Can a three-port converter work in a stand-alone PV storage power generation system?

To address the instability of the input voltage of photovoltaic (PV) in a stand-alone PV storage power generation system, a wide input range non-isolated three-port converter that can operate in a range that is greater than and less than the voltage of the storage port is proposed in this paper.

Why is a PV port a good energy management strategy?

In addition, it can be flexible in selecting the voltage level of the energy storage port to meet the practical needs of the wide input range variation of the PV port voltage. The design of an energy management strategy can ensure fast switching between modes.

How does a battery port affect the energy transfer?

However, the energy flow from the PV port to the load port must pass through the battery port, which reduces the efficiency of the energy transfer from the PV port to the load port. In addition, there are no common grounds between the three ports of the PV, the battery, and the load.

Why is energy storage a critical port function?

Ensuring availability of these electrical resources to meet loads which are intermittent and uncertain is becoming a critical port function. It requires investment in multi-vector energy supply chains, energy storage in ports and their associated energy management systems.
