Patent Application for Grid Load Forecasting Technology Based on Privacy-Preserving Computation and Blockchain Granted

On November 28, 2024, the State Intellectual Property Office of China announced the publication of a patent application submitted by State Grid Information & Communication Industry Group Co., Ltd. The patent, titled "Grid Load Forecasting Method and Related Device Based on Privacy-Preserving Computation and Blockchain," has been published with publication number CN119029841A. The application date was July 2024. This publication signifies that a novel method combining privacy-preserving computation and blockchain technology for grid load forecasting is nearing application, promising significant improvements in the security and efficiency of future grid management and energy prediction.

The core of this patent application lies in a novel grid load forecasting method that cleverly integrates privacy-preserving computation and blockchain technology, effectively addressing privacy leakage and data security issues inherent in traditional methods. Traditional grid load forecasting requires centralized processing of large amounts of power data, posing significant data security risks. Data breaches could lead to severe economic losses or even power system failures. This patented method, however, employs privacy-preserving computation to encrypt power data, ensuring its encryption throughout transmission and processing, thereby effectively protecting data privacy.

The patent abstract details the method's steps: First, each participating platform node homomorphically encrypts the acquired power data, resulting in multiple ciphertext data. Homomorphic encryption allows computation on encrypted data without prior decryption, ensuring prediction accuracy while safeguarding data privacy. Then, any platform node can publish a load forecasting task on the blockchain. The blockchain's introduction guarantees transaction transparency and immutability, providing a secure and reliable platform for multi-party participation. After obtaining the ciphertext data from the node that published the task, other platform nodes use their trained load forecasting models to predict the ciphertext data, obtaining result ciphertexts, which are then submitted to the node that published the task. Finally, the publishing node decrypts the result ciphertexts to obtain the final decrypted load data.

This grid load forecasting method based on privacy-preserving computation and blockchain offers significant advantages over traditional methods. First, it effectively protects the privacy of power data, mitigating the risk of data breaches. Second, the application of blockchain technology ensures transparency and traceability of the prediction process, enhancing the credibility of the results. Third, the multi-node prediction model improves prediction accuracy and robustness, reducing the risk of single points of failure. Finally, the method is highly scalable and can be easily applied to grid systems of various sizes.

The successful publication of this patent application represents a major breakthrough for State Grid Information & Communication Industry Group Co., Ltd. in technological innovation and marks significant progress in China's grid load forecasting technology. Further research and application of this technology will effectively improve grid operational efficiency and safety, providing a solid foundation for building a more secure and reliable power system. Its applications extend beyond grid load forecasting; future possibilities include forecasting for other energy sources like wind and solar power, supporting the construction of a clean energy system.

The success of this patent application also highlights the importance the Chinese government places on technological innovation and intellectual property protection.
