Multi-timescale optimization with energy storage in smart distribution grids

Dr. Raheel Zafar
Rapid increase in the integration of intermittent renewable energy sources into existing distribution grids has brought several technical challenges. In this talk, the speaker discusses the potential of multi-timescale volt/VAR optimization approach to coordinate slow-acting traditional volt/VAR control equipment with fast-acting smart inverters. This multi-timescale coordinated control scheme employing battery energy storage system can effectively integrate renewable sources in future distribution grids. The volt/VAR optimization is a mixed-integer nonlinear programming problem. It is NP-hard problem due to nonconvex equality constraints and integer variables. The speaker highlights the aims and results of his research work employing tractable convex relaxations such as semidefinite and mixed-integer second-order cone programs to find the global optimal solutions of several concrete problems.
