Splitting and Modularized Combination Approach of Power Distribution Terminal Services for Microservices Architecture

Aiming at the challenges of tightly coupled and difficult-to-change business applications of power information terminals of new power systems, this chapter proposes a microservice-oriented business disassembly and combination method for power distribution terminals. First, the electric power business organization process is portrayed in the form of electric power functional components by business, and the levels and types of electric power functional components are modeled to give the electric power business decomposition model. Then, the coupling model between functional components and component attributes is established, and based on which, the power business splitting constraints, power functional component performance evaluation indexes are given, and the business splitting is completed. At the same time, the open architecture is used to combine the functional components into modules with higher hierarchical granularity, and changes in the business requirements are localized to the specific modules to save development cost and cycle time, and to improve the scalability of the business applications. Finally, we analyze the impact of the splitting scheme and modular combination strategy on the coupling and scalability of electric power business applications through examples, and compare the solving effects of different architectures, so as to provide means and basis for analyzing the reasonable construction of organizational splitting and modular combination of electric power distribution terminal business.
