    Abstract:

    Charging network is one of the typical scenarios of Energy Internet. The in-depth study of charging network operation mode and key technologies can effectively alleviate the impact of electric vehicle charging load on the power system. Meanwhile, the research can also provide support for promoting large-scale renewable energy consumption. Considering the policy background of renewable energy quota system, the definition and operation framework of charging load aggregator is proposed. On this basis, the driving force of charging load aggregators to participate in the green certificate trading market is analyzed, and then the two-level green certificate trading mode inside and outside the charging load aggregators is constructed. Then, in view of the coupling mechanism of green certificate trading, carbon emission trading and electricity market trading, a multi-market coordination mechanism is established. Finally, according to the green certificate trading mode, through the four dimensions of perception layer, network layer, platform layer and application layer, the concept of green certificate trading system and key technologies for charging load aggregator are put forward. The research results will support the development and construction of charging load aggregating system. This study can also provide a reference for the design and development path construction of Energy Internet business model in China.
