In addition to fundamental differences in fault current capability compared to traditional synchronous generators, PV inverters characteristic response to abnormal conditions is a strong function of the inverter controls implemented to protect the PV inverter itself but also to safely integrate to the interconnected grid.
However, challenges related to power quality, stability, and power output mismatches arise when PV systems are connected to the grid via inverters. Inverters, being pivotal power electronic converters, convert the DC from RES to AC, enabling the supply of electricity to AC loads or the utility grid 5.
This work investigates the specific response of a utility-scale PV inverter to grid voltage phase shift-type disturbances which sometimes occur during grid fault events. The role of the PV inverter’s phase-locked-loop (PLL) is identified as important to modeling the response.
The inverter helps the PV system supply electricity to the grid by coordinating its AC output with the frequency and voltage of the grid. One of the key elements during this conversion procedure is the introduction of an AC filter, that rejects high-frequency harmonics while allowing only clear, high-grade power to feed into the supply to the grid.
