Compound Feedback for Current-Controlled Grid-Side Inverters

Abstract: Мost grid-forming and grid-following inverters contain an LCL output filter and an internal current controller. The resonant nature of the filter interferes with the injection of high-quality grid currents, degrades disturbance rejection, and compromises stability.

Control interaction analysis of hybrid system with grid-following

In high renewable penetrated power systems, both grid-forming (GFL) and grid-following (GFM) inverters play an important role in maintaining the system stability and economic operation. However, the two kinds of inverters exhibit distinct dynamic characteristics; thus, interconnecting them in a close electrical distance may cause the stability

Mixed Grid-Forming and Grid-Following Inverters with Secondary

To address this issue, a mixed GFM and grid-following inverter scheme is proposed, where the GFM inverter is prioritized to provide active power to support the grid frequency while the GFL

Performance evaluation of grid-following and grid-forming inverters

There are two types of inverters that provide such fast response capabilities: grid-following (GFL) inverters and grid-forming (GFM) inverters [10]. GFL inverters are inverters with current source characteristics that are widely used today. They attempt to maintain active/reactive power constant in a transient time frame.
