可再生能源发电

可再生能源是指不会随人类的开发利用而衰减的能源,如风能、太阳能、生物质能、小水电（指设计能力低于２５兆瓦的工程）、海洋能、垃圾再利用能源、垃圾掩埋沼气、污水处理沼气、地热能等。我国的自然资源总量排世界第７位,能源资源总量居世界第３位。其中可再生能源资源尤其丰富,可开发风能资源２．５亿千瓦,水能资源７５４０万千瓦,生物质能１．２５亿千瓦,地热能６７０万千瓦,另外还有数量巨大的太阳能及城市垃圾利用潜力。１我国太阳能资源我国地处北半球欧亚大陆的东部,幅员辽阔,有着十分丰富的太阳能资源。我国各地的太阳辐…     

我国可再生能源发电问题的分析及对策

一、我国发展可再生能源发电的必要性 我国目前已拥有3亿千瓦的电力装机,国电公司全额投资、控股或参股的电厂占总装机的一半左右.全国发电量达到1.2万亿千瓦时.其中火力发电量占总发电量的74.5%,可再生能源发电不足1‰(未包括小水电).几力发电总装机容量34千瓦,风机国产化率可达40%以上;太阳能光伏发电总装机容量2万千瓦,9个国内生产厂家的年生产能力达1万千瓦.我国电力行业发展的传统模式是“大机组、大电网、高电压、集中供电”.今后很长一段时间内,我国电力行业还将继续沿着这样的模式发展.但是这种模式是否能解决我国的用电问题呢?

发电调度优先考虑可再生能源发电

近日，国家发展改革委等部门联合下发通知，要求发电调度中优先考虑可再生能源和低能耗机组发电。     

Renewable energy and its impact on thermal generation

Electricity production from renewable sources generally displaces thermal generation, which leads to lower CO₂ emissions in the power sector. However, the intermittent nature of many renewable technologies in combination with less residual demand leads to greater inefficiencies in the operation of existing fossil power plants. This inefficiency translates into a higher rate of emissions relative to output. In this paper we focus on Italian power installations between 2005 and 2014. Using panel econometrics, we show that a 10% increase in photovoltaics and wind infeed has reduced yearly CO₂ emissions of the average thermal installation by about 2% while the average plants emissions relative to its output have increased by about 0.3%.     

Communication on energy Renewable energy and environment policies in Africa

Energy policies in Africa, as in most other developing regions, have been in a state of flux ever since petroleum-based fuel prices began to rise significantly from late 1973. For African countries, the timing of this increase in energy prices could not have been at a worse juncture. In the early 1970s, many African countries — especially those in the Sudano-Sahelian region, had been ravaged by years of drought, which had seriously adverse impacts on food production. When energy crisis was superimposed on an already persistent food crisis on a group of developing countries whose economies were not robust and resilient enough to successfully withstand even one of such major crises, the results were predictable and catastrophic.     

Renewable energy resources,policies and gaps in BRICS countries and the global impact

This paper presents comparative yet extensive analysis of existing non-conventional renewable resources, energy policies and gaps in BRICS countries. An intelligent transformation to green economy to maintain natural resources is noted. Brazil has stable energy policies and is the leading producer of biofuels following hydropower until 2014 but supported wind and solar power development by tendering specific tariffs for energy generation from solar and wind. Russia needs improvement in its legal and regulatory framework with more incentives in energy policies. China is improving upon wind and hydropower but it needs strong policy measures to put cap on increased CO₂ emissions. India needs revision in energy policy and requires extra incentives and consumer specific energy policies for research-infrastructure and energy generation technologies. South Africa requires lessons to increase renewable energy and reduce coal mining. Moreover, BRICS countries need to redefine their energy policies based upon their existing geographical, economical, societal and environmental conditions which will help in shaping global energy policies and more financial stability. This paper recognizes the potential of BRICS to reshape the global system paralleled with minimizing CO₂ emissions. The concerted role of BRICS needs to be recognized as the leading contributor of global renewable capacity where the developed world is geared and busy to address the environmental issues.     

