About the event

Energy Systems Innovation Center FA21 Seminar Series presents Recent Advances in Mixed-Integer Distribution Grid Optimal Power Flow (DOPF) Modelling and Applications by Dr. Sumit Paudyal.

Distribution grid optimal power flow (DOPF) problem for unbalanced systems are extensively explored in the literature as the number of controllable assets (e.g., flexible loads and distributed energy recourses) are increasing in power distribution grids. However, a large body of work does not consider modeling of legacy grid control devices, i.e., on-load tap changers (OLTC) and capacitor banks, in DOPF as this control equipment introduce integer variables in the DOPF models leading to mixed-integer formulations. Optimal control of legacy grid devices is essential for various grid applications including Volt/VAr control; however, conventional mixed-integer non-linear programming (MINLP) formulation of DOPF does not scale up for large grids. This technical talk presents state-of-the-art methods in handling DOPF problem with integer decision variables using mixed-integer linear and convex formulations, and discusses the efficacy and scalability of the DOPF models in managing Volt/VAr in a large-scale three-phase (2500+ node) distribution feeder.

Dr. Sumit Paudyal is Eminent Scholar Chaired Associate Professor in the Department of Electrical and Computer Engineering at Florida International University. Dr. Paudyal received MS in Electrical Engineering from the University of Saskatchewan, Canada in 2008, and PhD in Electrical Engineering from the University of Waterloo, Canada in 2012.
