Smart-tie Microgrid

Smart-tie™  Microgrid Automated Microgrid Managment

Smart-tie Microgrid solutions take Smart-tie operation to the next level, enabling full microgrid (intentional islanding) operations. In a microgrid, GridWave-enabled Petra Solar SunWave solutions are capable of bringing up the grid from a complete off state (black start) and managing the microgrid load across all GridWave devices. Additionally, if the microgrid is capable of grid-tie through a smart switch, Smart-tie Microgrid devices are able to automatically synchronize with grid frequency and voltage for seamless connection, with similar autonomy for smooth disconnect from the grid.

The Smart-tie MicroGrid package includes:

• Microgrid black start
• Support for seamless transition to and from grid-tie
• Automated load sharing (among GridWave compatible devices)

PLUS All Smart-tie features

• Reactive power (volt-VAR) injection (automated)
• AC output power level curtailment (automated)
• AC output power curtailment (manual)
• Reactive power (VAR) injection (manual)
• Voltage operating window setpoints
• Frequency operating window setpoints
• Voltage ride-through controls
• Power ramp rate management
