Local Protection of Power Data Prediction Model Based on Federated Learning and Homomorphic Encryption

摘要: 电力数据的准确、快速预测不仅对电力系统的稳定、正常运行至关重要,也会对整个社会的生产生活产生重大影响.因此,高效、准确地预测电力数据是电力数据研究中的一项重要工作.循环神经网络在电力数据预测问题上具有优异的表现,但是需要大量数据来训练模型.各大电力公司出于隐私安全问题的考虑,并不愿意共享各自的电力数据,从而无法训练出更加精确的模型.此外,在海量数据上传到中央服务器对联合模型进行训练的过程中会产生巨大的网络资源开销.针对这些问题,将联邦学习与Paillier同态加密算法相结合,提出了基于联邦学习和同态加密的电力数据预测模型本地保护方法.实现了对电力数据和本地模型参数的保护,在安全的状态下对联合模型进行共同训练.使用真实的电力数据进行了实验,该方法取得了良好的实验结果.

Abstract: The accurate and rapid prediction of power data is not only crucial to the stability and  regular operation of the power system but also has a significant impact on the production and life of the entire society. Therefore, efficient and accurate prediction of power data is an essential work in power data research. Recurrent neural networks have excellent performance in power data prediction problems, but require a large amount of data to train the model. Due to privacy concerns, power companies are reluctant to share their electricity data, making it impossible to train more accurate models. In addition, colossal network resource overhead is incurred while uploading massive amounts of data to a central server to train the federated model. To address these problems, this paper combines federal learning with paillier homomorphic encryption algorithm and proposes a local protection method for power data prediction models based on federal learning and homomorphic encryption. It implements the protection of power data and local model parameters, and cotrains the joint model in a secure manner. We conducted experiments using accurate electricity data, and this method achieved good experimental results.
