The existing power system does not have a unified grid resource management model. The basic data of equipment assets cannot be stored, managed, and maintained in a unified manner. The production systems of different departments are developed by different manufacturers at different times, which leads to the problem of production data silos and high maintenance costs. To solve this problem, a grid resource business middle platform based on State grid-corporation public data model (SG-CIM, CIM) model is designed in this paper. Firstly, the concept and core technology of the middle platform in the power grid resource business are introduced. Then a dynamic data migration strategy based on the FA algorithm is proposed. Finally, the model based on SG-CIM and the application scenario of power transmission and distribution are built and its effectiveness is analyzed.

Blockchain technology is a new type of distributed database technology solution, which has unique advantages in terms of decentralization, security and transparency. These characteristics of the blockchain can solve some typical technical problems in the construction of the current power distribution IoT cloud master station. In this context, the architecture design and implementation of the power distribution IoT cloud master station based on blockchain is first discussed; then, the blockchain is integrated from three aspects: security performance, state estimation algorithm, and deep search engine. The new framework of the technology is analyzed. Finally, the application of the blockchain technology in the cloud master station of the distribution network is summarized.
