allow, in the near future, the use and dynamic adjustment through a control center. Also, the use of Artificial Intelligence techniques will allow, in real time, the choice of the more appropriate regulation methodology for each case, using smart grid technologies.","PeriodicalId":222318,"journal":{"name":"2010 IEEE/PES Transmission and Distribution Conference and Exposition: Latin America (T&D-LA)","volume":"7 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":"128031171","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 explores the evolution of the electrical system by considering the example of the Colombian Power system.

Load following is the major area of impact when it comes to daily operation. The required load following service is addressed in two stages; day-ahead and intraday markets. This paper focuses on the day-ahead market that employs wind curtailment as a tool to control the ramping requirement of the residual demand, thereby, reducing the reliance on the expensive but flexible peaking units for load following purposes. The theoretical concept is provided and backed by simulation results and subsequent analysis.","PeriodicalId":222318,"journal":{"name":"2010 IEEE/PES Transmission and Distribution Conference and Exposition: Latin America (T&D-LA)","volume":"601 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":"132968255","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 DC system under study is assumed mainly dependent on renewable energy sources. The proposed topology utilizes a controlled series current compensator (CSCC) technique for connection and power flow control among buses. The proposed topology allows full power flow control among different DC buses while keeping the voltage level constant at all of them. Hence, loads connected to these buses will not be affected with the power flow process. Moreover, connection of buses at different voltage level and controlling the power flow can be easily achieved using this topology. The proposed topology reduces the complexity of applying protection schemes as it utilizes isolated DC-DC converter. Simulation results verified the applicability of the proposed topology. Moreover, a prototype system has been designed and built in hardware to examine the performance of the proposed system. The experimental results show the validity of the proposed system as a powerful technique to interconnect DC buses.","PeriodicalId":222318,"journal":{"name":"2010 IEEE/PES Transmission and Distribution Conference and Exposition: Latin America (T&D-LA)","volume":"33 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":"122186543","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}
