一种低成本高效率组串式光储系统

A Series Optical Storage System with Low Cost and High Efficiency

光伏发电有随机性、间歇性、波动性等不稳定性问题。当前主流的光储电站融合技术是采取集中式交流侧耦合的方式,集中式光储交流侧耦合系统成本高,能效转换率低,且占地面积大。为解决上述问题,提出一种低成本高效率的组串式光伏储能系统设计。在光伏系统的直流侧并入储能系统,将储能系统与光伏系统在直流侧进行紧密融合,相辅相成,实现光储智能融合。

Photovoltaic power generation has instability problems such as randomness,intermittence and fluctuation.At present,the mainstream optical storage power station integration technology adopts the mode of centralized AC side coupling.The centralized optical storage AC side coupling system has the advantages of high cost,low energy efficiency conversion rate and large floor area.In order to solve the above problems,a low-cost and high-efficiency series photovoltaic energy storage system is proposed in this paper.It is incorporated into the energy storage system at the DC side of the photovoltaic system.The energy storage system and photovoltaic system are closely integrated on the DC side to complement each other to realize the intelligent integration of optical storage.
