Research Outcome


  • A micro-PMU measures the time-synchronized magnitude and phase angle of distribution grid voltage and current.
  • A micro-PMU generally offers higher accuracy (TVE < 0.01%) and a high reporting rate (120 measurement reports per second) compared to transmission grade PMU.
  • Accurate data from micro-PMU enable system analytics to determine the exact sequence of events that have led to islands or a major blackout.
  • First Indigenous joint development of ADMS is under progress by IIT Kanpur with Synergy Systems & Solutions (Industry Partner). ADMS is using the existing SCADA system and Meter Data Management System on Enterprise Service Bus (ESB). Existing IIT Kanpur network modelling is done in IEC (Common Interface Model) CIM along with GIS mapping using open-source platform OpenStreetMaps. Different algorithms such as load flow, State Estimation, Volt-Var optimization algorithms for the IIT Kanpur network are implemented and some are under testing. ADMS development has been panned in such a way where algorithms can be tested on the platform in plug and play mode.Integration of microgrid and storage controllers with existing SCADA (pilot testbeds) is under progress.
  • MIT and IITD have been working to extend the design of the retail market to include interactions of the DSO and TSO, and further develop the interactions between the DSO and WEM. The development of an iterative TSO-DSO clearing methodology is in the works, whereby the TSO oversees the LMP 24 calculation and treats the DSO as a constant load/generator per iteration, and the DSO optimally schedules the DERs within its network to update the power to be consumed/generated. By negotiating directly with the TSO, the TSO has better forecasts of load or generations (as the DSO is carrying this out), and the behind-the-meter DERs will be leveraged to provide system flexibility and reduce overall costs to the TSO.
  • WSU and IITK team worked collaboratively to build federated co-simulation testbed by leveraging geographically distributed laboratory facilities in USA and India. This setup was used to test and validate the large system fault response with DERs. Analyzed the effect of data rate on the accuracy of the power measurements at the connection of the two test systems and finding the effective data rate for co-simulation. Models were considered with BESS and Solar PV and exchanged between IITK and WSU. US-India federated Testbed was the first of a kind testbed where data is transferred at such a large distance, and it studied the performance of the co-simulation with respect to the data rate. In this testbed setup, transmission and distribution systems were simulated in RTDS placed at two different geographical locations.
  • WSU, WVU, and IITR collaborated in developing the federated cyber-physical simulation testbed to validate various control and cyber resilient approaches for microgrids connected distribution systems.
  • Benchmarking rural feeder and semi-urban pilot models developed by IITK team have been tested at WSU for validating the different research and development outcomes utilizing synthetic benchmark platform.
  • IITK rural benchmark has been co-modeled in ETAP, Gridlab-D, and OpenDSS software for cross validation. A comparison of results in different software has been performed by joint team members.
  • Rural benchmark model and simulation results are being reviewed and validated by an IEEE PES subcommittee to allow it to be published as an IEEE PES benchmark microgrid model. The approval the process is in progress and will be formally announced soon.
  • Expert Lectures and Tutorials were conducted as a part of the National Power Systems Conference in IIT Gandhinagar (17-19 December 2020), Power Electronics Drives and Energy System (PEDES) 16-19 December 2020 Jaipur, PES General Meeting 2020 and India Smart Utility Week 2021 (March 3-5, 2021), National Power system conference in IIT Delhi 2022 (17-19 December).
  • US researchers lead several panels at the IEEE PES General Meetings and other prestigious conferences over the last three years that included UI-ASSIST India and US speakers.
  • UI-ASSIST continued its monthly webinars during the academic year including presentations by India and US partners varying different topics from individual partner capabilities and facilities updates to theme research progress to India/US collaboration research updates.
  • Representatives from the US and India communications teams began weekly meetings to discuss updating the website to include all available public reports, publication references, and other links.
