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. The grid-connected, three-phase PV inverters’ electrical circuitry.
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).
Three-phase string inverter systems convert the DC power generated by the photovoltaic (PV) panel arrays into the AC power fed into a 380 V or higher three-phase grid connection.
The analyzed topologies of the three-phase inverters were configured to supply a three-phase inductive load (10-Ω resistance in series with 5-mH inductance) from a low-voltage dc supply; an input dc voltage or Photovoltaic Panel of 100 V was assumed for the simulation, whereas 20 V was used in the experimental design.
Reactive power is required to increase the electrical grid’s capacity. Consequently, a PV inverter providing reactive power is necessary. A PV power system that is currently in use needs a dependable power source to function . The most powerful system is the PV power conditioning unit.
The extended power and commercial three phase inverters are provided with an integrated DC Safety Switch and with terminal blocks for the connection of three strings per unit, eliminating the cost of an external DC combiner box.
