Power control for grid connected applications based on the phase shifting of the inverter output voltage with respect to the grid voltage

A remote islanding detection and control strategy for photovoltaic-based distributed generation systems

“…These conditions change from the grid reference values such that the circuit breaker (CB) connected between the grid and the point of common coupling (PCC) clears the fault during islanding mode. Meanwhile, DG still supplies power to the local load if the CB cannot open the circuit [5]. Voltage shutdown, equipment failure, and short-circuit conditions cause an unpredictable interruption of the grid, and these abnormal conditions cause islanding operation in a PV system [6].…”

Performance Evaluation of Two-Level Photovoltaic Voltage Source Inverter Considering SPWM and SVM Switching Controller

“…In current control mode, the aim is to regulate the current that the inverter supplies into the network [5]. In voltage control mode, it is significant that the inverter generates a proper voltage waveform wherethe voltage must be kept with fixed amplitudeand fixed frequency, irrespective of the load types [18].…”

“…The harmonics seems to be the main power quality issue [5]. Harmonics lead to equipment overheating, increasing of losses, and waveforms distortion [6].…”
