Abstract

Synchronization is a prerequisite for the stability of electrical energy, which is the cornerstone of a functioning society. Identifying whether generators are synchronized or not has been attracting immense research interest. Utilizing synchronized stability boundaries can strongly simplify stability discrimination. However, fundamental issues such as determining accurate stability boundaries remain challenging. In this study, an accurate synchronized stability boundary equation that is independent of the system and disturbances is presented, and it is applicable to an arbitrarily coupled grid. The special structure induced by spontaneous synchronization appears to be only near the stability boundary. The results of this study show that: the synchronous stability boundary is an intrinsic property of the system, independent of its structure and parameters. Synchronization on the network may be independent of the network. These conclusions will challenge the traditional perception of synchronization on networks, and the synchronization stability of the grid can be analyzed in a uniform way.

Commenter's Conflict of Interests: Author

Comment: The article in the PDF file was different from the earlier uploaded word document, e.g., the images were in the wrong place and the figures were separated from some of the legends. These errors are mainly found in figures 1,2,3,4. I thought this might confuse the logic of the article and greatly reduce its readability.Upload the manuscript again to correct these errors.
