Cat® Microgrid Master Controller-Small (MMC-S)

Asset Optimization

  • Configurations to optimize overall 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, charging batteries from PV only or maximizing system reliability. The system may also be configured to provide a minimum level of spinning reserve online to respond to sudden load transients.

Remote Monitoring

  • The option for remote monitoring offers complete system monitoring using Cat® Connect technology to provide real time performance and health of the installation.

Renewable Integration

  • The distributed energy resources, including the photovoltaic (PV) system, energy storage system (ESS) and generator sets are controlled from the MMC-S. The MMC-S will determine the correct energy contribution from each of the distributed energy resources to maximize penetration from renewable energy sources and system reliability.
