【正文】 stem 湖北理工學(xué)院 畢業(yè)設(shè)計（論文 ） 外文文獻(xiàn)翻譯 10 A storage device grid photovoltaic power generation system: is in the above several kind of photovoltaic power generation system according to the need configuration energy storage device. With energy storage device of photovoltaic system initiative is stronger, when the power grid in power, power brownouts and fault, independent operation, the normal power supply to the load. So with a storage device grid photovoltaic power generation system can be used as emergency munication power supply, medical equipment, gas stations, shelter directives and lighting, and other important or emergency load of power supply system. advantage (1) the use of clean, renewable natural energy, solar power consumption nonrenewable resources, limited carbon fossil energy, the use of no greenhouse gases and pollutant emission, and ecological environment harmonious, in line with the economic and social sustainable development strategy. (2) the power can be fed into the grid to power grid for energy storage device, dispense with battery, than independent solar photovoltaic system construction investment can reduce 35% one 45%, so that the generating cost greatly reduced. Save battery to avoid the battery of secondary pollution, and can improve the system of the mean time to failure. (3) the photovoltaic battery ponents and building perfect bination, can power and can be used as building materials and decoration materials, make full use of material resources play a variety of functions, not only is helpful to reduce the construction cost, and also improve the content of science and technology building, increase selling point. (4) distributed construction, came near to the in situ dispersion reality, enter and exit grid agile, is advantageous to enhance power system against war and disasters, and to improve the ability of power system load balance, and can reduce the loss of line. (5) the load effect. Networking solar photovoltaic system is the world of the advanced countries in the development of photovoltaic application fields are hot and 湖北理工學(xué)院 畢業(yè)設(shè)計（論文 ） 外文文獻(xiàn)翻譯 11 key, is the world39。 Also have distributed small grid 湖北理工學(xué)院 畢業(yè)設(shè)計（論文 ） 外文文獻(xiàn)翻譯 9 generation system, especially PV power generation system, building integration is the mainstream of the bined to the grid. 1 current grid photovoltaic power generation system A current grid photovoltaic power generation system: when the solar photovoltaic system generated electricity plenty, but will be surplus power supply into the public power grid, the grid power supply (sell electric)。聯(lián)網(wǎng)太陽能光伏系統(tǒng)是世界各發(fā)達(dá)國家在光伏應(yīng)用領(lǐng)域競相發(fā) 展的熱點和重點，是世界太陽能光伏發(fā)電的主流發(fā)展趨勢，市場巨大，前景廣闊。省
