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 mathematical model of a grid-connected photovoltaic inverter based on the VSG is built. The proposed control strategy provides the inverter with more disturbance attenuation and provides rotational inertia. The control strategy estimates and compensates the total disturbance and generates the reference active power and reactive power by ADRC.
Often, it leads to fire, then the equipment is completely burnt. For an example, in the Egyptian PV power plants, the Functions of the PV grid connected inverter are defined based on the grid code requirements (Voltage, Frequency, Reactive Power, THD, , etc.).
Power systems in other parts of the world have identified a potential risk to system operation due to large numbers of photovoltaic (PV) system inverters simultaneously disconnecting from the grid in response to a frequency disturbance.
AEMO undertook a study to investigate how small inverters that connect photovoltaic generation to the electricity network are likely to respond to frequency disturbances. This report is based on information available to AEMO as at May 2015 although AEMO has endeavored to incorporate more recent information where practicable.
Grid-tied PV inverters also have the characteristics of tripping under grid events due to its settings. Disconnection or a dramatic reduction of real power delivered to the grid can occur during grid overvoltages and undervoltages, also during over/under frequencies .
