Blockchain-based Direct-sale Transaction with Peak Shaving and Green Certificate Mechanism

Nowadays, the direct-sale of electricity by large users has become an important development trend. Combining the quota system, it can promote the consumption of renewable energy and achieve the goal of carbon neutrality. In order to make the direct transaction of electricity more transparent and reliable, relying on the blockchain technology with the characteristics of encryption and decentralization, a transaction platform for the direct transaction of electricity has been constructed. The first is that it involves blockchain smart contracts to realize the direct power purchase transaction management function and ensure the safety and trustworthiness of the power direct sale transaction path. Secondly, introduce the load peak shaving market, design peak shaving market transactions and green certificate matching transactions to participate in the direct selling market link, and compare the three transaction modes. Finally, run the constructed model on the designed blockchain trading platform to complete the entire process of energy trading. The results show that the participation of the green certificate mechanism and the peak shaving mechanism in the direct purchase market can rationally allocate market resources and guide emission reduction through market means, which is conducive to the further realization of carbon neutrality in electricity market transactions.
