Improved Droop Control Strategy for Grid-Connected Inverters


In this project, the load and/or grid linked with an inverter is made as the combination of voltage sources and current sources at harmonic wavelengths. Moreover, a droop control technique is designed for systems providing power to a continuous current source, instead of a continuous voltage source. This is then used to create a harmonic droop operator so that the right amount of harmonic voltage is added to the inverter reference voltage to make up the harmonic voltage decreased on the outcome impedance due to the harmonic current. Simulation results are offered to show that the suggested technique can considerably improve the voltage THD.
