This paper proposes a secure system configuration integrated with the battery energy storage system (BESS) in the dc side to minimize output power fluctuation, gain high operation efficiency, and facilitate fault ride through, which is suitable for unidirectional renewable power generation systems (power transfer from renewable sources to the .

DC Coupling: With this choice, the BESS and the PV are interconnected on the DC side of the batteries and of the PV modules, by means of a specific DC/DC converter to stabilize the voltage. This solution allows sharing the inverters between the PV module and BESS (in this case the inverter shall be able to operate in all the 4 quadrants of P-Q .

The main advantage of the DC-Coupled energy storage solution is the ability to PV clip recapture with a higher DC/AC ratio. Another major benefit is the smaller size of the inverter per PV Watt. With a DC-Coupled photovoltaic PV storage system, the DC/AC ratio goes as high as 2.5, allowing for a lot of PV power being fed through a relatively small.

The DC/DC converter suitable for the energy storage system requires control of the energy flow in both directions, so a Boost/Buck bidirectional converter is used. In order to provide sufficient voltage, the power-based energy storage side still needs some devices connected in series.
