摘要
根据全钒液流电池的物理特性,以负荷缺电率为指标,结合地区辐照度、环境温度等因素,研究了全钒液流电池应用到独立光伏系统中的容量配置问题,同时从经济性角度对系统运行成本进行了优化和分析。结果表明,全钒液流电池在规模储能方面具有较好的优越性,相对于传统铅酸蓄电池,采用全钒液流电池作为储能单元提高了系统供电可靠性,降低了发电单位运行成本。
A new energy storage technology of vanadium redox battery is applied in photovoltaic(PV) power system, which is compared to traditional lead-acid battery from their physical characteristics and economical efficiency. Based on the characteristics of vanadium redox battery and hourly average radiation, ambient temperature of some area, the sizing and techno-economical analysis of a stand-alone photovoltaic power system is presented in this paper. The method adopted is based on the loss of power supply probability (LPSP) concepts. And this paper also optimize the system levelized cost of energy (LCE) in the aspect of economy.Simulation results show that the techno-economical of vanadium redox battery is prior to lead-acid battery. And the system which adopts vanadium redox battery as energy storage can improve system probability and decrease operation cost.
