藏东南水电基地电力外送市场初探

本文通过对藏东南水电基地电力外送市场的选择,影响藏电外送的主要因素、外送规模、外送的技术经济可行性进行分析后认为:目标市场对藏东南水电的外送不产生根本制约,各主要目标电力市场接受西藏外送水电的市场空间会逐年增大。目前藏东南水电外送仍然受到包括跨区输电走廊建设、输电方式和电力供需、水电开发时序等多种因素制约。随着外送规模的扩大,藏东南水电基地的接续作用将逐渐显现。从技术和经济发展来看,尽管存在种种障碍,但未来藏东南水电基地电力的外送仍具有技术经济的可行性。

Hydropower's future,the environment,and global electricity systems

Hydropower is a well established electricity system on the global scene. Global electricity needs by far exceed the amount of electricity that hydrosystems can provide to meet global electricity needs. Much of the world's hydropower remains to be brought into production. Improved technology, better calibrated environmental parameters for large projects have become the norm in the past 15 years. How and why does hydropower retain a prominent role in electricity production? How and why does hydropower find social acceptance in diverse social systems? How does hydropower project planning address issues beyond electricity generation? How does the systems approach to hydropower installations further analysis of comparative energy sources powering electricity systems? Attention to the environmental impact of hydropower facilities forms an integral part of systems analysis. Similarly, the technical, political and economic variables call for balanced analysis to identify the viability status of hydro projects. Economic competition among energy systems requires in context assessments as these shape decision making in planning of hydropower systems. Moreover, technological change has to be given a time frame during which the sector advances in productivity and share in expanding electricity generation. The low production costs per kWh assure hydropower at this juncture, 2009, a very viable future.

水电开发与资本运作系统的耦合风险

我国水电资源丰富,水电类上市公司很大程度上支撑着我国的能源供给。水电开发与资本运作两大系统是其中的两大板块,两者耦合对风险的影响不容忽视。对水电开发市场、资本运作市场以及合并市场的GARCH模型的实证检验表明,风险具有持续性,且耦合风险有所降低。因此,能源企业可通过资本运作来应对冲实体经济的风险,可在一定程度上减轻能源企业在实体经济上所受的损失。研究成果可为能源类上市公司的资本运作提供参考。     

Assessment of small hydropower potential using remote sensing data for sustainable development in India

India being a developing country has witnessed a rapidly growing energy needs owing to fast industrialization. Sustainable and qualitative growth for developing economics and habitat requires increased energy input from various resources while maintaining balance in the ecosystem during exploitation. Paper discusses state of the resource potentials, achievements and various issues related to the power generation in India. The growing concern over environmental degradation caused by fossil fuel based systems, opposition to large hydropower projects on grounds of displacement of land and population, environmental problems with nuclear fuel based systems and the ever-rising shortage of power highlights the need for tapping alternate energy sources for power generation. Amongst the alternate sources utilization of hydropower on a smaller scale (small, mini and micro hydropower) has become the thrust area for sustainable growth in the power sector. Hydropower is an economical and environmentally clean source of renewable energy abundantly available in hilly regions of India. Hydropower stations have an inherent ability for instantaneous starting, stopping, load variations, etc., and help in improving the reliability of power system.Huge hydropower potential in India, yet to be explored is located at inaccessible mountainous region. However, development of this potential is challenging due to difficult and inaccessible terrain profile. Paper presents application of remote sensing data for identification and selection of probable site for hydropower projects. The algorithm for identification and assessment of water resources and its perennial is developed in Visual Basic (VB) platform and it is successfully applied for IRS-1D, LISS III Geo-coded False Color Composite (FCC) satellite image for plain as well as hilly and mountainous regions. Classification of satellite image in to different objects is modeled as the task of clustering based on the intensity of R-G-B values of pixels. Results obtained are presented and compared with the Survey of India Toposheets (53K/2, 53K/3 and 53J/16). Use of Remote sensing data provides a scientific method of hydropower identification and assessment.

Hydropower–water and renewable energy in Turkey: Sources and policy

Turkey's energy consumption has been growing much faster than its production. It forces Turkey to make a rapid action to supply energy demand. From the viewpoint of primary energy sources (petroleum and natural gas), Turkey is not a rich country, but it has an abundant hydropower potential to be used for generation of electricity. Hydropower is the most important kind of renewable, sustainable energy and a proven technology for electricity generation. The aim of this paper is to discuss sources and policy of hydropower, water and renewable energy in Turkey and compares the hydropower application with Europe.     

Introducing MOZLEAP: An integrated long-run scenario model of the emerging energy sector of Mozambique

Since recently Mozambique is actively developing its large reserves of coal, natural gas and hydropower. Against this background, we present the first integrated long-run scenario model of the Mozambican energy sector. Our model, which we name MOZLEAP, is calibrated on the basis of recently developed local energy statistics, demographic and urbanization trends as well as cross-country based GDP elasticities for biomass consumption, sector structure, vehicle ownership and energy intensity. We develop four scenarios to evaluate the impact of the anticipated surge in natural resources exploration on aggregate trends in energy supply and demand, the energy infrastructure and economic growth in Mozambique. Our analysis shows that until 2030, primary energy production is likely to increase at least six-fold, and probably much more. This is roughly 10 times the expected increase in energy demand; most of the increase in energy production is destined for export. As a result, Mozambique may well become one of the leading global producers of natural gas and coal. We discuss the opportunities and challenges that this resource wealth poses for the country.     

西藏水电开发是应对治理揠塞湖的重要举措

西藏区域地质构造发育,又属于高震区,在局部强降雨强降雪等恶劣小气候条件下,自然灾害频发,在高山深谷的江河上尤其容易发生堰塞湖。2018年10月17日凌晨5:00左右,西藏林芝加拉村下游约6km处(大峡谷核心区、无人区)雅鲁藏布江(以下简称“雅江”)左岸发生大规模泥石流,造成干流断流,形成影响很大的雅江加拉村堰塞湖。堰塞湖的治理一直是个世界难题,本文从2018年10月17日治理分析加拉堰塞湖的实践,阐述从水电开发角度,在灾害区上游建设高坝大库拦水调蓄,水库下游再采取截弯取直方式引走来水,作为防治雅江大峡谷河段今后可能出现大型堰塞湖重要治理手段,防止大型堰塞湖造成水淹城乡和溃堰水淹下游灾难的发生,从而达到既推进雅江水电开发,又较好治理了大峡谷河段自然灾害,实现把水电开发建成“功在当代,利在千秋”的减灾防灾工程。

An estimation of the Swiss hydropower rent

The electricity generation in Switzerland is mostly based on hydropower (∼58%) and nuclear power (∼38%). The exploitation of water in the hydropower sector can generate significant economic rent. One possibility to capture this rent is through royalties or fees. This system has been used in Switzerland since many decades. However, the actual water fee system is not flexible and does not take into consideration different production costs between the type and location of hydropower plants. Furthermore, storage plants can sell electricity to a higher price than run-of-river plants. A flexible system is needed in a liberalized electricity market, to take into account these different production situations and the fact that prices may vary considerably over time. The main goal of this paper is to calculate the potential economic rent that could be generated in the Swiss hydropower sector under a future liberalized market. Based on the results of the paper, it can be concluded that the introduction of a flexible fee system could improve the competitiveness of the hydropower sector and promote an energy system based on renewable energy sources.
