Hardware-in-the-loop Simulation Teaching System for Source-grid-load-storage Based on Hierarchical Decoupling Architecture

Under the "dual carbon" goal, the collaborative control of source, grid, load and storage has become the core of cultivating electric power talents. To address the problems of high software-hardware coupling, poor scenario adaptability and lack of a teaching evaluation system in existing simulation teaching systems, a semi-physical simulation teaching system for source, grid, load and storage based on a hierarchical decoupling architecture is designed. The system adopts a three-layer decoupling architecture of application, control and equipment layers, realizes closed-loop interaction between digital models and physical devices through standardized interfaces, builds an energy management strategy library for multiple teaching scenarios, develops a software platform integrating teaching demonstration, simulation operation, prediction analysis and training assessment, and establishes a multi-dimensional quantitative evaluation model, which solves the separation between theory and practice and provides standardized and scalable support for teaching practice of electrical engineering.
