A Prescriptive Dirichlet Power Allocation Policy with Deep Reinforcement Learning

no code implementations20 Jan 2022 Yuan Tian, Minghao Han, Chetan Kulkarni, Olga Fink

Moreover, we demonstrate the applicability of the proposed algorithm on a prescriptive operation case, where we propose the Dirichlet power allocation policy and evaluate the performance on a case study of a set of multiple lithium-ion (Li-I) battery systems.
