MMCP Microgrid Master Control Panel

Microgrid Controller for Reliable, Efficient, Sustainable Energy Systems in Tomorrows Low and Medium Voltage Facilities

APTView SCADA Control Panel HMI

The Microgrid Master Control Panel (MMCP) is a controller that provides real time integrated control of power production and power consumption for large scale (500kW – 50 MW) microgrids. This involves the aggregation of control for various distributed energy resources (DER) in both grid-connected and grid-isolated modes of operation, instantaneous load matching, and active control of microgrid stability. MMCP provides optimization of use of the diverse DER in various modes of operation, as well as automatic islanding and active synchronized re-connection of the microgrid loads to the utility power grid. 

Available in NEMA 1 indoor or NEMA 3R outdoor construction.

DER and Energy Storage technologies supported:

  • Natural gas reciprocating engines
  • Natural gas turbines
  • Bio-gas and Landfill gas reciprocating engines
  • Bio-gas and Landfill gas turbines
  • Micro-turbines
  • Battery storage
  • Solar PV array generation
  • Fuel cell generated power
  • Hydro power
  • Wind
  • Battery Storage Driven Generators
  • Other less common DER and Energy Storage such as combined cycle steam generators, flywheel, geothermal, etc.

Functions & Features

  • kW and KVAR control of DER load to achieve Microgrid system stability by matching the site active and reactive loads with DER active and reactive power production.
  • Optimization of utilization of various DER in grid connected and grid isolated modes of operation to achieve optimal balance between the efficiency and reliability of power delivery.
  • Control and optimization of spinning reserve as required for each mode of operation
  • Bumpless synchronous load transfer between the DER and Utility Grid.
  • Minimizing the diesel generators fuel consumption, while ensuring the microgrid system stability when operating in emergency standby mode of operation. Emergency operation time can be extended as much as 6 times with the same amount of on-site fuel storage.
  • Peak shaving and renewable DER power production peak shifting control for Load Demand Management.
  • Load shed, load add and bus load optimization control.
  • Grid frequency and voltage support control
  • SCADA interface
