In general, the power distribution of a parallel inverter is achieved by the use of droop control in a microgrid system, which consists of PV inverters and non-regeneration energy source inverters without energy storage devices in an islanded mode. If the shared load power is no more than the available maximum PV inverter output power, then there is a …
