How to make sure power is always flowing where it should When operating a PV plant, the goal is to of course get as much solar energy onto the grid or the connected load. In a PV only installation, this is generally a straight forward process. The sun hits the solar panels which in turn push energy through conduit through an inverter.
The sun hits the solar panels which in turn push energy through conduit through an inverter. In a DC-coupled Solar + Storage system, where a battery is installed in front of the inverter along with the PV, power can flow either directly to the grid through the inverter or to the battery where it can be stored and later discharged to the grid.
As shown in Fig. 8, PV supplies 1.74 kW with the irradiation of 250 W/m 2, and the battery buffers it with 4.3 kW to feed load with constant output voltage and to charge the supercapacitor pack that can compensate the system at the transient conditions.
During the reverse power flow operation, storage units are charged with constant currents of 4.4 A for supercapacitor and 15 A for the battery. The CC to CV control loop transition also has been performed for reverse power flow operation. Fig. 9, Fig. 10 show the performance results of the related condition.
It has three input ports for interfacing PV, battery and supercapacitor, among which in two of them bidirectional power flow is performed. The load connecting to the fourth port, which is the output port of the proposed converter, is fed by a PV system and buffered by a hybrid energy storage system (HESS).
Pushing an electrical charge into a PV panel can damage the panel. Unfortunately, in certain Solar + Storage or PV repowering situations, this damaging result can occur.
