The main advantage of a Microgrid and associated SCADA system, such as that at the CIT test bed, is that it permits experiments and allows investigations of cause & effect that would not typically be allowed on a live grid.
In a real grid, these may go undetected for long periods of time or may never be detected in some cases. For the CIT test bed, cyber attacks on the SCADA system could be enabled via a web interface.
Improve attack resilient control algorithms
Analyze cyber threats to the smart grid components Expand and provide local microgrid testbed for small scale test

NIMBUS microgrid An extensive network of meter and sensors has been deployed to facilitate measurement and data
collection necessary for the control of the electrical and thermal systems. Those measurements together with relevant information about gas and electricity power
consumption measurements and prices, as well as thermal/electrical loads and weather forecast (including wind), are available at all times from the SCADA and BMS systems and are used in the three-layer hierarchical control system.

BMS for Nimbus building heating system that implements the local controller algorithms for thermal system components. Figure shows the BMS HMI for boilers management and experimental temperature profiles over one week. [simple operation example where the boiler and mixing valve are scheduled to be active at 7am and off at 9pm and during the weekend (3/23/2013 and 3/24/2013) ]
