In order to manage the electricity consumption information of microgrid users, the reliability of electricity information collection is studied in this paper. The normal communication between the acquisition terminal and the smart meter is a key factor affecting the accurate collection of power information; it is the basis for ensuring the operation of the microgrid as well. In order to improve the reliability of the low power line communication between the acquisition terminal and smart meters, this article first uses the (...) static networking method to layer the smart meters and select relays from them and then select the optimal communication path based on integrating communication quality and relay forwarding number dynamically, which could avoid the signal conflict problem caused by simultaneous communication. Finally, by analyzing the influence of the time-varying power line channel on the smart meter communication, a method based on the integrated communication quality and the relay number to consider the time variability of low power line communication is proposed. Choosing the optimal path of the smart meters when the communication path is abnormal can not only establish a new communication path for communication in time, but also avoid communication failures caused by the time-varying channel. Through MATLAB simulation, the time-varying dynamic network of the power line channel is introduced in this paper, which improves the reliability of the smart meter communication and has certain guiding significance for the actual smart meter network construction in microgrid.

In the treatise On the Spiritual in Art, Wassily Kandinsky divided the creation of art into three categories, the ultimate one of which is called Composition. In this article, I argue that Kandinsky’s classification is similar and comparable to the principle of semi-abstract Chinese freehand brushwork summarized by Zheng Xie in the Inscriptions on Painting - Bamboo. In an attempt to clarify the core of Kandinsky’s strategy of abstraction, i.e. the transformation from painting to writing, I then connect it with (...) the evolution of Chinese characters and the aesthetic theory of Chinese calligraphy, which is also in accord with Kandinsky’s idea of internal necessity and the spirit in art. Through this aesthetic dialogue across time and space, this article aims to bring a new dimension to the understanding of Western abstractionism from the perspective of the oriental philosophy of art.
