摘要：
Based on the active advantages of photovoltaic multi-function grid-connected inverter (PVMFGCI) in power quality control and harmonic resonance suppression, and combined with the output characteristics of photovoltaic power generation system under different output states of the inverter, the optimization method of reactive power and harmonic for PVMFGCI under different output states is proposed. In the proposed three-layer optimization strategy, the upper-layer optimization strategy takes the maximum grid-connected active power as the objective function, the middle-layer optimization strategy takes the total harmonic distortion rate and voltage deviation to reach the specified targets of corresponding power quality as the objective function, and the lower-layer optimization strategy takes the minimum harmonic distortion rate and voltage deviation as the objective function, which is solved by the adaptive ant colony algorithm. Taking the IEEE 33-bus system as the example, the results show that the optimization method based on different output states of the inverter can effectively improve the power quality of power grid and improve the economy of power grid operation. On the basis of stable operation of the system, the PVMFGCI can stage control harmonics and adjust voltage deviation by primary and secondary under different output states, and its control effect is better. © 2024 Electric Power Automation Equipment Press.
