摘要

相对于传统电力市场，微电网准入门槛低、用户个体趋利性强、分布式电能设备产能不稳定等问题可能使得微电网交易陷入信任危机。为此，文中提出了适用于微电网电能交易区块链的信用共识机制。首先，分析常用的共识机制及其在微电网应用场景中的缺陷。同时，设计了微电网电能交易区块链账户节点属性，改进了基于区块链的微电网电能交易流程。然后，建立微电网节点信用值评定机制，完成了节点信用值的公开、公平评定。最后，提出了基于信用证明的共识机制（PoCS），实现信用值影响共识过程，经济因素激励用户节点维护信用值。仿真结果证明，所提出的适用于微电网电能交易区块链的信用共识机制及微电网电能交易的智能合约能够以经济收益激励信用高的节点，抑制微电网内的节点失信现象。

Abstract

Compared with the traditional electricity market

the low barriers to entry of microgrid

strong profit-seeking tendency of individual users and unstable production capacity of distributed power equipment may make the microgrid transactions fall into a crisis of trust. Therefore

a credit consensus mechanism suitable for the microgrid energy trading blockchain is proposed. First

common consensus mechanisms and their defects in microgrid application scenarios are analyzed. Meanwhile

the node attributes of the microgrid energy trading blockchain account are designed

and the microgrid energy trading process based on the blockchain is improved. Then

the credit value evaluation mechanism is established for the microgrid node

and the open and fair evaluation of node credit value is completed. Finally

the consensus mechanism based on proof of credit and stake (PoCS) is proposed

which implements that the credit value affects the consensus process and economy factor encourages user nodes to maintain their credit values. The simulation results show that the proposed credit consensus mechanism suitable for microgrid energy trading blockchain and the smart contract for microgrid energy trading can stimulate high-credit nodes with economic benefits and restrain the dishonesty phenomenon of nodes in microgrid.
