Transaction Mechanism Of Energy Storage User In Blockchain-Based Ancillary Service Market

The establishment of ancillary service market greatly increases the stability and flexibility of the power grid.In recent years,the promotion of the market has been the popular direction in China.As a result,the demand of ancillary services is increased,and more users participate in the ancillary service market,which puts forward higher demand to the power grid.In this thesis,the structure of blockchain ancillary service market is built,and the parameter demand of the market for services is analyzed.The parameter competition process of users on the market supply side is realized.The transaction mechanism of increasing the response rate of energy storage to capacity demand is further developed.Firstly,the latest definition of ancillary services in China is analyzed and the classification method of ancillary services based on market demand for user parameters is established.Besides,the particularity demand of ancillary service market for user response is considered and the enlightenment of existing market trading mechanism for subsequent market improvement is summarized.The market structure of blockchain ancillary services is further depicted.Secondly,according to the existing ancillary service market demand for competition between the user,the unification of the user in the market and the node in blockchain is realized by the proof of capacity（POC）consensus mechanism.A competition mechanism based on the consensus process is developed,which achieves the competition among the user parameters based on the blockchain.The simulation proves the validity of the mechanism.Finally,on the basis of the unification of the users and nodes,a supply-demand split transaction mechanism is designed for the participation of energy storage in the ancillary service market by filling and erasing process of users’ hard disks in the capacity competition.The simulation results show that the market call more units to respond the demand for capacity The response rate of demand has improved compared to day-ahead prediction,long-terms contract and traditional blockchain trading markets.
