Energy Management Model and Dynamic Link Behavior Analysis Method for Multi-microgrid Systems Under Dynamic System of Systems Architecture

随着多微电网系统运行环境的不断变化,各子微电网将会动态地退出或加入多微电网系统中,导致多微电网系统的物理和信息链接发生动态变化,是影响多微电网协同优化的重大因素之一。针对多微电网动态链接行为下的协同优化问题,该文在引入体系(system of systems,SoS)方法构建多微电网So S架构以及动态交易链接矩阵的基础上,建立多微电网能量管理与贡献度评估模型,提出多微电网动态链接行为分析方法,定量分析不同动态链接行为对多微电网协同优化运行的影响。最后结合交替方向乘子法求解模型,通过仿真分析验证所建模型和分析方法的有效性。

With the change of the operating environment of the multi-microgrid system, the sub-microgrid dynamically exits or joins the multi-microgrid system. This behavior leads to changes of the physical and information links of the multi-microgrid system. Therefore, it is one of the major factors of optimization operation of multi-microgrid system. This paper introduced the system of systems(SoS) method to solve collaborative optimization problem of multi-microgrid system considering the dynamic behavior. Baesed on the SoS architecture and the proposed dynamic transaction matrix, energy management and contribution assessment model of multi-microgrid system were built. Moreover, the method for dynamic link behavior of multi-microgrid was biult to quantitatively analyze the impact of different dynamic link behaviors. Finally, the alternating direction multiplier method was used to solve the model. The effectiveness of the proposed model is verified by numerical cases.
