Abstract：[Objective]Based on the dual-carbon background, a coupled demonstration system of "Photovoltaic-Storage-Charging-Heat" has been constructed in the Sino-German(Changzhou) Innovation Industrial Park, in order to demonstrate the dynamic performance of the coupled demonstration system, and to explore the practical effect of the multifunctional complementary energy system in intelligent energy management. [Methods] Based on the coupled demonstration system, this paper introduces the system energy conversion paths(photovoltaic(PV) power generation, thermal energy storage, V2G charging, and peak peaking in the valley), and analyses the dynamic trends of parameters such as PV power generation, storage charging/discharging, thermal load efficiency, and the proportion of renewable energy sources, etc., by using the actual operation data. [Results] PV power is positively correlated with solar radiation intensity,maximum power 343 kW, but significantly affected by meteorological conditions,power drops to 70 kW during rain and snow; the peak charging power of the energy storage subsystem is 107.6 kW, realising intelligent control of charging and discharging; the fast charging power of V2G charging pile reaches 77.8 kW, and the power fed back to the power grid is 5.1 kW. The power of heating supply is correlated with the ambient temperature There exists a 2 h time shift, the highest total energy consumption of the system is 661 kW, and the peak share of renewable energy is 33.9%. [Conclusion] Through multi-energy coupling and intelligent scheduling, the system achieves the goals of efficient energy use and annual carbon reduction of 1 000 t,providing a feasible path for the zero-carbonisation of industrial parks.
