Abstract: Offshore wind energy, a cornerstone of sustainable power generation, faces escalating operational challenges as farms expand to harness cost efficiencies, including the imperative to counteract power fluctuations caused by wake effects and weather volatility. This study introduces a domain-informed Deep Q-Network (DQN) framework, engineered to optimize the allocation of maintenance resources and the strategic selection of maintenance tasks, resulting in an 11.1% increase in power generation compared to default wind conditions. By incorporating multiple wake model for enhanced decision-making accuracy, the scheduling dilemma is formulated as Markov Decision Processes (MDPs) to navigate the complexities of maintenance scheduling. A notable innovation is the integration of convolutional layers, which expedite algorithmic convergence. These results underscore the significant potential of our model to improve operational productivity in large-scale offshore wind farms.
