Mission Statements
• MAGTFTC: Manages the MAGTF Training Program (TP) and conducts service-level MAGTF combined arms training in order to enhance the combat readiness of the operating forces and support the Commandant of the Marine Corps’ responsibilities to national security.
• MCAGCC: Provides and manages facilities, service and support to forces and families permanently assigned or participating in training aboard the Combat Center in order to ensure readiness of the MAGTF as well as the welfare of personnel and families.
ESTCP/GE Demonstration
· 2 year, $2 million contract· MCAGCC is leading the Marine Corps and Navy in the
areas of energy efficiency and security· MCAGCC long range plan parallels scope· Most of the infrastructure required for an effective

Completed all the following new features of microgrid:
Optimal Dispatch of Distributed Energy Resources (DER) both during
grid-connected and islanded conditions – development complete
Dispatch capability of electrical and thermal assets - completed
Built-in hooks of future enhancements like new CHP, new PV and
energy storage (more things to optimize) - completed
Interface of GE equipment with Legacy Systems from JCI, Rockwell etc.
Testing in mixed type of communication media: wireless, Ethernet
Testing Mixed type of protocols: Modbus, Bacnet, RSLinx
Mixed mode of operations: Advisory, Automated, Manual and Legacy
Initial Building Energy Management interface using Cimplicity completed

Phase II – Integrated Volt/Var Control
Dynamic Programming (DP) based
Volt/VAR Control
● In each iteration, the control signals to cap-banks (on or off) is generated.
● Runs power flow and calculates the cost functions for all the possibilities
● Calculates the incremental benefit with the best solution and performs an iteration if the benefits is less than a preset minimum value.
● The least cost function solution is the best solution and used to set the optimal IVVC schedule of the cap-banks
● Typically the cost function is a combination or reduced grid import of VARs, reduced number of voltage violations and reduced losses in the cables
