What is a Microgrid?

Utility (optional)

Problem

Microgrids require precise orchestration of power sources

Utility (optional)

15

Universal Microgrid ControllerTM(Hybrid System Supervisory Controller)

• Monitors and coordinates the operation of all system components

• Touchscreen local operator interface

• On-board datalogging• Internet ready • Modular software –

modules pre-coded to enable use with all major models of wind turbine and diesel generator controllers.

Secondary Load Controller

• Diverts excess wind power to an electric boiler in the diesel plant heat recovery loop.

• Zero-crossing solid state switching → no harmonics

• Power control or frequency control

• Fast response – (3 msec)• Easily scalable

Synchronous Condenser

• Standalone or diesel-parallel operation

• Assists diesels (or inverter) in meeting reactive power demand

• Regulates voltage in standalone mode

• Magnetic “mass” provides additional voltage stiffness

• Rotating mass provides additional frequency stiffness

• Provides fault clearing current
