摘要
With the increasing penetration of distributed energy resources (DERs), it is a new trend that DERs can transact with neighboring consumers. Compared with a traditional electricity transaction, the default problem in DER transactions is more serious due to the uncertainty of DER outputs and owners' desire of profits. This paper presented a credit management method for DER transactions by using blockchain technology. Firstly, the sources and damages of the credit risk in DER transactions were analyzed and a credit evaluation index in DER transaction was introduced. Then, a DER transaction model based on blockchain was presented. In the credit risk management process, a credit assessment technology for DER transaction based on blockchain was proposed that can assess the credit of DERs in a transparent and just manner. A credit risk control mechanism based on PoC (proof-of-credit) consensus algorithm was proposed. The algorithm encourages participants to maintain their credit scores in an incentive compatible way and avoids the credit problem in the DER transaction. Simulation results show that, with the proposed DER transaction smart contract and the credit risk control mechanism, participants with higher credit scores gain more profits than those with lower credit scores. © 2019 Chin.
