As energias renováveis têm lugar de destaque entre as soluções de combate ao aquecimento global, mas seu potencial ainda é subaproveitado no Brasil. Este trabalho visa apresentar argumentos político-estratégicos, socioambientais e econômico-financeiros necessários para viabilizar o desenvolvimento da comercialização de novas fontes de energias renováveis e, consequentemente, o estabelecimento de um mercado nacional maduro para estas fontes. São apresentadas justificativas socioambientais e técnicas para ampliar a produção de energia elétrica a partir de novas fontes renováveis como eólica, biomassa, solar e pequenas centrais hidroelétricas. Foi abordado o importante papel da política tarifária e o atual modelo do setor elétrico, assim como o forte impacto dos encargos e tributos sobre o preço final da energia e as questões relacionadas à revisão tarifária e seu impacto em áreas rurais e urbanizadas. Foi apresentado um cenário de participação das novas fontes de energias renováveis na matriz elétrica brasileira indicando o forte potencial de expansão destas fontes, valorizando a descentralização e diversificação da matriz para promoção da equidade e justiça e desvinculação entre o crescimento econômico e a ampliação da geração de energia. Foram apresentados vários modelos de mercado e concluiu-se que o modelo da competição no varejo é a melhor opção para a viabilização de uma comercializadora de novas fontes de energias renováveis. Foram apresentados estudos de casos em diversos países da Europa...

Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES); Pós-graduação em Engenharia Elétrica - FEIS; Este trabalho propõe uma nova abordagem na metodologia de operação para o inversor Boost monofásico, como estrutura base para o aproveitamento de fontes alternativas e renováveis de energia elétrica. Considerando-se que equipamentos eletro/eletrônicos convencionais em CA (corrente alternada) necessitam, normalmente, de níveis e formato de tensão diferentes daqueles fornecidos por essas fontes de energia, o inversor proposto é uma estrutura integrada que tem a capacidade de operar como conversor elevador de tensão e inversor, apresentando um número reduzido de componentes e rendimento maior, quando comparado às formas tradicionais de se associar em cascata o conversor elevador com o inversor. O projeto convencional do inversor fonte de corrente (CSI) exige uma indutância elevada de entrada, além disso, o modelo a pequeno sinais do CSI é semelhante ao do conversor Boost no modo de condução contínua, apresentando um zero no semi-plano direito na função de transferência para o controle da tensão de saída, sendo que este zero causa o conhecido efeito de fase não-mínima. Desta forma, uma metodologia especial de projeto é apresentada resultando numa indutância Boost reduzida e numa técnica de controle utilizando um sistema multi-malhas...

Apesar da geração de energia elétrica no mundo ainda ser majoritariamente oriunda de combustíveis fósseis e não renováveis, várias políticas de incentivo ao uso de fontes renováveis alternativas de energia têm sido desenvolvidas. Dentre estas fontes, a geração de energia elétrica a partir de sistemas fotovoltaicos conectados à rede se destaca devido à elevada taxa de crescimento dos últimos anos; pelas expressivas reduções de preço e por ser uma das tecnologias chave para a geração descentralizada de energia elétrica em áreas remotas. Alguns dos benefícios da geração distribuída a partir de sistemas fotovoltaicos conectados à rede são: postergação de investimentos em expansão nos sistemas de distribuição e de transmissão; baixo impacto ambiental e tempo reduzido de implantação; redução no carregamento das redes e de perdas; e diversificação da matriz energética. No entanto, observa-se que a fonte tem sido mais bem aproveitada em países com baixos índices de irradiação solar. Chile e Brasil, por exemplo, possuem excelente potencial solar e oportunidades semelhantes de investimento na tecnologia, mas restringiram a utilização da fonte basicamente a sistemas isolados. Neste contexto, algumas iniciativas no Brasil e Chile têm visado o desenvolvimento da energia solar fotovoltaica. Esta dissertação tratou de analisar comparativamente as principais barreiras enfrentadas pela geração distribuída a partir de sistemas fotovoltaicos conectados à rede e...

This paper presents technological solutions that intend to contribute both for the efficient production of electric energy from renewable non-pollutant sources (namely Wind and Sun) and to the improvement of power quality in the electrical systems. It proposes the development of low-cost and high-efficiency power controllers that optimize energy extraction from hybrid systems, constituted by photovoltaic solar panels and wind power turbines, in small renewable energy power plants. Main innovations are the use of a single microcontroller for both sources’ power control and the development of an interface between the DC link and the AC electrical system. This interface uses a control system based in the p-q theory that takes into account power quality issues. The paper also presents a cost study regarding products for renewable systems available in the market.; Fundação para a Ciência e a Tecnologia (FCT) - POCTI/ESE/41170/2001.

