Overview of Key Technologies for Distributed Smart Grid in Parks and Rural Areas: A Case Study in China

With the proposal of the "dual carbon'' goal, distributed energy resources are widely used in carbon reduction and transformation in urban and rural areas of China. However, due to the characteristics of distributed energy generation, there are still some problems and challenges in its application. So far, few papers have commented on the new development obstacles and challenges of distributed smart grids. In order to clarify the characteristics, challenges, and future research prospects of distributed smart grids more clearly, this article first focuses on the real cases and characteristic analysis of distributed smart grids in rural and urban park scenarios in China. Next, the key analysis and control technologies that have been applied or can be applied to distributed smart grids in rural and park scenarios are summarized. Finally, a detailed discussion is conducted on the current issues, challenges, and future research directions of distributed smart grids in China in terms of stability, security, rural infrastructure, and consumption.
