风—光—水互补发电系统的仿真与优化研究

发布时间：2020-12-11 22:55

　　在全球范围内,绝大多数人口主要依赖对环境有破坏作用的化石能源,如煤、石油、天然气(等。为了开发清洁的替代能源,很多国家开始研究以风能为代表的可再生能源,并将其与现有发电系统相结合。对风-光-水互补发电系统进行了仿真研究,以寻找解决巴基斯坦工业负荷较大这一难题的发电方案。该系统已在美国国家可再生能源实验室（NREL）开发的HOMER（多种可再生能源互补和分布式发电系统）软件包中实现。对5个系统案例进行分析,分别为:（1）风-光-水发电系统、（2）风-水发电系统、（3）光-水发电系统、（4）水发电系统、（5）电网系统。研究表明,与现有的电网系统相比,风-光-水互补发电系统降低了 42.85%的电费,并将电网能耗降低到33.98%,因此该系统成本最低。此系统可再生能源占比可达6 6%。该系统可通过增加可再生能源份额以降低电网中传统能源的比重,减少国家对化石能源的依赖,从而减少化石经济效应。该系统发电不仅可以通过出口增加国内生产总值,还有助于解决巴基斯坦能源短缺问题,促进巴基斯坦工业发展和经济增长。
