With the continuous expansion of floating photovoltaic (FPV) power plant cluster scale, grid-connected oscillation problems have posed significant threats to the stability and security of power systems. This study deeply analyzes the root causes of grid-connected oscillations, including interactive effects among clusters and dynamic characteristics of power electronic devices. A suppression strategy based on multi-band coordination control is proposed, involving the construction of an adaptive control model to optimize system damping characteristics. Simulation results verify that the strategy effectively reduces oscillation amplitude and enhances system dynamic stability. The research findings provide technical support for the stable grid-connected operation of FPV power plant clusters and hold important significance for promoting the large-scale application of clean energy.
