Abstract:
A microgrid can be defined as a low voltage distribution network comprising various DGs, storage devices, and responsive loads that can be operated in both grid-connected and islanded modes. Microgrid improves local reliability of energy supply, reduces emissions and contributes to lower cost of energy supply by taking advantage of distributed energy resources (DERs), storage devices and responsive loads. In order to achieve these benefits and supply energy in a reliable and economic way, multiple DERs, storage devices and responsive loads within the microgrid must be operated in a coordinated and coherent fashion. To that end, a microgrid design tool, Microgrid Assisted Design for Remote Areas (MADRA) was developed for the optimal siting at sizing of generation and storage. Then, a microgrid controller, Complete System-Level Efficient and Interoperable Solution for Microgrid Integrated Controls (CSEISMIC) was designed for the secure and economic operation of the microgrid. Various parts of CSEISMIC including SCADA, EMS, various device controllers and real world demonstrations will be introduced.
Bio:
Guodong Liu received his Ph.D. degree in electric power engineering from the University of Tennessee, Knoxville in 2014. He has been working as Post-doctorate Research Associate (2014-2015) and R&D Staff (2015-present) in the Grid Components and Controls group of Oak Ridge National Laboratory (ORNL). Currently he leads projects on Microgrid planning and operation, renewable energy integration and active distribution network management. He was the major developer of CSEISMIC microgrid controller, DECC microgrid testbed and Microgrid Assisted Design for Remote Areas (MADRA) sponsored by the DOE. His research interests include power system operation and planning, power system reliability and resiliency assessment, distributed energy resource and microgrids. He is an IEEE senior member and twice winner of the IEEE PES General Meeting best paper award. He has published more than 60 peer-reviewed journals and conference papers.
