Core Viewpoint - The energy supply for winter is entering a critical phase, with power companies across various regions accelerating key project construction, tapping into demand response potential, and strengthening inter-provincial and inter-regional cooperation to ensure electricity supply during the winter season [1] Group 1: Key Projects and Infrastructure - The Chengdu Airport 500 kV transformer project has been completed and put into operation, enhancing winter supply capacity for the Chengdu power grid, with a total capacity of 2.4 million kVA from two new main transformers [2] - In Hebei, a multi-faceted power supply system is being developed, including a 200 MW wind power project paired with a 40 MW/160 MWh energy storage system, which has already been operational [4] Group 2: Technological Innovations and Management - In Shandong, the introduction of smart technologies has improved power dispatching capabilities, utilizing big data for load analysis and real-time monitoring to ensure supply for essential services [5] - The virtual power plant concept is growing, with the Shanghai Electric Power's virtual power plant connecting 55 operators and aggregating a resource pool of 2.28 million kW, marking a 103% increase [6] Group 3: Cross-Regional Cooperation - Cross-provincial and inter-regional cooperation is increasingly important for winter power supply, with successful green electricity trading between Shanghai and Jiangsu, and the first inter-regional capacity support transaction reducing coal-fired power generation in Shanghai [7]

Core Viewpoint - The "Car and Network Interaction" event in Tianjin successfully demonstrated the potential of integrating electric vehicle charging with grid management, contributing to the stability of the power grid and promoting the development of green transportation [3][4]. Group 1: Event Overview - The "Car and Network Interaction Demonstration Month" in Tianjin concluded on October 18, organized by the Tianjin Development and Reform Commission and State Grid Tianjin Electric Power Company, achieving significant results in power grid management [3]. - The event aggregated over 50,000 charging piles and involved approximately 15,000 vehicle trips, resulting in a peak load reduction of about 320,000 kilowatt-hours and saving car owners around 160,000 yuan in charging costs [4]. Group 2: Technological Integration - The success of the event was supported by a two-level interactive control system between the power grid and electric vehicle charging operators, utilizing technologies such as virtual power plants [6]. - Tianjin has aggregated various adjustable resources, including charging stations and distributed photovoltaics, forming a virtual power plant with a capacity of 316 megawatts, enhancing the stability of the power grid [6]. Group 3: Industry Impact - The event is seen as a milestone in implementing national pilot tasks and constructing a new power system, exploring replicable experiences for broader application [3]. - The integration of electric vehicles as "mobile charging treasures" is transitioning from conceptual demonstration to large-scale application, contributing to the orderly charging during peak times and discharging during low-load periods [4].
