摘要
针对大规模分布式光伏并网系统CPS联合仿真问题进行研究,提出一种基于状态缓存的同步方法,可使连续系统仿真与离散事件仿真准确同步,通过状态缓存和仿真回溯机制,在保证仿真准确性的同时有效提高效率。基于该同步方法,结合Matlab和OPNET,搭建联合仿真平台,并通过构造边界节点,可实现电力节点与通信节点的映射。仿真结果证明了该平台功能的有效性和计算的准确性,通过与其他平台的对比,体现了该平台在计算效率上的优势。
This paper addresses the co-simulation challenges of large-scale distributed photovoltaic(PV)grid-connected systems in the context of cyber-physical systems(CPS).A state-caching-based synchronization method is proposed,enabling precise synchronization between continuous system simulation and discrete event simulation.By incorporating state caching and a simulation rollback mechanism,this method achieves a balance between simulation accuracy and efficiency.Based on the proposed synchronization strategy,a co-simulation platform is constructed by integrating Matlab and OPNET.Through the design of boundary nodes,the mapping between power system nodes and communication nodes is effectively implemented.Simulation results validate the functionality of the platform and confirm the accuracy of the computations.Furthermore,comparative analyses demonstrate the platform’s superior computational efficiency compared to other co-simulation platforms.
