This paper mainly focuses on the two issues through remote sensing: assessment of the renewable energy potential and integration of the renewable energy model. Three methods for assessing the renewable energy potential with remote sensing (RS) are proposed. The methods can provide more precise evaluation of renewable energy potential, which is the first vital step to develop renewable energy model. The paper then first presents three integrations of the renewable energy model with RS and points out that with respect to the problems one of them is employed. The assessment methods based on RS and the integrations with RS are illustrated by a simple example with Europe solar energy data set. The results show that Germany is the optimal country to install photovoltaic with a capacity of 137 125 GW. Copyright © 2009 John Wiley & Sons, Ltd. 相似文献

In June 2004, the Prime Minister of Australia, John Howard, released the long-awaited government blueprint for the favoured policy direction for the country's energy sector, Securing Australia's Energy Future. In part this document was a response to a review of the operation of Australia's mandatory renewable energy target (MRET), a regime that started in April 2001. MRET was put under detailed scrutiny from March 2003 onwards by a four-person panel (the Tambling Committee), appointed by the Howard coalition (conservative) government, that received 248 detailed submissions and finally released its findings to the public in January 2004. This paper presents an overview of (i) the range of opinions on MRET presented to the Tambling Inquiry; (ii) the recommendations of that Committee; (iii) the final judgement on MRET enunciated in Securing Australia's Energy Future; and (iv) the response of the States. 相似文献

在我国建筑能耗总量和耗能比重不断攀升的背景下,能源危机日益加剧。把太阳能、风能和地热能等可再生能源应用到建筑节能中,是解决建筑能源问题的重大抉择。由于建筑物外围护结构直接和外界接触,是室内热量散失的主要途径,讨论了节约能源的保温绝热策略。阐述了被动式太阳能利用、主动式太阳能利用、太阳能光电技术、风力发电、自然通风和地热利用的基本原理,对于每一种利用方式,从应用实际出发提出了具体的建筑节能策略。 相似文献

分布式电源从属于不同运营部门,相互之间缺乏有效的信息交换,难以进行集中控制。文章针对可再生能源电网中由于新能源占比较高,易出现出力波动或出力不足,难以保障供能可靠性等问题,提出一种基于信息物理融合的可再生能源电网分布式能量控制模型。首先,为进一步提高可再生能源电网能量平衡控制能力,建立了可再生能源电网信息物理模型;然后,考虑可再生能源波动性对系统的干扰,建立一种自适应滑模观测器对可再生能源电网的扰动进行估计;最后,提出一种基于可再生能源电网的分布式协同控制器,并基于李雅普诺夫稳定性理论验证了该控制器的收敛性。仿真结果表明,文章所提出的控制方法可以提高可再生能源电网的能源利用率,增强系统的鲁棒性。 相似文献

Urban form, i.e., the layout, density, shape and orientation of buildings within the street grid of a city, affects greatly the potential of using renewable energy sources such as sun and wind for electricity production and climatisation of buildings. This paper outlines the framework of the European research Project PRECis (assessing the Potential for Renewable Energy in Cities) and, in particular, the role of the Polytechnic University of Turin in that Project. 相似文献

Finland was an early adopter of several alternative energy technologies, particularly in biomass and hydropower energy for many years. The main policy in the Finnish energy and climate sectors is to increase the exploitation of renewable energy sources while reducing CO2 emissions. Meanwhile, a successful energy policy should achieve three conflicting objectives: clean, cheap, and secure energy. The development of renewables in Finland has lagged that of other EU countries, particularly in fields such as wind power in recent years. This article discusses about the history, current status, and potentials of the major renewable and local energy in order of utilisation in Finland. It is seen that the major contributors to replacing carbon-based fuels are likely to be biomass and wind power, with geothermal and solar energy sources to play a lesser role. 相似文献

There are regions in the Republic of Croatia (underdeveloped, devastated by war, depopulated, as well as islands and mountainous areas) which are still disconnected from the electricity network or where the current network capacity is insufficient. In addition, these regions have good renewable energy potential. Since the decentralized energy generation (DEG) covers a broad range of technologies, including many renewable energy technologies (RET) that provide small-scale power at sites close to the users, this concept could be of interest for these locations. This paper identifies the areas in Croatia where such systems could be applied. Consideration is given to geographical locations as well as possible applications. Wind, hydro, solar photovoltaic, geothermal, and biomass conversion systems were analyzed from a technological and economic point of view. Since the renewable energy sources (RES) data for Croatia are rather scarce, the intention was to give a survey of the present situation and an estimate of future potential for DEG based on RES. The energy potential (given as capacity and energy capability) and production costs were calculated on a regional basis and per type of RET. Finally, the RES cost–supply curves for 2006 and 2010 are given. 相似文献

Marine renewable energies are promising enablers of a cleaner energy future. Some technologies, like wind, are maturing and have already achieved commercial success. Similar to their terrestrial counterparts, marine renewable energy systems require energy storage capabilities to achieve the flexibility of the 21st century grid demand. The unique difficulties imposed by a harsh marine environment challenge the unencumbered rise of marine renewable energy generation and storage systems. In this study, the fundamentals of marine renewable energy generation technologies are briefed. A comprehensive review and comparison of state‐of‐the‐art novel marine renewable energy storage technologies, including pumped hydro storage (PHS), compressed air energy storage (CAES), battery energy storage (BES), hydrogen energy storage (HES), gravity energy storage (GES), and buoyancy energy storage (ByES), are conducted. The pros and cons, and potential applications, of various marine renewable energy storage technologies are also compiled. Finally, several future trends of marine renewable energy storage technologies are connoted. 相似文献
