Xiangyu Zhang joined the Complex System Simulation and Optimization Group within the Computational Science Center at NREL in February 2019. At NREL, Xiangyu’s main research interest focuses on using optimization techniques and high-performance computing to improve the policy search in deep reinforcement learning (RL). The overarching objective is to enable training of reliable RL controllers for emerging stochastic nonlinear control problems in the energy systems in an efficient, practical, and cost-effective manner.

Before joining NREL, Xiangyu received his doctorate from Virginia Tech where he conducted research on cost-effective, intelligent building-grid integrated control via Internet-of-Things technologies. Even before that, he studied the mechanism, prevention, and mitigation of power system cascading failure/blackout at Tsinghua University.
