Abstract
The integration of distributed energy in smart grids is of great significance for enhancing the flexibility and sustainability of power systems. However, it also poses challenges to system stability. This paper explores how the integration of distributed energy affects the stability of smart grids, and analyzes the existing technical bottlenecks and solutions. Through case studies and simulation models, it demonstrates the phenomena such as dynamic balance problems, voltage fluctuations, and frequency deviations that may occur after different types of distributed energy resources (DERs) are connected to the grid. By optimizing control strategies and introducing advanced energy storage technologies, the negative impacts of distributed energy integration on system stability can be effectively mitigated, promoting the safe and efficient operation of smart grids.
Key words: Distributed Energy; Smart Grid; System Stability; Optimal Control