The concept of “Virtual Renewable Power Plants - VRPP” enables several positive factors for the electric integration of Renewable Energy Sources (RES), namely (a) the smoothing of time based fluctuation of the power delivered by the RES, (b) the use of the natural complementary of renewable resources availability (c) the establishment of synergies between different RES as well as the combination of their production. The present work aims to identify the synergies between wind and photovoltaic (PV) plants, regarding their daily profiles l complementarity and resource availability; as well as the technical and economic added value of a VRPP. Results show an increase of 5.3% in the capacity factor when 2 MWp of PV is added to an 8 MW wind farm, considering all infrastructural capacity limits. Moreover, additional results include the characterization and optimization of hybrid virtual wind-PV plants production profile.

Renewable energy sources such as solar and wind hold the potential for providing a significant portion of the U.S. energy requirements in the decades ahead. Unlike other energy sources their availability is determined by nonrandom events beyond the control of the consumer. In addition, macro-, meso-, and microclimatic conditions play a major role in determining the worth of such renewable energy sources to their owners. The worth of these new technologies will be a function of owner, location, and application as well as the traditional capital and operating cost, i.e., their worth to an owner in the southwest will be different form that to an owner in the northeast or the southeast. Dealing with energy sources, with geographic and sectorally specific energy values and with energy technologies with which we have little or no experience in the marketplace has created a set of challenges in analysis and modeling of these new technologies in competition with traditional energy technologies and with other emerging technologies. This paper will look at one simulation methodology for estimating the worth of renewable energy systems providing electricity, such as wind or solar photovoltaic power systems, and will discuss the interaction between such systems and traditional electric utilities with which they may or may not be integrated...

In declaring 2012 the international year of sustainable energy for all, the United Nations (UN) general assembly (2011) established at the personal initiative of the UN secretary general- three global objectives to be accomplished by 2030. Those goals are to ensure universal access to modern energy services (including electricity and clean, modern cooking solutions), to double the global rate of improvement in energy efficiency, and to double the share of renewable energy in the global energy mix. Some 70 countries have formally embraced the Sustainable Energy for All (SE4ALL) initiative, while numerous corporations and agencies have pledged tens of billions of dollars to achieve its objectives. As 2012 drew to a close, the UN general assembly announced a decade of sustainable energy for all stretching from 2014 to 2024. Sustaining momentum for the achievement of the SE4ALL objectives will require a means of charting global progress over the years leading to 2030. Construction of the necessary framework has been coordinated by the World Bank and Energy Sector Management Assistance Program (ESMAP) and the International Energy Agency (IEA)...

Defense Energy Seminar; Hybrid microgrids containing renewable energy sources represent a promising option for organizations wishing to reduce costs while increasing energy security and islanding time. A prime example of such an organization is the U.S. military, which often operates in isolated areas and whose reliance on a fragile commercial electric grid is seen as a security risk. However, incorporating renewable sources into a microgrid is di cult due to their typically intermittent and unpredictable nature. We use simulation techniques to investigate the performance of a hypothetical hybrid microgrid containing both wind turbines and fossil fuel based power sources. Our simulation model produces realistic weather forecast scenarios, which we use to exercise our optimization model and predict optimal grid performance. We perform a sensitivity analysis and explore the impact of the planning horizon on solution quality for day-ahead schedule optimization.

Há um cenário de agrave na indústria de energia elétrica no Brasil, por escassez de energia afluente na produção hídrica, exigindo maior acionamento térmico. Para o futuro, usinas predominantemente a fio dágua, que estão sendo inseridas, estarão pronunciando ainda mais essa necessidade. Por força da estruturação térmica, sobrarão mais emissões de gases de efeito estufa - GEEs e consumo de recursos fósseis por unidade de energia elétrica produzida. Este estudo visa testar a possibilidade de construção de um cenário futuro, eleito 2050, de fornecimento de energia elétrica no país, balizado na aceleração do uso das fontes renováveis, premissa postulada como alinhamento à busca de desenvolvimento sustentável para o país. É utilizada a pesquisa, análise e síntese, com abordagem sistêmica, e aplicação de indicadores eleitos fundamentais para alcance do objetivo. São sistematizados dados e informações existentes em diferentes tipos de documentos elaborados por autores e organizações nacionais e internacionais, e nos planos governamentais de expansão da produção de energia elétrica. A partir do referencial teórico metodológico adotado, os resultados obtidos demonstram que é possível estabelecer um planejamento de longo prazo baseado no uso renovável dos recursos de que o país dispõe...

