Abstract

Abstract:

Aiming for $“$ carbon peak $”$ and $“$ carbon neutrality $”$ ,the energy sector is undergoing significant reform. To address energy flow and planning optimization in integrated energy systems, a comprehensive simulation platform is developed. This platform combines physical and digital simulations with real-world validation and is modular in design, It includes an integrated energy model library, energy flow optimization, modeling management, real-time simulation, and energy monitoring. The platform enhances system safety, stability, and economic efficiency, While also improving planning and energy management. The paper analyzes the platform′s functional and physical architecture, introduces key modules, establishes dynamic and steady-state model libraries, and optimizes energy flow using multi-objective particle swarm optimization. Simulations conducted for typical campus scenarios validate the system model′s effectiveness.

Key words: integrated energy, digital-physical hybrid, simulation platform, energy flow optimization, communication interface, online access
