近期,由于海上风电上网电价政策的出台引起了新一轮关于海上风电的探讨。根据风电发展“十二五”规划。我国海上风电装机容量2015年将达到500万千瓦,2020年将达到3000万千瓦。而至今我国累计已建成的海上风电项目仅42.86万千瓦,与“十二五”规划目标相距甚远。那么,开发海上风电究竟难在哪里?采用什么样的发展模式更适合我国国情?为了促进海上风电的健康发展。政府、行业、企业应做出怎样的努力?中国能源网首席信息官韩晓平先生长期致力于新能源的研究、开发和应用,对此有着深刻、独到的见解。 相似文献

The dena grid study II examines the integration of renewable energies into Germany??s electricity supply up to the year 2020 and gives a qualified outlook up to 2025. The study develops geographically differentiated scenarios for installed wind power capacity, on the basis of which time series of the wind power feed-in into high and extra high voltage nodes and offshore wind farms are generated. Future requirements for the transmission grid and grid extension options are analysed. Opportunities to introduce more flexibility in the power system in terms of supply and demand are examined. The study gives a conceptual perspective of the need for grid extension in inner Germany in order to fully integrate renewable energies, whilst operating power stations at optimum cost and exchanging electricity with other countries in response to market demands within the scope of the specified transmission capacities. 相似文献

Wind power takes a leading role among the renewable energy sources. Whereas in offshore wind power utilization large technical challenges still need to be tackled for commercial exploitation, the replacement of obsolete plants (repowering) in the onshore sector provides an interesting alternative. This paper first provides an overview of the technical, legal and social development concerning wind power utilization in general, and repowering in particular, in Germany. In a next step, by means of model-based analysis, the technical potential for wind power by means of repowering is determined. The theoretical potential is valuated against social aspects. Due to the large heterogeneity of candidate sites for repowering, general potential studies are not suitable for concrete investment decisions. Instead, a detailed economic feasibility study is required. In our study, we performed scenario analysis, also taking into account the repowering-specific risks. The parameter values varied are those for the quality of the site, the size of the wind park, and the age of the wind turbines to be replaced. Finally, we discuss the results and provide an outlook on the development of repowering in light of the novelized EEG. We find that, until now, the repowering potential could not be fully exploited. An intensified realization of repowering projects in the coming years can be expected, due to the technical potential, simplifications in the commissioning process, rising acceptance on the side of the communities due to changes in the tax legislation and, above all, thanks to the incentives for almost all onshore wind parks. 相似文献

In this paper we provide an overview of the various terms and methods used in risk management and risk controlling. Further, we identify and discuss internal and external risks of offshore wind power plants (WPP) and demonstrate for the concrete example of a fictitious 400 MW offshore wind park in the North Sea the use of the discounted cash flow (DCF) method. The offshore risks involved are considered as part of the different components of the free cash flow, which form the basis for the DCF evaluation, by using a Monte Carlo simulation. The latter contains assumptions for the distribution of each cash flow component, which are based on a detailed consideration of the risk bearings. We use the cash flow at risk (CFaR), with the DCF as the risk-carrying target variable, as a quantitative risk measure for the simulated DCF evaluation. The CFaR enables us to draw a conclusion regarding the risk distribution of the DCF. According to the fictitious offshore wind park studied, the CFaR obtained provides evidence that the investment project investigated is indeed economically viable. 相似文献

In Germany heat dissipation of subsea cables for power transmission from offshore wind farms into the sea floor is regulated. The precautionary value to be adhered to is a maximum temperature increase of 2?K in 20 to 30?cm sea bed depth. Such a temperature increase is defined by a number of influencing factors and boundary conditions and is extremely difficult to physically measure. Thus the purpose of this paper is to simulate the heat generation of DC submarine cables and the dissipation into the surrounding sea floor using the Finite Element Method (FEM). Herewith crucial parameters and influencing factors can be identified. The results show that the strongest influencing factors on the sediment temperature in 20 to 30?cm sea floor depth are the average load or longer-term preload of the cable, the burial depth and the thermal resistance of the sediment. Overall, during standard operation of wind farms and the corresponding cable systems the 2?K limit is adhered to safely. In general, this also applies to special wind and load situations. 相似文献

技术创新是解决目前风电产业产能过剩、缺乏核心技术发展瓶颈的重要路径,最新文献已经发现高管特征和企业异质性对企业技术创新绩效的影响,但研究结论尚存在分歧。本文以沪深两市风电产业上市公司为研究对象进行实证研究发现:高管持股和女性高管对风电企业技术创新绩效具有显著的促进作用;国有风电企业和省会城市风电企业的技术创新优势会因内部治理结构短板而丧失。将企业异质性作为调节变量进一步研究发现,国有企业中高管持股和女性高管对风电企业技术创新绩效的正向影响更加显著;区位在省会企业中高管持股和女性高管对风电企业技术创新绩效的正向影响更加显著。 相似文献
