Demonstrated in this article is the use of a three-phase inverter to inject power into or absorb power from the grid in the situation of an unbalanced load and unbalanced grid impedances.
Under unbalanced grid situations, a modified PR control strategy (MPRS) for controlling the power of grid-connected three-phase inverters was presented in . The premise behind this method is that the system is operating with an unbalanced load and an unbalanced grid current.
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.
A variety of control techniques have been used to control the power and current of grid-connected three-phase inverters, including proportional-integral (PI) and proportional-resonant (PR) control methods [4, 5]. These approaches, on the other hand, simply examine balanced grid situations.
