View moreConclusion This paper has reviewed the current control strategies for single phase grid integrated photovoltaic inverters. From the above study, it can be concluded that the MPCC scheme shows best steady state performance as compared to other schemes. It also achieves effective harmonic mitigation in terms of reduced THD value of output current.
The control design of this type of inverter may be challenging as several algorithms are required to run the inverter. This reference design uses the C2000 microcontroller (MCU) family of devices to implement control of a grid connected inverter with output current control.
The grid integrated inverter has stringent control requirements. A current controller is employed to mitigate the harmonics in the current injected into the grid and regulate the power exchange between the plant and the grid.
Thus, this work presents the modeling and control of a single-phase grid-connected multifunctional converter, which operates as a current-controlled voltage source inverter using an LCL-type output filter.
