Presented in this paper is a method of bidirectional real and reactive power control of a three-phase grid-connected inverter under unbalanced grid situations. Unbalanced three-phase load and unbalanced grid impedance are illustrations of unbalanced grid issues that have been investigated.
Figure 1 depicts the circuit architecture for the three-phase grid-connected PV inverters. The PV array, boost converter, DC connection, and inverter make up the inverter. The MPPT controls the boost converter. The transfer of control of the grid’s active and reactive functions is powered by a three-phase inverter. Fig.1.
This example shows how to control the voltage in a grid-tied inverter system. The Voltage regulator subsystem implements the PI-based control strategy. The three-phase inverter is connected to the grid via a Circuit Breaker. The Circuit Breaker is open at the beginning of the simulation to allow synchronization.
Integrating these into the conventional AC grid requires power electronics converters, particularly inverters that produce high-quality AC waveforms synchronized with the grid. This project simulates a three-phase inverter topology widely used in grid-tied renewable applications, focusing on efficiency and power quality.
