Reinforcement Learning (RL) is a promising approach to power network control (PNC) for optimizing power grid topologies.
The Learning To Run a Power Network (L2RPN) competitions have accelerated research in RL-based methods for power grid optimization.
This survey provides a comprehensive overview of RL applications for power grid topology optimization, categorizing existing techniques and highlighting key design choices.
The survey also presents a comparative study evaluating the practical effectiveness of commonly applied RL-based methods and identifies open research challenges.
