Prediction and Decision Integrated Scheduling of Energy Storage System in Wind Farm Based on Deep Reinforcement Learning
The optimal control of the energy storage system (ESS) in the wind farm can improve the competitiveness of the wind farm
which is a power producer in the electricity market. In this paper
a prediction and decision integrated scheduling method of ESS of the wind farm is proposed based on deep reinforcement learning
in order to make the original high-dimensional measurement data of the wind farm directly drive the ESS. Compared with the traditional scheduling model that separates prediction and decision
the prediction and decision integrated scheduling model combines the wind power prediction and ESS operation decision together
to avoid the loss of effective decision-making information in the prediction period. Stochastic laws of wind power do not need to be artificially portrayed through mathematical assumptions and modeling errors are avoided. Then
Rainbow algorithm
a deep reinforcement learning algorithm
is introduced to optimize the end-to-end control strategy between the wind farm measurement data and the ESS operation instruction
which can dynamically coordinate multi-period system profits. Finally
by analyzing case studies based on the wind farm historical data
the superiority of the proposed integrated scheduling mode and the effectiveness of deep reinforcement learning in dealing with the uncertainty problems are verified.
