摘要
针对常规离网型光伏发电系统和氢气蓄能式光伏发电系统所存在的不足,提出了组合蓄能光伏发电系统及其优化设计方法。该方法不仅可以消除太阳辐射和用户负荷间供需失配的影响,而且能够实现系统运行和成本的优化。此外,还提出系统成本的计算方法。以我国北京地区的家庭用户为例,对各种光伏发电系统进行了仿真验证,并对其发电成本进行了分析比较。
An optimization methodology for the PV system with hybrid energy storage was proposed, addressing the shortcomings of the off-grid conventional PV system and the PV system with hydrogen energy storage. The methodology can not only eliminate the effect of solar irradiation and mismatching between users, but also achieve the optimization of system operation and cost reducing. Moreover, the system cost calculation method is developed. Case studies are carried out to testify the effectiveness of the proposed PV generation system and its design method. An electricity cost analysis was also provided.
