摘要
在对微电网多年研究成果的基础上,设计和建立了一套以4 kW光伏方阵为主体、500W48V质子交换膜(PEM)燃料电池为辅助电源、25 kWh磷酸铁锂离子梯次动力电池组为固定储能组、小型电动车14 kWh动力电池组为机动储能组的离网型光伏全直流微电网实验系统,并配置了相关的数据检测和远程控制模块。该离网型光伏全直流微电网实验系统的实机运行测试结果表明,光伏方阵至MPPT输出端的发电效率为92%左右,微电网实际能效比为84%左右。离网型光伏全直流微电网可为无电或灾害地区、军用及紧急供电等多种场景提供电源解决方案。
Based on the basic research results of microgrid over the years,the author designed and established an off-grid type PV full DC microgrid experimental system with 4 kW PV array as the main body,500W48V proton exchange membrane(PEM) fuel cell as the auxiliary power supply,25 kWh lithium iron phosphate ion echelon power battery pack as the fixed energy storage group and 14 kWh power battery pack of small electric vehicle as the mobile energy storage group.It is equipped with relevant data detection and remote control modules.The actual operation test results of the off-grid type PV full DC microgrid experimental system show that the power generation efficiency from PV array to MPPT output is about 92%,and the actual energy efficiency ratio of the microgrid is about 84%.Off-grid type PV full DC microgrid can provide power solutions for many scenarios such as no power or disaster areas,military and emergency power supply.
