摘要

在本文中,我们使用MHOGA软件来评估在公用事业规模的光伏发电系统中增加抽水蓄能(PHS)以进行能源套利。利用小灵通进行电价套利,在电价较低的时段利用光伏发电从下水库抽水到上水库,在电价较高的时段利用水轮机蓄水发电(在此时段,光伏发电机组也将其生产的电能注入电网)。该控制策略为泵和涡轮机的使用设置设定值,试图从出售给电网的电力中获得最大收益,最大化净现值(NPV)。最后给出了一个应用实例,得出了PV-PHS系统与纯PV系统相比的经济可行性的结论:在本工作研究的案例中,PV系统不值得添加PHS。

Energy arbitrage in PV-PHS systems
In this paper, we use MHOGA software for the evaluation of adding pumped hydro storage (PHS) for energy arbitrage in utility-scale PV generating systems. PHS is used for electricity price arbitrage, pumping water from the lower reservoir to the upper reservoir with the PV generation during hours of low electricity price and generating electricity by means of the stored water with the turbine during hours of high price (during these hours the PV generator also injects its production to the grid). The control strategy creates setpoints for the use of the pump and the turbine, trying to obtain the maximum benefits from the electricity sold to the grid, maximizing the net present value (NPV). An example of application is shown, obtaining conclusions about the economical viability of the PV-PHS system compared to the PV-only system: in the case studied in this work, it is not worth to add PHS to the PV system.
