Four quadrant paralleling control for inverters

Abstract

Presented herein are systems, devices, and methods for parallel control. A device may monitor for a transition in a first power signal corresponding to electrical power conveyed between an inverter and an electric bus. The device may identify, responsive to detecting the transition in the first power signal, a frequency in accordance with the transition in the first power signal and a frequency droop slope and a voltage in accordance with the transition and an amplitude droop slope. The device may modify the first power signal using the frequency and the voltage to generate a second power signal to maintain the power. The device may convey the electrical power between the inverter and the electric bus.
