光伏发电对蓄电池的基本要求及理想储能方法

太阳能光伏发电系统需要储能蓄电池。对于独立功放发电系统需要蓄电池是可以理解的;对于并网光伏发电系统,为了减少太阳能发电对电网稳定性的影响,对电网有功分量的补偿只有依靠蓄电池或者其他储能装置。什么是太阳能光伏蓄电池?在光伏界还没有一个统一的认识,于是各蓄电池生产厂家纷纷推出自己的所谓太阳能光伏蓄电池,这些蓄电池能够符合太阳能光伏储能的基本要求吗?究竟什么是太阳能光伏蓄电池?对于太阳能光伏发电系统,理想的储能元件应该具备什么技术要求?本文试图通过分析解答以上问题。

Solar photovoltaic storage battery basic requirement and ideal energy storage method

Solar PV systems require energy storage batteries.For an independent power amplifier electricity generation system,it is understandable that storage batteries are needed.But for a grid connected PV system,in order to reduce solar impact on the power network stability,the compensation to active component in power network only relies on storage battery or other energy storage devices.What’s solar PV storage battery ?There is no common understanding in solar PV field yet.Then storage battery manufacturers work out their own so-called solar PV storage batteries.Can these batteries meet the basic requirements for solar PV energy storage? What’s solar PV storage battery ?What’s technical requirement for an ideal energy storage component in solar PV system?This paper attempts to answer these questions by analysis.
