【摘要】：由于新能源发电装机容量不断增加、电网建设不同步等原因,出现了弃风、弃光等现象,造成了能源的浪费。通过综合能源系统形成多元消纳技术和多元存储技术可以增加可再生能源的就地消纳,提高风机利用率。该文首先介绍了电转气(power to gas,P2G)技术的原理,然后基于微网型能源集线器模型,将含P2G多源储能型微网系统划分为供给侧、转换组件和负荷侧三个部分进行模型。在此基础上建立基于经济最优的微网系统日前优化调度模型,考察P2G消纳可再生能源的潜力。最后在算例中采用三种不同场景的微网系统进行验证,结果证明P2G对弃风现象有很大的改善作用,具有良好的应用前景。
[Abstract]:Due to the increasing installed capacity of new energy generation and the unsynchronized construction of power grid, the phenomenon of abandoned wind and light appears, which results in the waste of energy. By means of integrated energy system, multivariate absorption technology and multiple storage technology can increase the local absorption of renewable energy and improve fan utilization ratio. This paper first introduces the principle of electropneumatic (power to gas,P2G) technology, and then, based on the micro-grid energy hub model, divides the multi-source energy storage microgrid system with P2G into three parts: supply side, conversion module and load side. On the basis of this, a pre-day optimal scheduling model for micro-grid systems based on economic optimization is established to investigate the potential of P2G to absorb renewable energy. Finally, three different scenarios of micro-grid system are used to verify the results. The results show that P2G can improve the phenomenon of abandoned wind greatly and has a good application prospect.
