Solar photovoltaic application of thermal power plant is not big, small thermal power plant or more market competitiveness?

The article content is for reference only. photovoltaic (pv) net news: as the only a kind of adjustable renewable energy power generation technology, solar-thermal power generation technology is thought to have great potential for development, but the high cost of power generation turned off many investors, and drastically limit the widespread deployment of the technology. , he said, than through technological innovation to achieve cost reduction, by narrowing the construction scale to make solar-thermal power generation technology & other; It is easier to do & throughout; Perhaps is more effective way to promote the development of this technology is rapid. How, for example, chest back fixed Ivanpah solar-thermal power stations in California 2 and 3 single machine installed capacity up to 133 mw unit. Now many of the tower is a big power station of installed in order to realize scale economic benefit. Specifically, CGNPC in development of 410 mw, 603 mw, guangzhou energy saving 220 mw, 345 mw, jin can group the people vote for 200 mw, 190 mw hubei energy group, huaneng 180 mwcrespo said that the modular & other; More tower & throughout; Design power efficiency can be increased by 25%. He said, & other; If the solar-thermal power generation costs can drop to $60 / MWh, solar panels, so it will have considerable market competitiveness, I believe that the solar-thermal power generation cost can even further, but we must start to adjust. Large scale has been considered as one of effective way to reduce cost of solar-thermal power stations, however, the Spanish solar-thermal power association ( Protermosolar） , chairman of the European association for solar thermal power generation ( ESTELA） Former President Luis Crespo has recently put forward the opposite view. Some plants have towards this trend. Designed to ensure that solar-thermal power could supply power at any time or season, and realize the DOE set in thermal power plant (2030 years ago The thermal storage time & ge; 12 hours) Cost down to 5 cents/kWh. Crespo was also highlighted as far as possible in the peak time of electricity power generation benefits, this will allow the same power generation benefit under the solar-thermal power plant size smaller. Configuration of energy storage tower solar-thermal power projects and photovoltaic or wind power project cost gap between has become very big. In the United States, for example, recently the us department of energy ( DOE） 13 projects for a total of about $30 million of announced financial support, can significantly reduce manufacturing costs to research including new materials and technologies, and new sources of energy storage technology, and development can make the sun island realize full automatic operation of the solution. ” photovoltaic (pv) network statement: this information is reproduced from the media or other Internet web site, network cooperation photovoltaic network published the article for the purpose of the information, does not mean that agree with his point of view or confirm its description. This paper statistics the September to today issued a total of 2. 85 gw pv power plant EPC and 1. 9 gw component bid opening information.

thanks to the rise of China enters a new market, such as, how much is the solar panels a solar-thermal power generation cost has dropped in 2018. Technology innovation is in progress. Although has the function of heat accumulation than the independent photovoltaic solar-thermal power generation project has higher operating value, but & other; Wait on electricity market for its more cost in vain & throughout; 。 Crespo was expressed, freiburg solar energycity technology innovation is worth affirmation, solar equipment, but this kind of innovation within ten years or so at least not converted into cash. Crespo was in its recently published research report pointed out that two & other; Small adjustments & throughout; Or can improve the solar-thermal power generation technology in the global renewable energy market. Crespo and its research partners Francisco Ramos thinks, because of the power plant heat receiver and the distance between the lens field too far, that reflected light began to dissipate before reaching the target location, the overall efficiency of power plant will be affected. South Africa, for example, 100 mw of installed Ilanga 1 thermal power plant put into operation in November, solar energy, according to the power purchase agreement, 5 PM to 10 PM, the plant's electricity price premium rate is as high as 207%. One is plant development and operations should be as much as possible to achieve in the peak time of electricity price sell electricity. In order to overcome this problem, the project developer should establish multiple smaller mirror field, each field lens with central heat absorption tower. Instead, the industry now should focus on the optimization and upgrading of existing technology. , according to data from the latest analysis of new energy storage and heat power tower of the leveling of subsidies, energy cost is 126 - 156 / MWh, a utility scale solar photovoltaic (pv) or the cost of wind power project to a much higher. Secondly, the design of the polysilicon wafer price solar-thermal power tower from large to small, modular concept. A single & other; Tower & throughout; Should be in 30 - the standard of power 50 mw and & other; Sharing & throughout; A power of 500 mw power island. Among them, the EPC project owner units is given priority to with soe/state, China solar energypower network, this also reflected from the side, photovoltaic (pv) grid, in project bidding and parity, the state-owned enterprises have become the absolute main force. Tower power plant is one of the most mainstream solar-thermal power plant technology.
