lPresentation Overview:

The transformation of the power industry towards the low-carbon sector has spurred a steady increase in the penetration level of distributed energy systems. In traditional power systems, large synchronous generators serve as the main power source. However, in the new generation of power systems with high penetration of distributed energy systems connected to the distribution network, these systems become the smallest power supply units in the system. The integration of large-scale distributed energy systems into the grid poses significant challenges to the grid but also presents opportunities. The flexible regulation potential of distributed energy systems, as a resource supporting the stable operation of the grid, is yet to be fully exploited. There are still opportunities and challenges in the integration, management, and control technologies of distributed energy systems in the grid. This presentation focuses on the latest developments in the development of distributed energy systems under the backdrop of power system transformation. It outlines the evolution of standards for the grid connection of distributed energy systems over the past 25 years to reveal the direction of relevant technological evolution.

Additionally, given the crucial role of power electronics technology in the integration, performance improvement, and grid operation support of distributed energy systems, the presentation introduces the promotion role of distributed energy systems in the development of power electronics technology, covering components, topologies, control, and grid-support functions of power converters. Some of the content in this presentation is derived from the relevant work and summary reports of the IEEE International Technology Roadmap for Distributed Energy Resources Power Electronics (ITRD).
