LCL photovoltaic grid-connected inverter current inner loop control method
This paper proposes a simple current control scheme, based on the combination of deadbeat and PI control, for a three-phase voltage source inverter connected to the grid via an LCL filter. The compensation unit can effectively compensate the system's phase around the crossover frequency, greatly enhancing the system's phase margin and stability. It is also capable of handling weak-grid. Abstract-The utilization of inverters for the interconnection of distributed generators to the grid requires application of control systems capable of regulating the active and reactive output current, ensuring high power quality levels and achieving relative immunity to grid perturbations.

Solar inverter decoupling control
In this article, I present a comprehensive analysis and design of an inverted decoupling maximum power point tracking (MPPT) control scheme for cascaded H-bridge multilevel inverters, which are crucial in solar inverter applications. The goal is to in-crease the X/R ratio to 10 or more to make the feeder impedance inductive. Unlike conventional phase-locked loop (PLL)-based methods, which suffer from coupling effects between synchronization and current control loops, our. Grid-forming, particularly those utilizing droop control and virtual synchronous generators (VSG), can actively regulate the frequency and voltage of microgrid systems, exhibiting dynamic characteristics akin to those of synchronous generators. Although droop control and VSG control each have. Although droop control and VSG control each have distinct benefits, neither can fully meet the diverse, dynamic needs of both grid-connected (GC) and islanded (IS) modes.
