This paper provides a proportional-integral (PI) controller and direct-quadrature (DQ) frame transformation-based optimum control method for a three-phase grid-connected inverter. In terms of grid synchronization, voltage regulation, and harmonic abatement, the proposed control technique attempts to improve the inverter''s performance.
PI controller Grid inverters and other control systems frequently use the proportional-integral (PI) controller as a control mechanism. API controller is frequently used in the context of a grid inverter to control the electricity flow between renewable energy sources (like solar or wind power plants) and the grid.
The power generated travels via a three-phase inverter on its way from generation to consumption, operating in accordance with the DQ principle to ensure smooth communication with the grid.
In terms of grid synchronization, voltage regulation, and harmonic abatement, the proposed control technique attempts to improve the inverter''s performance. By separating the control of active and reactive power, the control structure is made simpler and independent regulation of these parameters is possible.
