由于传统DCF分析方法不能完全满足可再生能源发电项目投资决策的需要,本文提出了在可再生能源发电项目投资决策中引入实物期权的思路,初步讨论了可再生能源发电项目投资的实物期权模型,并以风力发电项目投资为例具体讨论了实物期权模型的应用方法. 相似文献

能源危机、环境污染和全球变暖使世界各国普遍认识到可再生能源发电的必要性。从系统科学的思维角度和理论出发,通过文献调查和专家访谈,挖掘出影响我国区域可再生能源发电项目开发的12个关键因素,运用改进解释结构模型分析关键影响因素间的层级递阶结构关系。在此基础上,运用交叉影响矩阵相乘法模拟关键影响因素的驱动力——依赖性分布。结果表明:区域经济和城市化发展、政府激励政策对区域可再生能源发电项目开发的驱动力最强,同时也是最根本的影响因素。 相似文献

Renewable energy resources have historically played a small role for electricity generation in the US. However, concerns such as security of energy supply, limitations and price fluctuations of fossil fuels, and threats of climate changes have encouraged US policy makers to think and debate about diversification strategy in the energy supply and promotion of renewables. The current paper discusses the role of renewable portfolio in the US energy action plan during 2010–2030. A system dynamics model is constructed to evaluate different costs of renewable energy utilization by 2030. Results show that while renewables will create a market with near 10 billion $ worth (in the costs level) in 2030, the total value of renewable energy promotion and utilization in the US will be more than 170 billion $(in the costs level) during 2010–2030. 相似文献

This comparative study evaluates an investment project on renewable energy based on wind power. We have conducted the study in three European Union countries: Denmark, Finland and Portugal. We have modelled the main uncertainties that affect this kind of project, such as the cost and production of electric power, investment costs and consumer price index. For each of these countries, we have analysed the mechanisms of public support for wind energy. We have identified the real options included in the regulatory frameworks of these three countries and assessed how they affect the expanded net present value of the project. To this end, we have used two different methods of option valuation: the Monte Carlo method and the binomial method. We have proved that the obtained results using both methods are quite similar. Finally, we have evaluated the public incentives for wind energy offered in each of these three countries and concluded that, in economic terms, Finland is the country with the strongest support for this kind of energy, followed by Denmark and, in the last place, Portugal. 相似文献

在深入调研的基础上,针对可再生能源发电项目规划环节面临的开发排序问题及运行后的效率综合评估问题,建立了聚类分析和数据包络分析相结合的CA/DEA两阶段评价模型。基于文中所设计的综合评价指标体系,引入了模糊层次分析法对于环境协调度等定性指标进行了综合分析,并运用基于聚类分析的主导因素挖掘方法从众多指标中选出最具影响力的因素指标;采用非参数DEA最优化模型对发电项目综合效率进行评估,较好地解决了生产函数难以确定的问题。通过CA/DEA模型所确定的综合投入产出效率,实现了对发电项目优秀度的有效评价。最后通过实例分析,验证了该评估方法的有效性及实用性。 相似文献

Mexico is not reaching its full potential to capture benefits from clean development mechanism (CDM) projects because of its limited market for independent power producers (IPPs) and the barriers imposed on these entities by the state-run electric utility that controls most of the country's generation and transmission. This state-run entity has pursued CDM revenues only in isolated cases where international financial assistance was given because it is bound by law to pursue the least-cost generation option for its customers. Recent changes in Mexican legislation that provide incentives for renewable energy development could open the marketplace for these types of projects. 相似文献

Utilization of non-renewable energy sources not only results in environmental deterioration but also confronts us with the dilemma of a rapid rate of depletion of such resources, while renewable energy sources can serve us indefinitely with minimal environmental impacts as compared with fossil and nuclear fuels.This article deals with the extent of harnessing renewable energy sources for power generation in Iran, a Middle Eastern Asian nation. 相似文献

Any of several business structures may be used to operate a farm enterprise. Models have been developed showing advantages and disadvantages of sole proprietorships, partnerships, and corporations when applied as farm enterprises. In recent years, the farm cooperative business structure has taken on a different complexion, especially when faced with new crops and uses, mixed, multiple, and international markets, and cross-cutting market sectors. These new generation cooperatives have played a particularly strong role in developing renewable energy and agricultural enterprises, especially in the face of proposed new crop rotations, inclusion of perennial crops in these rotations, and different management scenarios based on agro-forestry principles. In this paper, we define conditions under which the farm cooperative is an appropriate business enterprise structure, and review and update the status of four of these new generation cooperative business structures in Minnesota, New York, and Iowa. We assess the status of development of these cooperatives and the market conditions needed for the agriculture, energy, and environmental sectors that comprise these cooperatives. 相似文献

North African countries generally have strategic demands for energy transformation and sustainable development. Renewable energy development is important to achieve this goal. Considering three typical types of renewable energies— wind, photovoltaic (PV), and concentrating solar power (CSP)—an optimal planning model is established to minimize construction costs and power curtailment losses. The levelized cost of electricity is used as an index for assessing economic feasibility. In this study, wind and PV, wind / PV / CSP, and transnational interconnection modes are designed for Morocco, Egypt, and Tunisia. The installed capacities of renewable energy power generation are planned through the time sequence production simulation method for each country. The results show that renewable energy combined with power generation, including the CSP mode, can improve reliability of the power supply and reduce the power curtailment rate. The transnational interconnection mode can help realize mutual benefits of renewable energy power, while the apportionment of electricity prices and trading mechanisms are very important and are related to economic feasibility; thus, this mode is important for the future development of renewable energy in North Africa. 相似文献

2000年4月,德国可再生能源法(EEG)代替了1991年生效的电力供应法(StrEG)。新颁布的可再生能源法,调整了各种可再生能源发电的补偿标准。其中对风力发电在装备投产使用后的不同时期规定了不同的补偿标准。即初期阶段较高的补偿标准,和后续期较低的补偿标准。因为风电的补偿与风机安装地点风力资源的多少,即与风机安装地点的质量有关,因此,为了使补偿值的确定更为合理,在可再生能源法中引入了。推荐 相似文献
