With the large-scale integration of high-penetration distributed photovoltaics, wind power, and other renewable energy sources into distribution networks, the operational characteristics of distribution networks have become increasingly complex. Issues such as voltage fluctuations, power flow reversal, and power quality degradation have become increasingly prominent, threatening the secure operation of distribution networks. Traditional dispatching modes struggle to achieve precise perception and rapid regulation. There is an urgent need to construct an active distribution network technical system integrating "panoramic perception—intelligent decision-making—flexible regulation."

This sub-forum focuses on key technologies for panoramic perception and flexible regulation of active distribution networks under high-penetration renewable energy integration. It aims to explore how to enhance the hosting capacity and operational resilience of distribution networks through high-precision state perception, high-efficiency power flow analysis, and intelligent zoned regulation. Core topics include but are not limited to:

1. Panoramic state perception and high-precision state estimation for distribution networks

2. Power flow calculation and analysis for distribution networks adapting to renewable energy uncertainty

3. Autonomous and coordinated regulation of distribution networks based on cluster partitioning

4. Multi-time-scale flexible regulation and resource coordination

5. Adaptive partitioning of distribution networks under dynamic topology

6. Market-based dispatch and compensation mechanism design for distribution network reactive power resources

7. Adaptive control of distribution networks for photovoltaic fluctuations and dynamic loads

8. Demonstration cases and effectiveness evaluation of high-penetration renewable energy distribution network pilot zones
