With the large-scale integration of distributed energy resources, distribution systems have evolved from traditional unidirectional networks into complex multi-agent interactive systems. Various market participants including distributed generators, energy storage operators, and load aggregators engage in strategic gaming based on their individual interests. This creates significant challenges: conflicting interests and information asymmetry among participants, inadequacy of traditional centralized control in coordinating multiple stakeholders, and increased system complexity and uncertainty. The key challenge is achieving balanced participant interests through effective gaming mechanisms while ensuring safe and stable system operation.	· Data-intense next-generation distribution system · Adaptive operation and decision of distribution system · Multi-agent game theory in the application of distribution system · The configuration and control of flexibility assets in distribution system

Special Session 4: Power Quality Issues in High-Penetration Renewable Energy Power Systems (专题4：高比例新能源电力系统的电能质量问题)

Chair: Yi Zhang, Fuzhou University, China

Vice Chair: Yongfeng Zhang, Jinan University, China

Against the background of global energy low-carbon transformation, the high proportion of new energy access is promoting the transformation of the power system from the traditional "source with load" mode to the "source-network-load-storage" coordinated operation. This change brings new characteristics to the system. The difficulty of time-space matching between power supply and demand increases. The differences in dynamic characteristics of the power supply, power grid, and load lead to mutual influences of fluctuations at different time scales. These fluctuations cause power quality problems such as voltage deviation, flicker, and harmonics. The addition of new energy storage technology further increases the complexity of the system. At present, the multi-energy coordinated regulation ability is insufficient. The electricity-carbon market mechanism has not been effectively integrated. The overall supply-demand balance of the system continues to face pressure. Traditional governance methods have problems such as slow response speed, limited model accuracy, and imperfect evaluation of system adaptability. Existing equipment can hardly meet the requirements of the new system. It is urgent to conduct research on accurate power quality analysis methods, develop highly adaptive governance equipment, and explore comprehensive optimization schemes that combine multi-energy coordination with the electricity-carbon market.

Chair: Lei Chen, Wuhan University, China

Vice Chair: Cancan Rong, China University of Mining and Technology, China

The global pursuit of "dual carbon" goals and the accelerating transition toward renewable energy have propelled the widespread deployment of variable renewable energy sources (RES) such as wind and solar power. Concurrently, breakthroughs in grid-forming energy storage (GFES) technologies have unlocked unprecedented opportunities for stabilizing modern power systems. GFES, as a cornerstone technology enabling dynamic grid support and renewable energy integration, is emerging as a critical enabler for power system resilience, operational flexibility, and economic efficiency. GFES serves as a pivotal component in both transmission and distribution networks. For bulk power systems, the planning and operation of GFES must address the stability, reliability, and economic challenges posed by high-penetration renewable generation. Simultaneously, the deployment and control of GFES are constrained by grid topology and operational requirements. For renewable energy plants, GFES control strategies and capacity configuration significantly influence the spatiotemporal characteristics of power injection, which in turn affects overall system performance. However, the large-scale integration of intermittent renewables and GFES introduces new complexities in system dynamics, creating substantial challenges for power system planning, operation, and control. In this context, developing advanced GFES-based solutions for renewable power systems is of paramount importance for achieving carbon neutrality goals while ensuring grid security and stability. This Special Session aims to explore cutting-edge research on construction and control technologies for renewable power systems based on GFES, and to discuss the challenges, opportunities, and future trends in this field.
