1. Desenvolvimento de modelos e algoritmos sequenciais e paralelos para o planejamento da expansão de sistemas de transmissão de energia elétrica / Development of mathematical models, sequential and parallel algorithms for transmission expansion planning
The main objective of this study is to propose a new methodology to deal with the long-term transmission system expansion planning with multiple generation dispatch scenarios problem (TEP-MDG). With the methodology proposed in this thesis we aim to build expansion plans with minimum investment cost and also capable of meeting the new demands of modern electr

2. Despacho ótimo de potência reativa baseado em custo de oportunidade via otimização em dois níveis
Esta dissertação apresenta um modelo de despacho ótimo de potência reativa baseado na minimização do custo de oportunidade dos geradores. A representação do custo de oportunidade é simplificada, de forma que o modelo de despacho possa ser expresso como um problema de otimização em dois níveis. Os objetivos do trabalho são analisar os resultados

3. Controlador supervisório inteligente para sistemas híbridos eólico-diesel-bateria de pequeno porte. / An intelligent supervisory controller for wind-diesel-battery systems.
This work presents the development and simulation results of an Intelligent Supervisory Controller for hybrid power systems. The controller uses artificial intelligence techniques, based on artificial neural networks and neuro-fuzzy logic, to forecast both wind power and load, and to take optimal dispatch decisions for hybrid power systems. The main controll

4. Optimal dispatch of generating units in hydroelectric systems by heuristic based on langrangean relaxation and dynamic programming / Despacho otimo de unidades geradoras em sistemas hidreletricos via heuristica baseada em relaxação lagrangeana e programação dinamica
The daily scheduling operation of the electrical energy system has by target to find the dispatch generation to the next day which must be compatible with the daily generation target defined by the energy planning models and to be an operational guide. Because of its proximity with the real time operation the modeling must represent the main characteristic o

5. Planejamento de curto prazo da operação incluindo criterios de estabilidade de tensão
This work presents a methodology to incorporate voltage stability criteria on power system short-term operation planning. The method consists of an active/reactive power re-dispatch for normal operation, and also a minimum load shedding strategy in case of critical contingencies, based in the direction provided by the participation factors obtained from the

6. 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
