With the rapid development of smart grids, the secure transmission and storage of power data have become of vital importance. This paper proposes an image encryption algorithm for some smart grid images based on chaotic systems. The algorithm utilizes the high sensitivity and pseudo-randomness of chaotic systems, combined with image encryption technology, to construct an efficient and secure encryption scheme. Firstly, a 4D memristive Sprott K system is adopted to generate chaotic sequences as the encryption keystream. Secondly, through the dual encryption mechanism of scrambling and diffusion, the positions of image pixels are scrambled and their values are replaced to enhance the algorithm's anti-attack ability. The simulation results show that this algorithm exhibits superior performance in terms of key space, statistical characteristics, sensitivity, and resistance to differential attacks, and can effectively protect the security and privacy of smart grid images. In addition, this scheme has relatively low computational complexity and is suitable for real-time implementation.
