在本文中，我们首先展示了如何一般微电网可以建模为一个负反馈配置，包括两个子系统。第一个子系统是互联的微电网，其通过负反馈受到由所有单端口组件组成的第二个子系统的影响。这是通过将物理状态变量转换为能量状态变量，并通过系统地定义在这个转换后的状态空间中的系统组件的输入和输出来建模的。我们接下来利用这样的事实，即对于这种基本的反馈配置，存在几种类型的条件，关于子系统的属性，以确保整体系统的属性。特别是，我们利用耗散性理论提出了一个子系统的非线性控制设计异构资源组件，包括微电网，使他们共同导致在给定范围内的系统扰动的闭环可行和稳定的动态系统。
In this paper, we first show how general microgrid can be modeled as a negative feedback configuration comprising two subsystems. The first subsystem is the interconnected microgrid grid which is affected through negative feedback by the second subsystem consisting of all single-port components. This is modeled by transforming physical state variables into energy state variables and by systematically defining input and output of system components in this transformed state space. We next draw on the fact that for this basic feedback configuration there exist several types of conditions regarding subsystem properties which ensure overall system properties. In particular, we utilize dissipativity theory to propose a subsystem nonlinear control design for heterogeneous resource components comprising microgrids so that they jointly result in a closed-loop feasible and stable dynamical system for given ranges of system disturbances.
