Abstract
With the rapid development of the energy internet, the transaction of distributed renewable energy (DRE) is playing an increasingly important role in the energy market. However, in the transaction model of distributed renewable energy combined with public blockchain technology, nodes in the trading network can join or leave the network at any time without any permission, which hinders the regulation of electricity institutions. Corresponding to the transaction principle, a distributed renewable energy transaction authentication mechanism based on consortium blockchain is proposed in this paper. First, certificate authority nodes were set in the transaction network to provide nodes with access authority by controlling the public keys and private keys of trading participants so that they can complete their identity authentication. Next, essential chaincodes in the transaction authentication were designed and deployed on a Hyperledger Fabric blockchain site, and a simulation experiment of a simple DRE transaction was used to elaborate the details on the transaction process. Finally, the proposed model was evaluated according to its performance and proved to be practical and effective.
Highlights
With the world paying close attention to environmental pollution and the energy crisis, it has become an inevitable trend to develop distributed renewable energy (DRE) vigorously, such as solar, wind, and biomass, in order to promote social transformation and sustainable development [1].there is a clear demarcation line between supply and demand for multiple energy types in the scheme of a traditional energy infrastructure, which with its inefficiency in regulating and utilizing distributed energy, could not achieve distributed energy generation at a large scale
In Reference [4], the cluster load of electric vehicles is installed in the energy center of residential quarters where the cogeneration of heat and power and heat pumps are used as energy conversion devices, and it acts as a controllable electric load to promote the operation so that the energy internet is applied in residential quarters
In the transaction authentication model proposed in this paper, participants of transaction authentication can be classified into three types according to user requirements: power unit (PU), generating unit (GU), and matching unit (MU)
