14. PRÉ-DESPACHO DE POTÊNCIA ATIVA CONSIDERANDO AS ÓTICAS DOS AGENTES GERADORES E DO OPERADOR DO SISTEMA / PRE-ORDER IN ACTIVE POWER CONSIDERING THE OPTICIANS OF AGENTS GENERATORS AND SYSTEM OPERATOR
The restructuring and deregulation of electricity markets has caused signicant changes in electrical power systems in several countries. This process has result in a market-based competition by creating an open market environment. In this new environment each generation company runs the Unit Commitment to maximize their prots, and have no obligation to meet

15. Electricity generation from the offshore wind energy source. / Geração de energia elétrica a partir da fonte eólica offshore.
In the last decade wind power source was the fastest-growing energy source. Technological learning curves for this sector fall down by a 15% a 20% rate each 3 years. Countries which are committed with wind power are running after the target of 12% wind into the worlds electrical production by 2020. The contribution of the offshore wind power (OWP) source is

16. Análise da livre concorrência e competitividade no setor elétrico brasileiro / ANALYSIS OF FREE COMPETITION AND COMPETITIVENESS IN THE SECTOR ELECTRIC BRAZILIAN
In this work the relevant aspects of free competition and competitivity in the Brazilian electric sector after deregulation initiated in 1995 are analyzed. The earlier model of the electric sector, a State monopoly, moved for a desverticalized structure with the separation of the sectors of generation, transmission and distribution. With this scenario as bac

18. Gestão estratégica de energia elétrica e seus reflexos no desenvolvimento regional
Economic growth and increase of electric energy consumption are unquestioned historical facts and even nowadays, in developing countries, with a very strong correlation. However, the huge appropriation of energy resources and the residues emission in the nature caused by the industrial society had shown incompatible with a necessary environment sustainabilit

19. Modelo de Stackelberg na competição de empresas privadas e estatais pela expansão da oferta de energia eletrica / Stalckelberg model in the competition between state-owned and private firms for the expansion in the electric energy supply
The process of structural reform that has been occurring in the Brazilian electric industry since the second half of the 1990 s suffered an infiection in 2002. The programs of privatizations were interrupted, stabilizing a hybrid structure where state-owned and private firms coexist in the same market. This thesis intends to analyze the effect, in the econom

20. ESSAYS ON LIBERALIZATION, REGULATION AND INVESTMENT IN HYDROTHERMAL SYSTEMS / ENSAIOS SOBRE LIBERALIZAÇÃO, REGULAÇÃO E INVESTIMENTO EM SISTEMAS HIDROTÉRMICOS
This dissertation is structured into 3 essays in which I analyze the economic effects of regulation and liberalization of hydrothermal systems. So far empirical and theoretical studies about power markets have been done mainly for thermal systems, in which equilibrium conditions reflect the fact that current production decisions can be analyzed separately fr

21. OPTIMUM PRICE BIDDING STRATEGY IN THE SHORT-TERM MARKET OF HYDRO-DOMINATED ELECTRIC SYSTEMS / ESTRATÉGIA ÓTIMA DE OFERTA DE PREÇOS NO MERCADO DE CURTO PRAZO EM SISTEMAS COM PREDOMINÂNCIA HIDRELÉTRICA
In perfectly competitive markets, there are no loopholes that can be exploited by agents to maximize profit through non-competitive behavior. However, electricity markets look more like an oligopoly than perfectly competitive markets. If competition is not perfect, generation agents may try to establish optimum price bidding strategies to maximize profits. I

22. COMPETITION IN ELECTRIC ENERGY SYSTEMS - COMMERCIALIZATION AND STRATEGIES TO THE MARKETS / COMPETIÇÃO EM SISTEMAS DE ENERGIA ELÉTRICA COMERCIALIZAÇÃO E ESTRATÉGIAS PARA O MERCADO
Electricity utilities all over the world have been undergoing radical changes in their market and its regulatory structure. A basic trend in this restructuring process has been to promote competition in generation, distribution/retailing segments and participation of private agents in the energy production process. This restructuring is based on centralized

23. Utilização do Gás natural de Camisea (Peru) para a Viabilização de Sistemas Elétricos e de Gás no Norte e Centro Oeste do Brasil / Use of Natural Gas Camisea (Peru) for Feasibility of Gas and Electric Systems in North and Central Western Brazil
The Cemisea´s natural gas reserves should play a major role in the natural gas and electricity market development in the southern region of Latin America (Argentina, Bolivia, Brazil, Chile, and Peru). As the development of the Camisea gasfields will considerably exceed the existing demand in Peru, the supply of natural gas could be oriented to more profitab
