Energy storage systems (ESSs) can be coupled to the CIG either on the DC or the AC side of the power converter. When placed on the DC side, the ESS can provide damping of the variability in the generation but would require significant modification to the wind turbine hardware.
This document examines DC-Coupled and AC-Coupled PV and energy storage solutions and provides best practices for their deployment. In a PV system with AC-Coupled storage, the PV array and the battery storage system each have their own inverter, with the two tied together on the AC side.
In a PV system with AC-Coupled storage, the PV array and the battery storage system each have their own inverter, with the two systems tied together on the AC side. The two systems are thus electrically separated, allowing a customer to size each separately.
An AC-coupled solar and storage site is compared to two separate stand-alone sites. Figure 1 - Diagram illustrating the setup of the main components of solar and storage projects, both stand-alone (left) and co-located through AC coupling (right). In the first example, two stand-alone projects exist, one battery energy storage and one solar.
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.
AC-Coupled PV and energy solutions are employed as PV retrofits or where the storage component differs from the PV component widely in power rating. The main advantage of the DC-Coupled energy storage solution is the ability to PV clip recapture with a higher DC/AC ratio.
