25. APLICAÇÃO DE FLUXO DE POTÊNCIA PROBABILÍSTICO NO PLANEJAMENTO DA EXPANSÃO DE SISTEMAS DE POTÊNCIA / APPLICATION OF PROBABILISTIC LOAD FLOW THE EXPANSION PLANNING OF POWER SYSTEMS
This dissertation presents an application of Probabilistic Load Flow (PFL) techniques to the expansion planning of power systems. A brief review of the PFL formulation and solution is included to identify differences between this technique and other available tools such as composite generation and transmission reliability evaluation algorithms. The potencial

26. PROBABILISTIC POWER FLOW: THEORY AND APPLICATION / FLUXO DE POTÊNCIA PROBABILÍSTICO: TEORIA E APLICAÇÃO
A Probabilistic Power Flow Algorithm (PPF) allows the practical evaluation of the probability of occurrence of power system events, based on their historical performance, load forecast and availability of generating units and transmission equipment. Such events are overlads, undervoltages, overvoltages and indufficiency of active/reactive power generation. T

28. PLANEJAMENTO DE EXPANSÃO DE SISTEMAS DE TRANSMISSÃO DE ENERGIA ELÉTRICA, COM OTIMIZAÇÃO DE CUSTOS / EXPANSION PLANNING OF POWER TRANSMISSION SYSTEMS WITH COST OPTIMIZATION
The plannification of the transmission system expansion is a very complex problem. In this work it is proposed a mathematical programming model to solve it, taking in account the restrictions established by the brazilian electric sector. It is shown the characteristics of some technics for solving the problem and a brief description of the transmission netwo

30. Power Generation and the Environment
Environmental factors will play an ever-increasing role in planning for the location and design of future power generating plants. This planning must include all phases of furnishing electric power, such as the exploration for and mining of fossil and nuclear fuels; the transportation and storage of these fuels; power plant siting; the disposal of solid wast
