Grid stability is being challenged by the increasing integration of power plants with volatile power generation into the energy system. Power supply fluctuations must be compensated by energy system flexibility. The storability of the energy carrier enables biogas plants to generate power flexibly. In this study, the technical and economic effects of providing positive secondary control energy reserves with an Austrian biogas plant were assessed. The plant’s main focus lies in biomethane production with the option of heat and power generation through combined heat and power (CHP) units. A detailed simulation model of the investigated biogas plant was developed, which is presented in this work. Ex-post simulations of one year of flexible plant operation were conducted with this model. The findings show that the installed biogas storage capacity is sufficient to provide control energy reserves while simultaneously producing biomethane. Profitability of providing control energy reserves largely depends on the prices at the control energy market and on CHP unit start-up costs. A cost efficiency analysis demonstrated that investing in a hot water tank with a volume of 5 m3 for short-term heat storage turned out to be economically viable.

Deep underground energy storage is the use of deep underground spaces for large-scale energy storage, which is an important way to provide a stable supply of clean energy, enable a strategic petroleum reserve, and promote the peak shaving of natural gas. Rock salt formations are ideal geological media for large-scale energy storage, and China is rich in salt rock resources and has a major shortage of energy storage space. Compared with the salt domes in other countries, the salt rock formations in China are typical lacustrine bedded salt rocks characterized by thin beds, high impurity content, and many interlayers. The development of large-scale energy storage in such salt formations presents scientific and technical challenges, including: ① developing a multiscale progressive failure and characterization method for the rock mass around an energy storage cavern, considering the effects of multifield and multiphase coupling; ② understanding the leakage evolution of large-scale deep underground energy storage caverns; ③ understanding the long-term performance evolution of large-scale deep underground energy storage caverns; ④ developing intelligent construction technologies for the deep underground salt caverns used for energy storage; and ⑤ ensuring the long-term function of deep underground energy storage spaces. The solution to these key scientific and technological problems lies in establishing a theoretical and technical foundation for the development of large-scale deep underground energy storage in China.

以“功能”储备补足“资源”储备——甲醇战略储备替代1/10~1/5的石油战略储备

对世界所有大国而言,石油战略储备是十分重要的。为了满足国家安全的需要,世界不同国际组织如联合国、欧盟等都建议设立3个月的石油战略储备。对于中国而言,这就需要战略储备石油3×107~9×107 t,这需要一个长时间段和大量资金注入才能完成。如果基于“功能”储备补足“资源”储备的一个新理念来思考,这一目标可以较容易地完成。即储备一定百分数的甲醇来替代石油,则国家安全也可以得到保障。

天然气水合物是甲烷等烃类气体与水在高压低温条件下形成的笼形化合物,俗称可燃冰,将有望成为继页岩气、致密气、煤层气、油砂等之后的储量最为巨大的接替能源,主要分布在北极冻土带和沿海大陆架300~3000 m水深的深水区,初步估计其资源量为全球含碳化合物的两倍,其中约95 %储存在深海区域;与此同时,深水浅层弱胶结水合物的无序分解等潜在工程地质灾害、温室效应等也已引起世界各国的高度重视,因此,天然气水合物资源安全高效开发和环境风险并重,成为当前世界科技创新的前沿。本文回顾了国内外天然气水合物资源勘探和试采技术研究进展,在此基础上,针对我国海域潜在目标区以及我国已经获取的天然气水合物样品的相关特性,提出了我国天然气水合物资源勘探开发技术方向。

以最小阻力定律、体积不变条件和秒流量相等条件为内容的经典轧制理论,经试验、演绎形成了较完整的轧制应用技术科学体系,这种体系所反映的是静态规律。在轧制理论发展中引入控制论、信息论、计算机科学等高新技术,对轧制过程进行控制。在轧制理论发展史上,弹跳方程建立之前是以力学为基础建立的经典轧制理论,之后为以力学和控制论为基础建立的基本轧制工艺控制理论。文章提出工艺控制理论概念,是在基本轧制工艺控制理论的基础上建立的新的理论体系,主要内容包括:在连轧张力理论中反映了张力的负反馈,建立了连轧张力理论体系;在厚控过程中,解决扰动的检测问题;在板形理论中,定义了对偶参数,确立了与 厚控理论相似的板形理论体系。
