Abstract:

In order to solve the problem of distributed multi-energy grid connection， distribution and scheduling coordination， considering that the interaction of distributed energy is dynamic and real-time， and the supply and demand sides have data privacy and security requirements， a distributed energy heterogeneous is constructed. Blockchain network model. In this model， a consortium chain mechanism of cross-chain information collaboration and multi-organization complementary transactions is designed to reduce the traditional blockchain consensus confirmation and transaction delay. Combined with the need to improve energy utilization efficiency， control indicators such as low-carbon factor， decay service quality and comprehensive energy utilization rate are introduced to build a reputation value bidding strategy based on electricity sellers， and the automatic transaction and evaluation functions are embedded in the smart contract of the model. Provide support for the settlement of this bidding strategy. Through the multi-scenario setting， the energy blockchain bidding model with the participation of virtual power plants is compared and analyzed. The calculation example shows that the model： on the basis of ensuring the interests of energy transaction participants and data security， the market transaction mechanism is more flexible and promotes Local consumption of clean energy contributes to low-carbon sustainable development. At the same time， the bidding strategy can provide a theoretical reference for exploring the optimal control strategy for participants in the future energy utilization system.
