Improved PBFT Consensus Mechanism for Multi-virtual Power Plant Transactions
摘要
Abstract
The diversity of distributed energy investment entities makes it more difficult to build trust in the process of interaction between resources,so it is necessary to explore the interaction mode of multi-virtual power plants and build a corresponding trust system.Based on the main and side blockchain technology,this paper constructs an overall architecture for the multi-virtual power plant transaction model and clarifies the transaction process of multi-virtual power plant.A cross-chain channel is constructed through the main side anchoring technology to realize the on-chain collaborative operation mode of multi-virtual power plants.To solve the problems of the lack of trust environment and the decline of blockchain performance caused by the low enthusiasm of nodes to maintain the blockchain network environment,a differentiated credit evaluation index is proposed to standardize node behavior based on different node functions,and the practical byzantine fault tolerance(PBFT)algorithm is improved using this index.Experimental results show that the consensus algorithm improved by the differentiated credit evaluation indicators can build a trust environment and improve the consensus efficiency under the proposed multi-virtual power plant architecture.关键词
