Grid Forming Converters

A hardware platform that facilitates the design , development and validation of grid forming ( GFM ) control for power electronics converters . This maximises grid supporting functionalities from inverter-based resources ( IBRs ) and battery energy storage systems ( BESS ) in power electronics defined power systems .

Competitive Advantage

• Expertise in modelling and control of grid-connected power converters
• Expertise in power electronics , combined AC / DC networks , and power-systems integration
• Capability of developing multi-converter power systems
• Capability of replicating extreme grid events
• Capability of implementing power hardware-in-theloop testing

Impact

• ‘ Responsible grid-forming design that coordinates grid supporting services with power and current limits for power converters
• Demonstration of grid support capabilities under extreme grid disturbances

Capabilities and Facilities

• Regatron DC / AC power supplies
• TDK-Lambda programmable DC power supply
• Danfoss power electronics converters
• Modular multilevel converter systems ( 48 SMs * 2 )
• Interface with real-time simulators for power hardware-in-the-loop testing
