## Summary

In a modern power system that relies increasingly on renewable energy sources, accurate wind power forecasting is essential for effective power grid dispatching plans due to the volatile nature of wind power. However, traditional centralized forecasting methods raise concerns regarding data privacy and the problem of data islands. To address these challenges, this study proposes a novel approach called federated deep reinforcement learning (FedDRL) that combines federated learning and deep reinforcement learning (DRL) for ultra-short-term wind power forecasting. The paper first utilizes the deep deterministic policy gradient (DDPG) algorithm as the basic forecasting model to enhance prediction accuracy. Then, it integrates the DDPG forecasting model into the framework of federated learning. FedDRL enables the acquisition of an accurate prediction model in a decentralized manner by sharing model parameters instead of sharing private data, thereby avoiding sensitive privacy issues. Simulation results demonstrate that FedDRL outperforms traditional prediction methods in terms of forecasting accuracy. Moreover, while ensuring superior forecasting performance, FedDRL effectively safeguards data privacy and alleviates communication pressure compared to conventional centralized forecasting approaches. Additionally, a simulation with different federated learning parameters confirms the robustness of the proposed scheme. Overall, this research presents an innovative solution for wind power forecasting that addresses data privacy concerns through federated deep reinforcement learning. By combining these techniques, it achieves accurate predictions while protecting sensitive information and promoting decentralized collaboration in modern power systems with renewable energy sources.
