Photovoltaic cluster inverter resonance suppression
Abstract: A resonance problem in the cluster system of string-type photovoltaic cluster using LLCL type inverters, this paper analyzes the resonance mechanism of the cluster system and proposes a method to suppress global resonances. Analyzes and discusses two aspects of passive damping global. . In response to the key engineering problems of photovoltaic grid-connected inverter cluster resonance suppression affected by grid-connected inverter impedance, in this paper, a control strategy based on a disturbance observer is proposed to dynamically compensate for the damping coefficient of the. . Abstract:Photovoltaic cluster power generation can improve the power generation efficiency of photovoltaic power plants, but the photovoltaic cluster inverter will produce resonance after the grid, affecting the safe and stable operation of power systems. This approach effectively. . when multiple inverters are connected to the grid. Analyzes and discusses two aspects of passive damping global resonance. .
