Real-time Demonstrations

BESS control and protection system demonstrated through peer to peer communication (Eaton \& Cisco collaboration):

• Demonstrated as a part of edge-computing demonstrations in utility broadband alliance (UBBA) plugfest 2024.
• Proof of concept concencus based control system development for BESS featuring CL-7 voltage regulator, BESS, and CBC8000 capbank controller.
• Power and system modeling done in Typhoon HIL.
• Peer to peer communication achieved by utilizing Cisco hardware.
• Full video available here: Youtube Link.

PMU Pre-compliance test-suite:

• A test-infrastructure is proposed that uses low-voltage signals to validate the functionalities of a PMU under test. The test infrastructure is based on National Instruments’ cRIO hardware.
• The test-hardware can be easily controlled by a user from the GUI-based software designed in LabVIEW.
• A prototype PMU is put under the tests (using our test-suite) and its performance is analyzed and compared with the others available in literature.
• Possible adjustments of the test-suit on hardware and software ends are proposed.
• Demonstrated in: Congressional visit in 2021, IEEE Colloquium 2021

Networking experiments on Khorjin based synchrophasor synchornization gateway:

• cRIO based HW-SW setup to parse, synchronize, timestamp, and display multiple C37.118 streams.
• The PMU streams are corrupted with external networking hardware.
• The network is tampered with delay, data-drip and jitter to test its resillience.
• Demonstrated in: NASPI Meeting 2019

GFOV investigation in RT for DERs:

• Investigates the presence and effect of Ground Fault Overvoltage (GFOV) phenomenon in Grid-Connected PV inverters.
• Examines whether conventional neutral grounding, which eliminates this GFOV issue in synchronous generators- are necessary for inverter-based systems.
• Tests the effectiveness of SPOV mechanism against GFOV and LROV.
• Demonstrated in: Congressional visit in 2021, IEEE Colloquium 2021

SSGC based resillient networked-control for BESS:

• Implementation of a synchrophasor synchronization gateway and control (SSGC) hardware based on cRIO and Khorjin library.
• SSGC houses the secondary control functionalities for BESS which runs in a microgrid simulated in Typhoon HIL 604.
• The network for the PMU placed at BESS is attacked with external hardware.
• Network delay, data-drops and jitters were injected in the network to test the robustness of the control-network.
• An LPF was incorporated to get rid of all high frequency components of the control signal, to protect the Li-ion battery.
• Demonstrated in: Congressional visit in 2021
