The main structure of the integrated Photovoltaic energy storage system is to connect the photovoltaic power station and the energy storage system as a whole, make the whole system work together through a certain control strategy, achieve the effect that cannot be achieved by a single system, and output the generated electricity to the power grid.
The main advantage of the integrated Photovoltaic energy storage system is that it can combine the advantages of the two single parts to overcome its own shortcomings. For example, the output of the PV system is not balanced, and its volatility and intermittentness are greatly affected by the environment.
