The Power Carbon Neutrality Sub-Forum, a significant component of the 2023 China Energy Internet Conference, was successfully organized by Tsinghua University and the National Energy Internet Industry and Technology Innovation Alliance. The conference, held in Shanghai, focused on the theme "Addressing the Dual Control Challenge of Carbon Emissions, Constructing a New Energy System" and actively responded to new opportunities and challenges in developing the energy internet to achieve dual carbon goals, building a new power system, and constructing a new energy system. The event unfolded in the format of a main summit plus eight major sub-forums.
In the afternoon of October 26, the Power Carbon Neutrality Sub-Forum, themed "Breakthroughs in Major Theories and Applications in the Field of Power Carbon Neutrality," aimed to implement the important deployment of actively and steadily promoting carbon peaking, carbon neutrality, and "accelerating the planning and construction of a new energy system," as outlined in the 20th CPC National Congress report. The sub-forum was chaired by Professor Xia Qing, Director of the Power Carbon Neutrality Special Committee of the China Energy Internet Industry Alliance (CEIA). Professor Xia Qing introduced the background of the establishment of the Power Carbon Neutrality Special Committee and the theme of this sub-forum, emphasizing that adapting the institutional mechanisms for high penetration of renewable energy consumption is a crucial support for realizing the dual carbon strategy.

In the thematic report segment, Tan Zhenfei, Assistant Researcher and Postdoctoral Fellow from the Department of Electrical Engineering at Shanghai Jiao Tong University, delivered a presentation titled "Analyzing New Theories and Methods of Load Behavior Using Holistic-Reduction Thinking." Addressing the challenges posed by the large-scale integration of fluctuating new energy sources and the rapid growth of emerging loads, Tan's presentation proposed a holistic-reduction integrated load behavior modeling theory. This theory breaks through application challenges in load modeling, making it interpretable, deducible, interactive, and embeddable. Tan introduced the embedded solution method for load behavior modeling and optimization problems, achieving precise coordination decisions for load flexible response, power system optimization scheduling, and electric power trading strategies. This method also provides technical support for the efficient aggregation and interaction of load-flexible resources.

Wang Jianxiao, Assistant Researcher at Peking University, shared insights on "New Theories and Methods for Optimizing Electric Power Systems Driven by Digital and Analytical Coupling." Against the backdrop of supporting the construction of new power systems with digital and intelligent grids, Wang addressed optimization challenges brought about by irrational market entities, complex operating modes, non-convexity of safety and stability, and fuzzy models in the scenarios of new power systems. Drawing inspiration from simulation methods used in the Eastern Interconnection and Western Interconnection in the United States, Wang proposed an efficient and accurate optimization method driven by digital and analytical coupling. This method comprehensively considers steady-state and dynamic operation constraints, digital power system-source-grid-load interaction, providing a new solution approach, theory, and method under high penetration of new energy.

Yang Shihai, Deputy Chief Engineer of the Marketing Service Center at State Grid Jiangsu Power Company, presented on "Perception, Measurement, and Active Response of New Power System Demand-Side Resources." Using the IEC white paper's definition of demand-side resources as a starting point, Yang proposed new measurement approaches (complementary intervention, data-mechanism fusion, individual-unit parallel usage) and flexible control methods (overall high reliability, individual fault tolerance) for new user-side loads with diverse characteristics of source, grid, load, and storage. These measures actively respond to demand-side resources, providing critical technical support for source-grid-load interaction.

Wang Wei, a first-level staff member at State Grid Shanghai Power Company, shared insights on "Shanghai's Virtual Power Plant Embarks on a New Journey—Key Support for Achieving Carbon Neutrality." Wang systematically reviewed the development status and features of typical virtual power plants in developed countries such as Australia, the United Kingdom, and Germany. Addressing challenges brought by the randomness of new energy and load fluctuations due to extreme weather, virtual power plants have achieved supply-demand matching and flexible operation of new power systems. In 2023, State Grid Shanghai Power Company, fulfilling its central enterprise responsibility, actively advanced the operational system's in-depth application of Shanghai's virtual power plant in aspects such as market construction, resource expansion, standard formulation, and safety protection. Twenty-two virtual power plant operators actively integrated into market operations, doubling adjustable capacity, effectively enriching power system supply guarantees, serving as a typical demonstration of constructing new power systems under carbon neutrality conditions.

In the final keynote presentation, Professor Xia Qing from the Department of Electrical Engineering at Tsinghua University, and the Director of the Power Carbon Neutrality Special Committee, delivered a presentation titled "Reshaping the Market Mechanism to Incentivize the Innovative Development of Green and Low-Carbon Technologies in the Power Market." Professor Xia first outlined the current challenges faced by the power market mechanism, including the contradiction between the running cost and marginal electricity price, the asymmetry between medium- and long-term and spot prices, and the lack of market models supporting new energy. He then shared the reform trends in power markets with high proportions of new energy in the United States, Australia, Europe, and other regions. Finally, he proposed the direction of power market mechanism reform to incentivize the innovative development of green and low-carbon technologies, sparking enthusiastic discussions and profound reflections among the audience.
