13. UtilizaÃÃo de fatores locacionais de perdas no planejamento da expansÃo de sistemas de transmissÃo
This work presents a diagnosis and suggests changes to the planning criteria currently in use in the Brazilian electric sector, focusing on the way how to treat the electrical losses in the analyses for determining the expansion of the Basic Network, due to the recent creation of a methodology for calculating Loss Factors in the electrical system, considerin

14. ACQUISITION COST ALLOCATION OF REACTIVE POWER SOURCES / ALOCAÇÃO DO CUSTO DE CAPITAL DE FONTES DE POTÊNCIA REATIVA / ASIGNACIÓN DEL CUSTO DE CAPITAL DE FUENTES DE POTENCIA REACTIVA
This report presents three methods to identify the transmission consumers in power systems that take advantage of new or existent reactive power sources and, consequently, to allocate its acquisition costs among these consumers. The methodology to obtain the allocation factors, applied to each of the agents, takes into account the analysis of a transmission

15. Uma metodologia de planejamento da expansÃo da transmissÃo baseada em trade-off e indicador de mÃrito econÃmico
Since the last ten years the electrical industry have been experiencing an intensive restructuring process worldwide. This process varies from country to country in accordance with their characteristics. However a common objective has been identified: the increase in terms of efficiency through the introduction of competition in the energy production and tra

16. Otimização da expansão conjunta da geração e transmissão em sistemas hidrotermicos de potencia atraves do algoritmo de decomposição de benders e equacionamento das incertezas relativas as vazoes afluentes aos reservatorios, das usinas hidroeletricas, previsões do mercado e custo de instalação das novas usinas
A new approach is developed in this work for the joint generationltransmission expansion planning of hydrothermal electric power systems. The goal is to determine the generating capacity of the candidate plants, the commissioning dates of their generating units, their production scheduling, the new transmission lines and their voltage levels, as well as the

17. 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

18. Planejamento da expansão da geração de sistemas hidrotermicos de potencia, otimizando os usos multiplos da agua dos reservatorios
A substantial contribution to the development of generation expansion planninq for hydrothermal power systems is aimed at in this work. The possible multiple uses of the water from candidate hydro plant reservoirs are considered, employinq conversational techniques of multiobjective programminq. Initially, a modeling based on linear programming is presented

19. 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

20. 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
