【Abstract】Renewable energy generation is greatly affected by the weather, and electricity is not easily stored in large quantities. So, the call auction trading based on the rule of the maximum trading volume is of great significance to promote the electricity consumption of microgrids. Therefore, in microgrid electricity call auction trading, aiming at the problems, such as bidding messages may leak users' privacy, they may also be eavesdropped or tampered with in the bidding process, and the balance between privacy protection and supervision cannot be achieved, a privacy protection scheme for bidding users of peer-to-peer electricity call auction trading in microgrids is proposed. It consists of a market layer and a blockchain layer. Based on the improved certificateless ring signcryption and timed-release encryption algorithms, the market layer is used to hide the user's real identity while encrypting the bidding message and track illegal users. The blockchain layer is used for trading settlement and trading record storage to ensure data storage security. The security is proved theoretically. Performance analysis and simulation results indicate that computational and communication costs are low. Especially the verification cost is low and increases slowly with the increase in the number of ring members.
