“…In addition, wind speed, wind direction, and ambient pressure data were obtained from the Korean Meteorological Administration (KMA). Wind speeds were recorded at a height of 10 m, but taking the height of our greenhouse into account, the wind speed data were modified to the height of its eaves using the following power law Equation (1) [27]:…”

Abstract:Energy management of the greenhouse is considered to be one of the most important challenges of greenhouse farming. Energy saving measures need considered, besides applying energy supplying techniques. To address this issue, a model was developed to simulate the thermal environment of a greenhouse using a Transient Systems Simulation Program (TRNSYS 17) as a building energy simulation (BES) platform. The model was calibrated by modifying the input parameters to minimize the uncertainties obtained from the results. Nash-Sutcliffe efficiency coefficients of 0.958 and 0.983 showed good agreement between the computed and experimental results. The proposed model was used to evaluate the effects of greenhouse design parameters, including roof shape, orientation, double-glazing, natural ventilation, coverings and their thickness, on its energy conservation capacity. It was found that the most suitable design for a greenhouse located in Daegu (latitude 35.53 • N, longitude 128.36 • E) South Korea would be east-west (E-W) oriented, with a gothic-shaped roof and double-glazing of PMMA (Polymethylmethacrylate) covering. Natural ventilation reduced the inside temperature of greenhouse, thereby reducing the energy demand of cooling. The model developed can help greenhouse farmers and researchers make pre-design decisions regarding greenhouse construction, taking their local environment and specific needs into consideration.

“…The load for the SING interconnected power system was assumed to be a constant 2 GW. An average daily profile with hourly loads in the range of 4 GW to 5.3 GW, reported by Watts and Jara [21] was used for SIC. We calculated PV capacities and associated energy penetration in the two grids for the PV systems in four plane configurations: fixed horizontal, fixed north facing at latitude tilt, one-axis tracking with the rotational axis at zero degrees, and one-axis tracking with the rotational axis at 20 degrees S-N; both one-axis systems were modeled after First Solar's 5 kW tracker with rotational limits of ± 45 degrees.…”

New markets for photovoltaics are being created in emerging economies where rich solar resources can produce solar electricity at affordable costs. A case in point is Chile, a country with great solar resources planning renewable energy deployment to address the needs of an expanding mining industry and a growing economy, while preserving the environment. The expansion of metal mining and smelting operations is constrained by the cost of electricity and the unavailability of water in northern Chile, offering an opportune synergy between photovoltaics and mining. Local estimates put the potential for solar electricity in the north interconnect at more than 200 GW, those of geothermal in the north and central interconnects from 3-16 GW, wind in the central interconnect from 5-40 GW, and small hydro and biomass in the south at 0.3 and 0.4 GW, correspondingly. These resources can supply not only the needs for sustainable development in Chile but can also produce electricity for neighboring countries. This paper examines the potential for immediate PV penetration in Chile's main electricity grids (SING and SIC) and options (i.e., curtailment, PV and wind combinations) that can increase such penetration.

“…According to Dutra & Tolmasquim (2000), wind generation projects should be treated as case studies and, coincidentally, most of the works found are characterized as these ones. Some examples in Latin America are Watts & Jara (2011), Melo (2012 and Salles (2004). The accuracy of the information used in this type of analysis is greater, but these are more limited.…”

Resumo: O mundo está vivenciando uma profunda mudança climática, causada pela atividade predatória do homem, tendo em vista que as atividades econômicas foram exercidas sem preocupação com os impactos Palavras-chave: Energia eólica; Viabilidade econômico-financeira; Taxa Interna de Retorno. Abstract:The world is experiencing a deep climate change caused by the predatory activity of man, due to the long time economic activities practiced without concerns on the environmental impacts. However, nowadays there is the necessity to expand the current economy without compromising the necessary resources for the survival of the future generations. The intensive use of alternative energy configures a contribution to this new development path. In another perspective, the main technical analysis of economic and financial feasibility is widely known; however, the application of techniques that consider the risk is not so usual. Thus, this current work addresses whether it is possible to identify the economic feasibility of a potential wind power generation plant in different Brazilian locations considering the risk of applying Monte Carlo simulation and Beta distribution techniques. In order to answer this question tests were performed in four different locations in Brazil, utilizing the Internal Rate of Return (IRR) method with the mentioned techniques to consider the risk in investment analysis. The results showed the sensitivity of the wind project to the financing costs, regardless the region studied.
