Abstract
A method that can include coupling one or more loads of the system to a common direct current (DC) bus, measuring a voltage of the common DC bus, estimating a nominal voltage (Vnom) for the common DC bus, and determining a set point (DCSP) for each inverter based on the Vnom, where the inverters control a flow of DC current through the inverters based on the DCSP. A method that can include coupling one or more loads of the system to a common DC bus, measuring a voltage of the common DC bus, detecting a change in the voltage, managing a DCSP for each of inverters, where the inverters are configured to control the DC current flowing through the one or more inverters based on the DCSP, and managing DC current flowing through the inverters coupled between the ESS and the common DC bus.
