Original article | New energy power AC | April 1, 2025 16:37 ---------------------------------------------------- [Why is this combination essential?] ■ Resource aggregation: Efficient management of distributed energy ▼ Background and significance As the proportion of new energy in the power system exceeds 40%, real-time control of distributed resources (such as EVs and storage batteries) is essential to adjust the unstable output of solar and wind power generation. However, traditional centralized management methods cannot integrate resources with different owners and technical specifications. ▼ Case study: Ningde era "Energy Cloud" ・Implementation details: Connecting 1.2 million EVs (total capacity 6GWh) to the power grid ・Technology innovation: Charge and discharge control using V2G3.0 protocol (designed to reduce battery burden) ・Results report: Achieved instantaneous power adjustment of 500MW in Zhejiang Province, generating annual revenue of 2,300 RMB for users ■ Spatio-temporal optimization: Resolving supply and demand mismatches ▼ Specific issues Inconsistencies between regions and time periods are becoming more serious, such as the overlap between the peak solar power generation period in the northwest and the valley of power demand in the eastern industrial area. ▼ Successful model: Tesla South Australia VPP ・Expansion scale: Building a home battery network for 12,000 households ・AI utilization: Weather forecast-linked Autobidder automatically adjusts supply and demand ・Economic effect: 40% reduction in household electricity costs, 4.8 years shorter payback period for equipment investment 【Points of evolution in 2025】 ◎ At the forefront of technological innovation 1. Ultra-high speed control: command transmission in less than 50 milliseconds (Huawei HarmonyOS adopted) 2. Precision prediction: 99.3% accuracy achieved with 3D digital twin (Ali Cloud performance) ◎ New revenue model | Revenue type | Specific examples | Performance values | |--------------------|--------------------------|---------------------| | Peak adjustment | Ningde Times Zhejiang Province project | 0.8 RMB/kWh | | International electricity arbitrage | EU cross-border trading | 0.18-0.25 EUR/kWh | | Environmental value sales | Tesla South Australia | +0.05 AUD/kWh | 【Challenges for the Future】 ① Data governance Referring to the EU's "Guidelines for Energy Information Protection," clarify the rights of user data ② Unification of technical standards Establish interconnection standards for charging equipment and storage batteries (based on China Electricity Federation 5 standards) ③ Strengthening risk management Develop financial derivatives to respond to fluctuations in electricity prices (referring to the Guangdong pilot case) ---------------------------------------------------- In conclusion: The collaboration between electricity retailers and virtual power plants is a "redesign of the energy ecosystem" that goes beyond mere technological integration.
