西藏可再生能源详考

西藏自治区是我国的西南屏障，具有十分重要的战略地位。最近几年，随着改革开放的进一步深入和西部大开发的全面实施，西藏正在逐步加大对外开放的力度，以吸引更多的投资和建设项目。但是，由于西藏的地理条件和自然条件的限制，交通和电力等基础设施的相对落后，已经成为制约西藏发展的瓶颈。我国政府投入了大量的财力和物力发展可再生能源，现正在西部部分省份实施利用可再生能源发电解决无电乡镇的用电问题，即“光明工程”。其中西藏自治区是“光明工程”的重中之重。为了更为有效地在西藏自治区发展和利用太阳能，解决电网无法覆盖地…

户用光伏系统的应用及市场前景

太阳能光伏发电是国家重点提倡开发利用的绿色能源。广泛使用绿色能源对减少二氧化碳和其它有毒气体的排放,防治大气污染,保护生态环境具有重要意义,也是自然赋予人类和社会的历史责任。我国土地资源辽阔,人口居住分散,常规能源供应缺乏。为了满足经济发展对能源的需求,必须通过开发利用新能源和可再生能源加以补充。在我国西部,多数地区自然条件比较恶劣,经济落后,生活条件艰苦,迄今为止,该地区无电户总数达1000万户之多。为此,国家在该地区实施了“光明工程”,利用太阳能来解决当地的能源问题。随着太阳能光伏发电在人们生活中被逐步认识…

我国可再生能源发展面临的问题及新机制的建立

中国可再生能源发展面临发电成本高、市场容量小、制造业薄弱、缺少立法支持和相应的运行机制等多种问题。解决这些问题的途径首先是推动可再生能源立法,其次,在立法的基础上进行可再生能源发展机制的创新,建立包括目标机制、定价机制、选择机制、补偿机制、交易机制和管理与服务机制等在内的运行机制。由于中国发展可再生能源要实现多种目标,因此不能依靠单一手段解决所有的问题。中国可再生能源发展的新机制应该是多种机制共同起作用的系统。

Techno-economic viability of three different energy-supplying options for remote area electrification in India

Distributed power generation based on renewable energy sources brings new life and hope to electrify remote villagers. The proposed work suggests the techno-economic feasibility of three different energy-supplying alternatives namely the solar photovoltaic (SPV) system, diesel generator system and extending the grid connection for energy supply to a remote village located around 15 km away from the place where grid supply is available. Design of all the above three systems along with their economic analysis is carried out in this paper. A comparison on the basis of economic indicators like unit cost of electricity, net present value and payback period among the three systems is also discussed. The results show that the SPV system is economically more viable among the three options apart from environment benefits. This study may provide a new direction for energy planners to supply energy in remote non-electrified areas of India through SPV systems.     

Why are remote Western Australians installing renewable energy technologies in stand-alone power supply systems?

As people living in remote areas rely on SPS systems for their electricity and water needs, they hold a practical and non-idealistic perspective towards using renewable energy technologies. This research explores pastoral owner-operators’ personal experience and opinion of stand-alone power supply (SPS) systems over 30 years in remote pastoral regions Western Australia (WA). This research was undertaken qualitatively in terms of the experience of remote Australians of energy service delivery and SPS system performance to obtain personal opinions of remote pastoral people who rely on SPS systems to provide basic needs. This research concluded that the impressive growth in total renewable energy capacity in remote off-grid SPS systems in WA is primarily due to subsidies that aim to fuel-switch to renewable energy sources. Despite this, other major reasons for the increases in renewable energy capacity are escalating conventional fuel costs, difficulties in attracting qualified service contractors, increasing desire for quiet, 24-h energy services, and a range of unique situations. Despite the increased use of renewable energy technologies, this research reinforced previous research conclusions that consistently found both the conventional and renewable energy service sector wanting in remote areas. Three areas needing attention to sustain the growth in renewable capacity are: technical SPS system integration, service infrastructure, and technical reliability.     

Renewable energy policy and landscape management in Andalusia,Spain: The facts

Renewable energy has developed spectacularly in Spain since the European Union started a process of energy policy reform. A review of Spanish State legislation on renewable energies confirms that the success in installing renewable energy is attributable to public aid. Andalusia is one of the autonomous communities, which has simultaneously developed the legal framework and very successfully implemented the introduction of renewable power. When implementing the central government’s policy, the Andalusian regional government prioritised increases in both surface cover by wind and solar plants (thermal and photovoltaic energy) and in the number of companies involved. However, this development of renewable energies took place without any proper integration into regional spatial and landscape planning. This paper explores renewable power implementation in Andalusia through regulatory measures put in place over the last decade to develop renewable energy systems and the way they can be managed alongside planning issues. The location of large-scale renewable plants has had consequences for territory in the socio-political context of renewable energy promotion. The main findings focus on renewable energy plant sprawl throughout rural areas in Andalusia with no clear effect on landscape management and no firm backing from the local population.

Stable power supply of an independent power source for a remote island using a Hybrid Energy Storage System composed of electric and hydrogen energy storage systems

We propose a self-sustaining power supply system consisting of a “Hybrid Energy Storage System (HESS)” and renewable energy sources to ensure a stable supply of high-quality power in remote islands. The configuration of the self-sustaining power supply system that can utilize renewable energy sources effectively on remote islands where the installation area is limited is investigated. It is found that it is important to select renewable energy sources whose output power curve is close to the load curve to improve the efficiency of the system. The operation methods that can increase the cost-effectiveness of the self-sustaining power supply system are also investigated. It is clarified that it is important for increasing the cost effectiveness of the self-sustaining power supply system to operate the HESS with a smaller capacity of its components by setting upper limits on the output power of the renewable energy sources and cutting the infrequent generated power.     

Drivers,barriers, and strategies for implementation of renewable energy technologies in rural areas in Bangladesh—An innovation system analysis

Bangladesh has good potential for harnessing renewable energy sources such as solar, biomass, wind, and mini-hydropower. The country has been experiencing a gradual shift towards exploring renewable energy resources as a driving force for rural development. A few public sector and non-government organizations have started to develop renewable energy technology (RET) projects in rural areas. The lessons learnt from different demonstrations of RET projects reveal that with careful forward planning renewable energy can provide far-reaching economic, environmental, and social benefits to people living in remote rural areas in Bangladesh. This paper identifies some of the barriers that need to be overcome for the successful development of renewable energy technology sector and betterment of rural livelihoods. It does so through a critical review of policy and institutional settings, as well as present status and lessons learnt from pilot demonstration of a number of RET projects undertaken by different organizations. The study highlights policy implications of the review with the aim of supporting decision makers in formulating renewable energy policies and future plans for Bangladesh.
