邻接矩阵
在图论和計算機科學中,邻接矩阵（英語： adjacency matrix ）是一種方阵,用來表示有限图。它的每個元素代表各点之间是否有边相连。 作爲特例,簡單圖的鄰接矩陣是(0,1)矩陣並且對角線元素都爲0。無向圖的鄰接矩陣是對稱矩陣。

Abstract: This paper presents four centrality measurements applied to an alternating current (AC) microgrid (MG) modeled as a multiplex network. The MG secondary control is separated into a
6 FAQs about [Microgrid adjacency matrix]
How can distributed cooperative control improve the reliability of microgrids?
The requirements for a central controller and complex communication networks reduce the system reliability. More reliable and sparse communication networks can be accommodated by applying distributed cooperative control to the design of secondary control for microgrids.
How is secondary control of electric power microgrids implemented?
The secondary control of electric power microgrids is implemented through the concept of distributed cooperative control of multi-agent systems. The Lyapunov energy-based technique is adopted to derive fully distributed voltage and frequency control protocols for each DG.
What is secondary voltage and frequency control of microgrids?
The secondary voltage and frequency control of microgrids are designed based on the distributed cooperative control of multi-agent systems. The microgrid is considered as a multi-agent system with DGs as its agents. DGs can communicate with each other through a communication network modelled by a digraph.
What is the control structure of microgrids?
The third layer is responsible for the economic dispatch, and optimises the generation of synchronous generators based on their operating costs [24, 25]. Similarly, the hierarchical control structure of microgrids consists of three control levels, namely, primary, secondary and tertiary control levels.
Which microgrid is used to verify the effectiveness of secondary control?
The microgrid shown in Fig. 4b is used to verify the effectiveness of the proposed secondary control. This microgrid consists of four DGs. The lines between buses are modelled as series RL branches. The specifications of the DGs, lines, and loads are summarised in Table 1.
What are the control gains of a microgrid?
The control gains cv, cω, and cp in (12), (28), and (34) are all set to 400. It is assumed that the microgrid is islanded form the main grid at t = 0. As seen in Fig. 7, after islanding, the direct term of the DG output voltages vodi and the DG terminal voltage amplitudes vo,magi go to different values less than vref.
