Adaptive Control Strategy of Grid-Connected Inverter 3.1. Adaptive Control Strategy of Power Grid Voltage PV inverters need to control the grid-connected current to keep synchronization with the grid voltage during the grid-connection process.
For the inverter grid voltage adaptability, the more stringent level I response in IEEE 1547-2003 requires that the inverter should maintain continuous operation at 0.7~1.1 pu, and, after exceeding this range, it should be taken off the grid within the specified time according to the standard.
Firstly, it has carried out a comprehensive review of the adaptability connotations of photovoltaic grid-connected inverters both at home and abroad, distinctly defining the adaptation benchmarks and requisites in aspects such as grid voltage, frequency, and harmonics.
