Deepening Urban Adjustable Resources to Enhance Grid Resilience

The core competitiveness lies in the efficient aggregation of dispersed adjustable resources within cities, which serves as a critical pathway to improve grid resilience. In commercial buildings and industrial parks, the installation of ​smart control devices​ transforms air conditioning loads from "passive energy consumers" into "active regulating sources," with an estimated adjustable capacity contribution of ​800,000 kW by 2027. In the realm of charging and swapping stations, the promotion of ​Vehicle-to-Grid (V2G) technology​ enables electric vehicles (EVs) to store energy during off-peak hours and discharge during peak periods, targeting a regulatory scale of ​500,000 kW. Furthermore, ​new energy storage systems​ contribute ​250,000 kW​ of adjustable capacity through rapid charge-discharge capabilities, while standby diesel generators in data centers can release ​150,000 kW​ of potential under non-emergency conditions. Industrial adjustable loads, optimized via production line staggering and equipment operational adjustments, will provide ​500,000 kW​ of flexibility. These dispersed resources across urban areas are integrated through a ​virtual power plant (VPP) platform, achieving "aggregation of fragmented resources." This system not only curbs peak loads but also absorbs surplus electricity during troughs, significantly enhancing the grid's adaptability to supply-demand fluctuations.
