Power Grid Stabilization (PGS) module

Features at a Glance

Reliable and Scalable

Factory prepackaged and tested

• Pre-engineered containershipped as a single unit with batteries, inverter, isolation transformer and other equipment installed.
• Parallel ready - multiple modules may be used in parallel to increase total output up to 100+MW.

Renewable Integration

• Designed to work with an array of renewable systems, including solar and wind
• Seamless integration with Cat Microgrid Master Controller (MMC) allows for maximum renewable penetration and full asset control

Transient Assist

When used with a generator set, the Cat PGS module will provide reserve power capacity to:

• Decrease the transient voltage and frequency dips resulting from the application of large loads.
• Enables highly-efficient lean-burn gas gensets to operate in island mode.

Grid Stabilization

• Protects against many typical power problems, including power failure, voltage sags/surges, and under/over frequency conditions.

High Performance Inverter

• Built-in controls for the charging and discharging of the energy storage equipment.
• Static VAR compensator.
• Four-quadrant output power factor control.
• Automatic anti-islanding to meet UL 1741 and synchronization back to grid.