Scaling up renewable energy, such as wind and solar, goes hand-in-hand with the expansion of transmission infrastructure. The richest solar and wind renewable energy sites are often located far away from consumption centers or existing transmission networks. Unlike fossil fuel-based power sources, renewable energy sources are greatly site-constrained and, for this reason, transmission networks need to be expanded to reach the renewable energy sites. Delivering transmission is a challenge, given the dispersion and granularity of renewable sources. Tapping a few hundred megawatts of renewable energy sources, such as wind and solar power, will likely require delivering transmission to several sites. Furthermore, transmission is also required to smooth out the variability of new renewable sources in a large geographical area. For these reasons, countries' renewable energy scale-up efforts are being challenged by the need for timely and efficient delivery of transmission networks. The objective of this report is to present emerging lessons and recommendations on approaches to efficiently and effectively expand transmission networks for renewable energy scale-up. The report focuses on the planning and regulatory aspects of transmission expansion that are relevant to transmission utilities and electricity regulators.

This paper proposes a multifunctional converter to interface renewable energy sources (e.g., solar photovoltaic panels) and electric vehicles (EVs) with the power grid in smart grids context. This multifunctional converter allows deliver energy from the solar photovoltaic panels to an EV or to the power grid, and exchange energy in bidirectional mode between the EV and the power grid. Using this multifunctional converter are not required multiple conversion stages, as occurs with the traditional solutions, where are necessary two power converters to integrate the solar photovoltaic system in the power grid and also two power converters to integrate an off-board EV battery charger in the power grid (dc-dc and dc-ac power converters in both cases). Taking into account that the energy provided (or delivered) from the power grid in each moment is function of the EV operation mode and also of the energy produced from the solar photovoltaic system, it is possible to define operation strategies and control algorithms in order to increase the energy efficiency of the global system and to improve the power quality of the electrical system. The proposed multifunctional converter allows the operation in four distinct cases: (a) Transfer of energy from the solar photovoltaic system to the power grid; (b) Transfer of energy from the solar photovoltaic system and from the EV to the power grid; (c) Transfer of energy from the solar photovoltaic system to the EV or to the power grid; (d) Transfer of energy between the EV and the power grid. Along the paper are described the system architecture and the control algorithms...

By 2020, 33% of California’s electric power sales will come from renewable energy sources due to California’s Renewable Portfolio Standard (RPS). This implies a 359% increase, from 23,000 GWh to more than 80,000 GWh, in renewable energy generation since 2002. Also by 2020, 21% of the sales will be from intermittent renewable resources (IRRs) that will incur integration costs due to required flexible ramping resources to balance power supply and demand of the California grid. The key parties implementing the RPS are divided on the integration cost values of IRRs. The California Public Utilities Commission (CPUC) requires that IOUs use a zero value for integration costs. This results in an inaccurate Net Market Value, a critical component in selecting new renewable resources. IRR generators also support a zero integration cost to avoid a diminution in value. Investor-Owned Utilities (IOUs) support a non-zero cost adder to ensure all costs are accounted to deliver the most cost-effective reliable energy to customers. Firm and reliable renewable energy generators prefer a non-zero cost adder to value dependable energy delivery. Finally, the California Independent Systems Operator (CAISO) with the CPUC acknowledge that integration costs may become significant as the renewable portfolio expands as additional IRRs commence operations. Per studies...

The Renewable Portfolio Standard (RPS) is a policy tool that requires a certain percentage of renewable energy to be included in the portfolio of electricity resources serving a state or a country. The main purpose of an RPS is to foster the development of renewable energy market, increase the energy security by reducing the dependence on the imported energy sources (oil, etc.), and, to provide environmental benefits from using more renewable energy. There are different approaches to the design and implementation of RPS in different states in U.S. and the degree of achieving a success of the policy differs also, depending on the design features. In 2004 New York has enacted an RPS that starts in 2006 and requires provision of at least 25% of electric energy from renewable energy sources by the year 2013. This study analyzes the design and implementation approaches of RPS in Arizona, Hawaii, Maine, Texas, and Wisconsin in order to determine the key design features that lead to a successful implementation of the policy in order to develop recommendations for RPS in New York and in other states that may implement an RPS. In order to evaluate the degree of success in the case-states an RPS Metric System was designed. It evaluates the target setting of the policy...

The purpose of this study is to analyze the quality of life of communities in the Marajó Island, in the state of Pará, after the  deployment of alternative sources of electricity generation. Given the need  for a  sustainable use of sources of energy and the need for the social and economic inclusion of local population with limited energy access, the purpose of this study is to understand to  what extent the implementation of projects for the use of alternative energy sources in Marajo, especially biomass, solar and wind, has contributed to the life standard of local communities. The methodology was based on a field study that used open-ended interviews with members of four communities that used these alternative sources, corresponding to 397 respondents. The study found that communities reported high satisfaction with the new generation sources and noticed improvements in life quality through relative gains in income and access to household appliances. However, access to income only occurred substantially and permanently in one of the communities surveyed.; O objetivo deste estudo é analisar a qualidade de vida de comunidades da Ilha do Marajó, no Estado do Pará, a partir da implantação de fontes renováveis de geração de eletricidade.
