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...
The energy storage devices are necessary to the stand alone PV generation system. Lead acid battery which performance is specially designed is suitable for PV generation application. The battery charging and discharging control with the max power of PV array is the key point to increase efficiency of the generation system. In this paper, the new system configuration with parallel battery charger is...
