Research on Adaptive Suppression Method for Cluster Resonance of String Type Photovoltaic Inverters
The conventional cluster resonance adaptive suppression method for string photovoltaic inverters uses the maximum power point tracking method to eliminate low order harmonics,which is easily affected by the dual feedback collaborative control effect and leads to high harmonic distortion rate.Therefore,it is necessary to design a new cluster adaptive suppression method for string photovoltaic inverters.A parameter estimation model for adaptive suppression of photovoltaic inverter clusters was constructed,and a resonant adaptive suppression strategy for string type photovoltaic inverter clusters was proposed to achieve resonant adaptive suppression of photovoltaic inverter clusters.The results show that the designed photovoltaic inverter cluster resonance adaptive suppression method has a good suppression effect,and the harmonic distortion rate is low under different output power percentages.It is reliable and has certain application value.
