摘要
With the application of renewable energy, the distributed energy network is researched and developed widely. This paper designed the distributed stand-alone PV generating system with battery backup. The coordinated MPPT control of several parallel modules is designed to increase PV utilizing efficiency. The multi-variable multi-loop controller is designed to control the currents of each module, the DC bus voltage and the AC voltage of inverter output. According to the different battery characteristics, the battery management is optimized for better performance and longer life time. The capacity and cost of the system can be optimized and decreased since the distributed energy generating and battery can provide the unintended power. The performance and total efficiency of PV generating system can be improved for stand-alone application. The experimental results of the prototype verify the effectiveness of proposed protocol and strategy.
