Abstract

Time Series Observation and Action Handling for Battery Management in Applying Deep Reinforcement Learning for Microgrid Energy Management / The transformation from traditional grids to microgrids introduces challenges due to multiple distributed energy resources and the intermittency of renewable energy sources and loads. Much effort has been committed to the design of microgrid energy management systems to attain optimal operation, and reinforcement learning is considered one of the most promising methods because of its competitive properties. Reinforcement learning algorithms generally do not assume precise models and can learn the underlying dynamics of the system under uncertainty by interacting with the environment. However, directly applying reinforcement learning to microgrid energy management is not an easy task. In this paper, we study two design aspects in reinforcement learning algorithms for microgrid energy management, which are related to time series observation and battery management in microgrids. In order to process time series data and handle varying battery charging/discharging bounds in our deep reinforcement learning algorithm, recurrent neural networks and valid action space mapping are used in our implementation. Experimental results confirm that the two design aspects are crucial for applying reinforcement learning in microgrid energy management.
