摘要
考虑到风电并网因风功率波动性所引起的电能质量与电网稳定性问题,提出了一种新型的风能利用形式风热装置,并将风热装置引入槽式光热电站,构建了一种新的可再生能源发电形式——风光热电站,给出了风热装置与槽式光热电站的连接方式,基于美国国家新能源研究所在科罗拉多州戈尔登地区实测的2011年全年风速、光照强度数据,利用牛顿插值法计算风电输出功率,同时采用槽式光热电站输出功率模型计算其输出功率,从风热装置与槽式光热电站发电量的角度,分析了风能光能在时域上的互补性,进而对风光热电站进行了成本估计,为验证风光热电站的可行性与优势提供了依据。
As the wind power fluctuation of the integrated wind farm influences the power quality and the stability of the grid. This paper proposes a new way of utilizing wind energy-wind-heat device and estimates its cost. Considering the instability of the trough system＇s generation and its high investment cost, a new sustainable energy generation technolo- gy-solar/wind hybrid thermal power plant is presented and its combination is given. Based on the actual irradiance and wind speed dates of Golden, Colorado, USA which are provided by American National Renewable Energy Laboratory, the Newton interpolation method is applied to calculate the wind power. Meanwhile trough system＇s output model is used to calculate its output. According to the generation of the wind thermal device and the trough system, the wind/solar com- plementarity is studied, which gives a strong prove to the feasibility of the solar/wind hybrid thermal power plant. Final- lv, a cost estimation of the solar/wind hybrid thermal power plant is studied.
