As PV penetration increases, the problem is exacerbated due to an increasing ramp rate that adds strain to the electricity grid. Another challenge is that the power profiles vary considerably by day and by season. We propose a system control algorithm using reinforcement learning for a battery-integrated PV converter system that works in real-time, is dynamic, and is adaptive. Results show a good balance among four objectives, which are verified by real data sets from Taiwan and Germany.Duck Curve | Energy Storage System | Machine Learning | Photovoltaic Power | Reinforcement Learning | Smart Grid | System Control Algorithm[SDGs]SDG7PV Inverter Control Algorithm Using Reinforcement Learning to Mitigate the Duck Curve Problemconference paper10.1109/APEC43580.2023.101314752-s2.0-85162257958https://api.elsevier.com/content/abstract/scopus_id/85162257958
