Global Survey of Technologies and Industrial Applications of Grid Forming Energy Storage Systems
Heng Wu, Changjiang Zhan, Jiacheng Li +2
Grid-forming (GFM) energy storage system (ESS) is a key enabler for stabilizing future power systems with high penetration of converter-based resources (CBRs). To get a better over…
Analysis and Enhancement of Incremental-Quantity-Based Distance Protection With Grid-Forming Inverters
Henrik Johansson, Qianli Xing, Nathaniel Taylor +1
Grid-forming (GFM) inverters are expected in future inverter-dominated grids. In such grids, time-domain protection schemes, for example those based on instantaneous incremental qu…
Impact of Grid-Forming Inverters on Protective Relays: A Perspective for Current Limiting Control Design
Yifei Li, Heng Wu, Xiongfei Wang
Grid-forming (GFM) inverters can significantly alter the fault characteristics of power systems, which challenges the proper function of protective relays. This paper gives a holis…
A Protection-Interoperable Fault Ride-Through Control for Grid-Forming Inverters
Yifei Li, Heng Wu, Xiongfei Wang
Differing from synchronous generators (SGs), grid-forming inverter-based resources (GFM-IBRs) exhibit rapid variations in their output impedances during transmission line faults du…
Analysis of Power Swing Characteristics of Grid-Forming VSC System Considering the Current Limitation Mode
Yongxin Xiong, Heng Wu, Yifei Li +1
This paper investigates power swing characteristics of grid-forming voltage source converter (GFM-VSC) systems considering the current limitation mode in both non-inertial and iner…
