1. Decomposition approach for generation and transmission expansion planning with implicit multipliers evaluation
In an electric power systems planning framework, decomposition techniques are usually applied to separate investment and operation subproblems to take benefits from the use of independent solution algorithms. Real power systems planning problems can be rather complex and their detailed representation often leads to greater effort to solve the operation subpr

2. Metaheurística para o Problema de Planejamento de Redes de Transmissão de Energia Elétrica com Redimensionamento / Metaheuristics for the transmission expansion planning problem with redesign
At times, the electrical load in dierent areas varies, claiming the construction of new electric generators and the expansion of the electrical transmission network. In this dissertation we focus on the transmission expansion planning problem, assuming that new generators are built to meet the new demands. This expansion requires large investments, which nee

3. 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

4. Análise da distribuição espaço-temporal da leishmaniose visceral e perfil clínico-epidemiológico dos casos e óbitos, Belo Horizonte Minas Gerais, 1994 a 2009
Since the decade of 1980, the visceral leishmaniasis (VL) has expanded to major urban centers of Brazil. Several factors contribute to this situation and among them the great mobility of populations, environmental changes and the increase in population density, which promote contact between humans, vectors and other animals. In this latter group the dog is t

5. Um estudo de planejamento da expansão da transmissão em sistemas de potência considerando a incerteza
This work presents the development of a model for long term transmission expansion planning, which considers the system security (N-1 criterion), the cost of congestion, the impact of new facilities in system operation and the risk associated to demand growth uncertainty. It is proposed in the planning methodology the usage of load curtailment tolerance rela

6. "Afundamentos de tensão no contexto da expansão dos sistemas elétricos: proposta de índices considerando dados do sistema de detecção de descargas atmosféricas"
The impact of voltage sags to power utilities and consumers has been remarking this event as a relevant phenomenon to address in power system studies. It is considered one of the most frequent sources of power-supply interruption and malfunction on several types of equipment, resulting in power-quality degradation. Nowadays, voltage sag has been basically ad

8. Automação como recurso de planejamento de redes de distribuição de energia elétrica. / Automation as resource for distribution systems planning.
Concerning the components of an electrical distribution network and their susceptibility to functional failures or need for maintenance actions, planning and project criteria should be adopted to assure continuity of energy supply even though some components may be out of work. Traditionally the power systems, especially in power transmission and distributio

9. Analysis of participation of energy self producers and independent producers in the Brazilian electric sector. / Análise da participação dos autoprodutores e produtores independentes de energia no setor elétrico brasileiro.
Historically, the electric power supply in Brazil has a role that stands out in the domestic economic growth, due to its capacity to add revenue through the promotion to large-sized industries. Its strong association in the composition of the domestic revenue is of general concern of all individuals involved and interested in the power supply in Brazil, whic

11. Transmission systems expansion planning considering security and generation programming plans / Planejamento da expansão de sistemas de transmissão considerando segurança e planos de programação da geração
This Ph.D. thesis presents some proposals to solve the transmission network expansion planning problem, static and multistage, taking into account security constraints - (n _ 1) security criterium, and the transmission expansion planning to satisfy some generation programming plans. Trying to find optimal solutions to large scale power systems, the specializ
