Impact of renewable energies on the operation and economicsituation of coal fired power stations： Actual situation of coalfired power stations in Germany

引用

Frontiers in Energy 2017年第2期11卷 119-125页

作者： Hans-Joachim KRAUTZ Alexander LISK Joachim posselt Christian KATZER Department for Power Plant Technology Brandenburg University of Technology Cottbus-Senftenberg 03046 Cottbus Gemany

Due to the fluctuating character of the renewable energy sources the demand of conventional power plants for flexibility is increasing. In the recent years, in Germany there has been a fast rise of production capacity of renewable energies, especially from wind turbines, photovoltaic installations, and biomass plants. The installed nominal power of wind turbines is actually (December 2016) 42 GW and of photovoltaic installations 40?GW. The renewable electric energy production in Germany is about 190?TWh/a, which represents a share of 33% of the yearly demand. The increased need for flexibility affects both the power gradients as well as the minimum load of conventional power plants. Due to this flexibility behaviour, conventional power plants are faced with problems concerning the durability of power plant components, corrosion, more maintenance effort and consequently the overall life expectancy. Another consequence of the increasing share of renewable energies is the decreasing full load operating hours, especially of coal fired and gas power plants. Along with decreasing revenues from the energy exchange market, coal fired power plants are faced with new economically challenges.

单一的白光LED难以满足色彩与照明的应用需求．可调LED将是更好的选择随着固态照明技术的性能与效率不断超越传统照明技术，该新技术得到了广泛应用。不过，如果我们只是用静态白光LED来取代传统技术的话，就难以真正发挥固态照明技术的全部潜力，不能充分实现产品的特色化。在智能驱动器支持下，LED照明灯具不仅能取代白光照明，而且还能实现新的功能，而这些功能用传统的照明技术是很难实现的。

前言微量镉对人体健康的影响已得到充分证明。同其较丰富的邻近元素锌相反,镉被认为是对人体非主要元素,而且在人体组织中出现被当作是不正常的。在文献中有足够的事实断言,镉在生物机体中会蓄积,并且同主要元素锌在某些旦白质络合物中争夺结合位。由于其可能的毒性和较长的生物半衰期,故提出向环境中排放镉应尽可能地加以控制。
