2. Overview
Use a combination of simulation and hardware to develop, study, and prove out methods for
Agent-moderated power control for MVDC systems
Converter-based circuit protection and power routing
Stability and control of two-shaft high-speed turbine generator/rectifier supplying power to dc bus, including paralleling, splitting, start-up, shut-down scenarios
Characterizing and controlling power quality in a dc environment
Design and control of dc/dc converters incorporating hf isolation transformers
Effectively integrating distributed energy storage with methods for fault protection, power quality, and agent-based power routing
Provide hardware modules that can be integrated into CAPS test bed and NSWC IFTP system

3. Hardware Strategy
USC hardware facility is being built around network of five AMSC PM1000 power modules
Power modules use versatile controllers “ginn’ed up” at MSU that serve as test beds for agent-moderated power control and for dynamic reprogramming of power modules
Hardware integrates with VTB Pro RT as a means for PHIL experiments, programming the PEBBs to represent arbitrary collections of load equipment
Intelligent load (or source) zone(s) will be developed to be inserted into MVDC context at CAPS laboratory, and/or on IFTP at NSWC

4. USC simulation facility is primarily based on VTB Pro
Simulation Strategy
USC simulation facility is primarily based on VTB Pro
Permits execution of control agents within the simulation context
Real time environment based on automatic code generation from simulation model (and soft RT in Windows environment)
Power controller programming is also based on automatic code generation from simulation model
Working towards HPC based on cluster computing, using several protocols for decoupling of power network and several protocols for communication between processors
