摘要: 冬季供暖期内,因热电冲突带来的供热机组调峰能力受限是中国“三北”地区出现大量弃风现象的主要原因。为促进新能源规模化消纳,以锡林浩特600 MW太阳能-燃煤热电联产系统为研究对象,建立了太阳能集热场、热电联产机组等关键设备数学模型,在实际气象条件及负荷需求下,研究太阳能-燃煤热电联产系统与100 MW风电场的多能协同运行特性及年综合性能。结果表明,相比于原机组,太阳能-燃煤热电联产机组调峰下限可下降150 MW,从而促进风电规模化并网;在配置有51万m2槽式集热场、3 h蓄热罐的情况下,年弃风量从0.21 亿kW·h减少至0.07 亿kW·h,弃风率从7.91%下降至2.70%,下降幅度为62.2%;同时,太阳能集热发电量为1.5 亿kW·h,共可节煤4.9万t/年,减少二氧化碳排放13.2万t/年,效益显著。

Abstract: During the heating season, the limited peak shaving capacity of CCHP units is blamed as the major cause for the massive abandonment of wind and light in the "Three Norths" area. A mathematical model of key equipments for the solar aided CCHP system is established in this paper. Then a desk-top case of a 600MW direct air-cooled CCHP unit with a 100 MW wind farm, 510,000 m2 solar field, and 3-hours storage system is investigated under actual weather conditions and load demands. The simulation results show that, in the heating mode, the lower limit of unit peak shaving can be reduced by 150 MW for wind power consumption so as to promote the integration of large scale wind power into the grid. The annual wind curtailment has dropped from 20 million kW·h by 62.2% to 7 million kW·h, and the wind curtailment rate has dropped from 7.91% to 2.7%. Meanwhile, the annual solar power generation has reached 150 million kW·h, equivalent to a total of 49000 tons of coal saved and 132000 tons of carbon dioxide emissions reduced, which has demonstrated significant environment and economy benefits.
