摘　　要：为实现微电网内部分布式电源（distributed generation,DG）与用户电量直接交易,该文提出基于区块链和连续双向拍卖机制的微电网电力交易模式及报价策略。买卖双方首先通过连续双向拍卖机制完成交易匹配,考虑到连续拍卖市场中价格波动频繁,提出自适应进取性交易策略,使得交易方能够根据市场变化及时调整报价;然后DG和用户通过区块链系统实现交易电能数字证明和费用的交换,并且通过多重签名机制保证DG违约时用户的利益;在电能资产数字证明中,通过对交易脚本中的序列号添加特定标记来代替交易电量,并且根据交易电量不同动态调整数字证明大小。最后,该文通过具体微电网案例验证交易机制的可行性,并给出微电网交易结算流程。In order to realize power directly transaction between distributed generations（DG） and loads in microgrid, this paper proposed an electricity transaction mode and strategy in microgrid based on blockchain and continuous double auction（CDA）. Firstly, the buyer and seller shall first complete the transaction matching through CDA. Considering the frequent price fluctuation in CDA market, this paper proposed an adaptive aggressiveness strategy, which enabled the trader to adjust the quotation timely according to the market changes. Then DGs and consumers exchanged trading power digital certificate and expenditure on the blockchain system, and the consumers＇ interests were guaranteed by multi-signature if DG defaults. Digital certification of electricity energy assets was replaced by the sequence number with specific tags in the transaction script, and the size of digital certification could be adjusted according to transaction energy quantity. Finally, the feasibility of market mechanism through specific microgrid case and settlement process was also given.
