To meet these requirements, a PQ control structure for the three-phase four-leg grid-connected inverter in a synchronous reference frame based on feedback linearization control ( FLC) is proposed.
Of course, the P-Q controllers of three-phase grid-connected inverters can be optimized by other theoretical PID methods . However, the P-Q control performance of three-phase grid-connected inverters can be further improved by adopting multi-objective evolutionary algorithms.
In photovoltaic grid-connected (GC) and DG systems, one of the objectives that the grid-connected inverters (GCI) is the control of current coming from the photovoltaic modules or DG units. In this way, this paper describes a simple P/Q control strategy for three-phase GCI. Initially, the proposed control of the grid side is introduced.
In Reference , an individual-phase decoupled P-Q control method based on six control degrees was proposed for a three-phase voltage source converter. Adhikari and Li proposed a P-Q control method with solar photovoltaic, maximum power point tracking (MPPT), and battery storage in the grid-connected mode.
