The inverter’s DC input current should always stay within its maximum limit. If the PV module’s output current exceeds this limit, it may lead to current-limited operation and potential inverter damage, reducing power generation efficiency and return on investment.
The results under two-phase and three-phase dip in the grid voltage shows that the proposed control strategy injects maximum reactive and active power and limits the inverter current by quickly activating the APC control loop during fault-ride-through period.
The control of grid-connected inverters is recently executed with digital microprocessors due to the advances in digital signal processing technology. However, the digital realisation has a drawback of the phase lag induced by the time-delay. This phase lag challenges the stability and robustness of the controller of the inverters.
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 boost converter and switching frequency of the three-phase inverter are defined for the 380V/50Hz three-phase PV power conditioning system. 2.1 MPPT Algorithm
