Jan 3, 2022 · Abstract—This paper presents a novel control structure and control synthesis method for regulating the output volt- age/frequency and power injection of DC-AC inverters.
This indicates that when the output impedance is considered purely inductive, the power angle has a more significant impact on the active output power injected by the inverter into the common bus, while the voltage magnitude primarily influences the reactive power .
Power converters are key grid parts for connecting distributed generation facilities to the energy network, and enhancing the control function of power electronic converters in microgrids is important [19, 20].
In , the authors propose an enhanced method for regulating the voltage and frequency of an island microgrid using droop control. A modified PID controller governs the internal voltage and current loops, while droop regulation is utilized to improve frequency and voltage regulation and reduce response time.
Droop control does not contribute to the inertia and damping coefficient required for the energy system. A virtual synchronous generator can provide the capabilities of a synchronous generator by using droop control loops to improve the rotor inertia response and regulate the terminal voltage [170, 171].
Inertia droop control by combining the advantages of conventional droop regulator and synchronous generator regulation is proposed in , this method has virtual inertia, and also by adding a compensator to the output energy part of the energy control loop. Active improves the dynamic response of the system.
Droop characteristics are the basis of active energy and reactive energy regulation in virtual synchronous generator and droop regulation methods, and the only difference between them is that the virtual synchronous generator method has virtual inertia, but the droop control method has no inertia [168, 169].
