| Application | The Cat ECS 300 is used in a variety of microgrids where the Cat ECS 300 is configurable to meet applicable site-specific asset requirements. |
|---|---|
| Module Type | Monitoring / control and asset optimization may be configured with up to 4 Distributed Energy Resources (DER's). |
| Enclosure Rating | NEMA 1 wall mountable |
|---|
Control Modes | Auto | Grid Connected - Sub-modes (16):
- Utility parallel, import power from grid - Minimum import kW setpoint is maintained
- Unplanned Islanding or Emergency standby - Closed transition (with soft unload) or Open transition
- Load shed/load add - Automatic or manual load shed up to four (4) stages
- Planned Islanding or Intentional islanding
- Load sense/load demand - Based on asset priority or engine-hour balancing - Automatically matches on-line asset capacity to the loads
- Economy mode - All Gensets and non-renewable "fuel consuming" assets OFF
- Utility parallel, base load operations
- Pro-active add and drop - Ability to manually bring additional gensets online in anticipation of bringing on large loads - Manually turning off gensets instead of waiting for LSLD drop when the customer knows large loads are being taken offline
- Utility parallel, export power to grid - Target export setpoint is maintained
- Reliability mode - At least one high priority "fuel consuming" asset ON
- Scheduling - 5 schedules and 6 segments - BESS dispatch scheduling based on year, month, time, day and segment of day - 5 schedules and 6 segments -Import and export scheduling for active and reactive power based on time, day and segment of day
- 3 Flexible efficiency modes 1, 2 and 3 that may be set up based on asset group priorities
- Grid Reactive Control mode - There are 4 available reactive power control settings- Constant VAr, Constant PF, Volt-VAr curve, Watt-VAr curve
- Load smoothing mode - Non-stable load dispatch using available assets for specified durations of time
