As alternative energy sources become more common, the need for an interface between the energy sources and the existing power generation grid increases. Three-phase inverters are commonly used to convert the dc electric energy generated by alternative energy sources to ac electric energy that is compatible with the utility system .
The main purpose of this paper is to conduct design and implementation on three-phase smart inverters of the grid-connected photovoltaic system, which contains maximum power point tracking (MPPT) and smart inverter with real power and reactive power regulation for the photovoltaic module arrays (PVMA).
From tracking the phase, the control of a three-phase inverter can be practically implemented using current control. Given a PLL system and current control algorithm, a Simulink model will be used to simulate the control of a three-phase inverter.
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.