Renewable energy sources for clean and sustainable energy policies in Turkey

Energy is an essential factor to achieve sustainable development. So, countries striving to this end are seeking to reassess their energy systems with a view towards planning energy programmes and strategies in line with sustainable development goals and objectives. As would be expected, the rapid expansion of energy production and consumption has brought with it a wide range of environmental issues at the local, regional and global levels. States have played a leading role in protecting the environment by reducing emissions of greenhouse gases. Turkey is an energy importing country with more than half of the energy requirement being supplied by imports, and air pollution is becoming a great environmental concern in the country. On the other hand, Turkey's geographical location has several advantages for extensive use of most of the renewable energy sources. In this regard, renewable energy resources appear the most efficient and effective solutions for clean and sustainable energy development in Turkey. This paper provides an overview of global energy use and renewables for clean and sustainable energy policies in Turkey.     

On the impact of FIT policies on renewable energy investment: Based on the solar power support policies in China's power market

In 2013, the feed-in tariff (FIT) policy was issued in China to promote the investment in renewable technology, but then it was revised because this policy brought a heavy financial burden to the government. By considering the intermittence of renewable resources, we model the implemented Chinese FIT policies and analyze their impact on renewable energy investment in the power market. The open-loop model is employed to simulate the China's power market organized with Power Purchase Agreement, and the closed-loop game is used to characterize the spot power market. Meanwhile, the strategic capacity choices of power generators in two games are compared under four different policy schemes: (i) free competition, (ii) FIT via fixed subsidy, (iii) FIT via price premium and (iv) Chinese FIT by cross control (CFCC). The results show that the CFCC policy is a good alternative to well control the investment in renewable technology, as it can be seen as a comprise between free competition and FIT via fixed subsidy policy. Furthermore, compared with the other three policy schemes, the CFCC policy is capable of keeping renewable power generators from deviating the equilibrium, which implies higher robustness in regulating the electricity spot market.     

可再生能源电力呼唤智能电网

正当所有国人礼赞中国可再生能源电力发展成就的时候,风电、光伏发电等可再生能源电力的"含金量"却因受上网硬件的约束而陡然失色。据国家电监会最近公布的《风电、光伏发电情况监管报告》数据显示,2009年,我国已并网但未被收购的可再生能源电量达27.60亿千瓦时,未收购的电量主要来自风力发电,约占当年并网风力发电量的10%。2010年上半年,仅占全国发电装机容量2.46%的可再生能源电力中,仍有27.76亿千瓦时的风电被弃。     

Renewable energy resources for electricity generation in Sudan

Electricity reaches only about 30% of Sudan's more than 40 M population; this mainly in urban areas. Hence, a major problem for rural people is the inadequate supply of power for lighting, heating, cooking, cooling, water pumping, radio or TV communications and security services. Petroleum product supplies, including diesel, kerosene and LPG are irregular and often subject to sudden price increases. Because of the inadequate supply of these fuels, women trek great distances into the forest to collect fuelwood, charcoal and biomass residues from animal and agriculture, account for more than half of total energy consumption. Most of this is utilised for cooking and heating water in rural and semi urban areas and by the urban poor. It is a need to provide alternative renewable energy sources to enhance women's participation in, and benefit from development. Household energy was the first energy sector that paid explicit attention to women and their energy needs. The contribution of women to environmental policy is largely ignored. Decision-making and policy formulation at all environmental levels, i.e., conservation, protection and rehabilitation and environmental management are more or less a male preserve. Women have been involved in promotion of appropriate energy technologies, primarily for rural population over the past 15 years. This article highlights the experience of working with rural people in seeking solutions for community energy needs through renewable environmentally friendly energy technologies.     

New energy power generation-wind power generation

This paper introduced the status quo of wind power and wind power generation technology. Focusing on the introduction of wind power generating system ibrational self-consistent field（VSCF）, program implementation included Alternating Current （AC）-Direct Current （DC）-AC conversion system, magnetic field modulation generator system, doubly-fed generator system etc. Among these, doubly-fed generator system is the trend. Where to build the wind farm is very important, so a perfect site is needed. Wind power generation will have a bright future. As long as the wind power can be linked to the grid in large scale.
