In this work, an inverter has been proposed that optimizes the electrical microgrid performance and operation. With the inverter, the microgrid can manage the interchange of power with the power system whenever, making the interchanged power the only active power. The inverter can work in grid-connected or in isolated mode when appropriate.
When the load is connected, the power system voltage is out of range, and the inverter voltage control fixes the voltage to the load and supplies all the power required. At a time of 30 s, the grid voltage is restored and the current control is imposed. In this case, the microgrid voltage is set by the power system.
The modern power system integrated with inverter-based resources (IBRs), such as solar and wind utilizes complex control strategies to preserve grid stability. This paper introduces an improved control structure of a grid-forming inverter (GFMI) for a standalone (SA) microgrid system.
Conclusion A simple voltage control method for parallel inverters in microgrid has been proposed. The problem of voltage and frequency disturbance in the islanding operation of microgrid is addressed. The proposed control technique prevents the voltage and frequency fluctuation during the switch on and off of large loads.
