A Light, investimento estrangeiro no Brasil: uma luz sobre o ciclo privado-público-privado em 80 anos pela análise de taxa de retorno

A Brazilian Traction, Light and Power Company ("Light"), formada por empreendedores canadenses em 1899, operou por 80 anos praticamente toda a infraestrutura (bondes, luz, telefones, gás) do eixo Rio-São Paulo. A empresa passou por vários ciclos políticos, desde sua fundação até sua estatização em 1979. Durante este período de 80 anos, a infra-estrutura nacional, inicialmente privada, foi gradativamente passando para as mãos do Estado. O setor voltaria a ser privado a partir dos anos 90, configurando o ciclo privado-público-privado, similar ao ocorrido nos países mais desenvolvidos. A Light, símbolo maior do capital estrangeiro até os anos 50, foi inicialmente bem recebida no país, posto que seu desenvolvimento era simbiótico, causa e conseqüência, ao desenvolvimento industrial. Dos anos 20 em diante, crescem os debates econômicos ou ideológicos quanto ao papel do capital privado estrangeiro no desenvolvimento nacional, vis-a-vis a opção do setor público como ator principal. Sempre permaneceu sob névoa quais teriam sido os lucros da Light no Brasil, e se esses seriam excessivos, acima do razoável. Outra questão recorrente se refere até que ponto os congelamentos de tarifas teriam contribuido para a crise de oferta de infra-estrutura. Através de um trabalho de pesquisa em fontes primárias, esta dissertação procura reconstituir a história da Light, sob um foco de Taxa de Retorno sob o capital investido. Foi reconstruída a história financeira da Light no Brasil, a partir da qual calculou-se, para vários períodos e para os seus 80 anos de vida, os retornos obtidos pelos acionistas da empresa. A partir dos resultados obtidos, e utilizando-se de benchmarks comparativos, foi possível mostrar que: i) ao contrário da crença vigente à época, o retorno obtido pelo maior investidor estrangeiro no setor de infra-estrutura do Brasil do Séc. XX, se mostrou bem abaixo do mínimo aceitável, e ii) o represamento de tarifas, por várias décadas, foi de fato determinante para o subdesenvolvimento do setor de infra-estrutura no Brasil.

Optimal sitting and sizing of distributed generators considering plug-in electric vehicles

Some uncertainties such as the stochastic input/output power of a plug-in electric vehicle due to its stochastic charging and discharging schedule, that of a wind unit and that of a photovoltaic generation source, volatile fuel prices and future uncertain load growth, all together could lead to some risks in determining the optimal siting and sizing of distributed generators (DGs) in distributed systems. Given this background, under the chance constrained programming (CCP) framework, a new method is presented to handle these uncertainties in the optimal sitting and sizing problem of DGs. First, a mathematical model of CCP is developed with the minimization of DGs investment cost, operational cost and maintenance cost as well as the network loss cost as the objective, security limitations as constraints, the sitting and sizing of DGs as optimization variables. Then, a Monte Carolo simulation embedded genetic algorithm approach is developed to solve the developed CCP model. Finally, the IEEE 37-node test feeder is employed to verify the feasibility and effectiveness of the developed model and method.

Multilayer Perceptron Neural Networks Training Through Charged System Search and its Application for Non-Technical Losses Detection

The non-technical loss is not a problem with trivial solution or regional character and its minimization represents the guarantee of investments in product quality and maintenance of power systems, introduced by a competitive environment after the period of privatization in the national scene. In this paper, we show how to improve the training phase of a neural network-based classifier using a recently proposed meta-heuristic technique called Charged System Search, which is based on the interactions between electrically charged particles. The experiments were carried out in the context of non-technical loss in power distribution systems in a dataset obtained from a Brazilian electrical power company, and have demonstrated the robustness of the proposed technique against with several others natureinspired optimization techniques for training neural networks. Thus, it is possible to improve some applications on Smart Grids.

Effects of Air Pollution Control on Climate

Urban air pollution and climate are closely connected due to shared generating processes (e.g., combustion) for emissions of the driving gases and aerosols. They are also connected because the atmospheric lifecycles of common air pollutants such as CO, NOx and VOCs, and of the climatically important methane gas (CH4) and sulfate aerosols, both involve the fast photochemistry of the hydroxyl free radical (OH). Thus policies designed to address air pollution may impact climate and vice versa. We present calculations using a model coupling economics, atmospheric chemistry, climate and ecosystems to illustrate some effects of air pollution policy alone on global warming. We consider caps on emissions of NOx, CO, volatile organic carbon, and SOx both individually and combined in two ways. These caps can lower ozone causing less warming, lower sulfate aerosols yielding more warming, lower OH and thus increase CH4 giving more warming, and finally, allow more carbon uptake by ecosystems leading to less warming. Overall, these effects significantly offset each other suggesting that air pollution policy has a relatively small net effect on the global mean surface temperature and sea level rise. However, our study does not account for the effects of air pollution policies on overall demand for fossil fuels and on the choice of fuels (coal, oil, gas), nor have we considered the effects of caps on black carbon or organic carbon aerosols on climate. These effects, if included, could lead to more substantial impacts of capping pollutant emissions on global temperature and sea level than concluded here. Caps on aerosols in general could also yield impacts on other important aspects of climate beyond those addressed here, such as the regional patterns of cloudiness and precipitation.
