Process-Knowledge-Embedded Safe DRL for Real-Time Dispatch of Process Loads in Industrial Microgrids
Daniyaer Paizulamu, Lin Cheng, Fashun Shi +2
Steelmaking process loads (SPLs) are flexible resources that enhance local renewable-energy utilization and reduce electricity procurement costs in industrial microgrids. However,…
Coordinated Primary Frequency Regulation and Grid-Forming Control for Wind Turbine Generators
Meng Chen, Yufei Xi, Lin Cheng +4
Conventional grid-forming (GFM) control strategies often treat the DC source as an unconstrained link, creating mismatches when applied to the wind turbine generators (WTGs). Focus…
Reference-Free Heterogeneous Multi-Agent Reinforcement Learning for Grid-Friendly Tie-Line Power Shaping in Industrial Microgrids
Daniyaer Paizulamua, Lin Cheng, Fashun Shi +3
Tie-line power (TLP) shaping is a key requirement for the grid-friendly operation of industrial microgrids (IMGs). This paper studies the coordination of multi-timescale heterogene…
LCL Resonance Analysis and Damping in Single-Loop Grid-Forming Wind Turbines
Meng Chen, Yufei Xi, Frede Blaabjerg +2
A common assumption in both grid-following (GFL) and grid-forming (GFM) control systems is that they are open-loop (OL) stable in the vicinity of high-frequency resonances. Hence c…
Comparison of Droop-Based Single-Loop Grid-Forming Wind Turbines: High-Frequency Open-Loop Unstable Behavior and Damping
Meng Chen, Yufei Xi, Lin Cheng +2
The integration of inverter-interfaced generators introduces new instability phenomena into modern power systems. This paper conducts a comparative analysis of two widely used droo…
