User Interface
- Provides graphical human machine interface (HMI) to all control elements to simplify operator interactions with DER assets. Includes system visualization and user interface for manual or automatic control of the DERs.
Distributed Energy Resources (DER) Dispatch
- Energy contribution from each of the DERs to maximize penetration from renewable energy sources and system reliability. Priority for distributed resource use can be changed from the Cat ECS 400 user interface.
- Optimizing asset performance according to pre-programmed routines that can be adjusted via user-selectable criteria. The optimization routines can be based on several different parameters, such as minimizing fuel cost, optimizing engine operation, user configurable schedules for charging and discharging and grid export/import, charging batteries from PV only or maximizing system reliability.
Grid Import/Export Control
- The Cat ECS 400 will regulate the amount of real and reactive power exported from DER's to the utility based on a programmable set point.
Cat Engineering Services Custom Solutions
- The Cat ECS provides the option to have Cat Engineering Services customize solutions to meet large site requirements worldwide.

Control Modes | Auto | Grid Connected - Sub-modes (16):
- Unplanned Islanding or Emergency standby - Closed transition (with soft unload) or Open transition
- 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
- Load shed/load add - Automatic or manual load shed up to eight (8) stages
- Utility parallel, import power from grid - Minimum import kW setpoint is maintained
- Utility parallel, export power to grid -Target export setpoint is maintained
- Utility parallel, base load operations
- Economy mode - All Gensets and non-renewable "fuel consuming" assets OFF
- 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
- Load smoothing mode - Non-stable load dispatch using available assets for specified durations of time
- 3 Flexible efficiency modes 1, 2 and 3 that may be set up based on asset group priorities
- 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
- Grid Reactive Control mode - There are 4 available reactive power control settings - Constant VAr, Constant PF, Volt-VAr curve, Watt-VAr curve.
Control Modes | Auto | Off-Grid (Island) - Sub-modes (7):
- 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
Control Modes | Manual |
- Communications, power allocation test mode for site commissioning. Manually control assets and the microgrid system.
Control Modes | Idle |
- Monitoring only - Cat ECS 400 relinquish control to another site controller.
Control Modes | Off |
- Off
