摘要
为了提高光电建筑的发电、供电、用电性能,配备电化学储能是必然的发展趋势。与大规模储能电站相比,光电建筑对于储能技术提出更高要求,然而目前电化学储能技术有一些不足之处,尤其缺乏适合建筑和建筑光伏系统的分布式电化学储能技术。建筑光伏系统应用储能的综合效益和大规模储能也有很大区别。研究光电建筑在消防安全方面对电化学储能提出的要求更高。在技术性能方面,研究建筑光伏系统要求储能蓄电池不仅适应部分荷电模式还适宜采用混合储能模式,以及要求采用能量密度较高的储能技术等问题。通过一个实际的建筑光伏直流供电系统的运行数据,分析了建筑光伏系统融合应用储能技术的一些综合效益,明确分析建筑光伏采用分布式储能的技术定位和经济定位,为建筑光伏系统和分布式储能技术的研究、应用、推广提供建议。
In order to improve the power generation, supply and use of photovoltaic buildings, it is an inevitable development trend to be equipped with electrochemical energy storage. Compared with large-scale energy storage power stations, photovoltaic buildings have higher requirements for energy storage technology. However, the current electrochemical energy storage technology has some shortcomings, especially the lack of distributed electrochemical energy storage technology suitable for buildings and building photovoltaic systems. There is also a big difference between the comprehensive benefits of energy storage in building photovoltaic systems and large-scale energy storage. The higher requirements for electrochemical energy storage in the fire safety of photovoltaic buildings are studied. In terms of technical performance, it has studied the requirements of building photovoltaic systems that energy storage batteries can adapt to some charging modes, it is more appropriate to adopt hybrid energy storage modes, and that energy storage technology with higher energy density is required. Through the operating data of an actual building photovoltaic DC power supply system, it analyzes some of the comprehensive benefits of building photovoltaic system integration and application of energy storage technology, and clarifies the technical and economic positioning of building photovoltaic systems using distributed energy storage, providing suggestions on the research, application and promotion of energy storage technology.
