光储微电网信息物理融合建模与仿真

Model and simulation of micro-grid PV-battery cyber-physical system

为了实现微电网智能化、高效化、信息化和安全化,将信息物理融合系统(Cyber-physical System,CPS)引入到微电网中。文中将公共信息模型概念与基于统一建模语言(Unified Modeling Language,UML)的设备相结合,通过分析信息模型和物理模型之间的内在联系,提出了两种模型的融合方法。针对智能微电网中光伏、储能以及光储协调控制组件进行基于信息物理的融合建模,重点分析了光伏和光储协调控制组件信息物理融合模型的仿真结果,验证了蓄电池SOC状态预测的准确性以及光储协调控制信息物理融合模型的有效性和稳定性。

In order to achieve the intelligence,high efficiency,information and security on micro-grid,the paper establishes cyber-physical system（CPS） which can improve the information and optimization control of the whole system network. The paper combines the concept of CIM with the equipment based on unified modeling Language technology,and proposes the method of model fusion by analyzing the internal relationship between the cyber model and physical model. Also,it focuses on the fusion modeling of photovoltaic,energy storage components and corresponding coordination control of intelligent microgrid. It analyzes the simulation of the fusion modeling of photovoltaic and PV-Battery coordination control of intelligent micro-grid, and proves the accuracy of prediction of the battery SOC status, the effectiveness and stabilization of PV-Battery cyber-physical model.
