Shared energy storage overall trading system based on block chain technology and operation method

Abstract

The invention relates to the technical field of energy storage resource operation scheduling and transactions, in particular to a shared energy storage overall trading system based on block chain technology and an operation method. The scheduling node issues an energy storage discharge offer; the energy storage node responds to the charging offer and the discharging offer; the authentication nodereviews the responded energy storage node to form an effective intelligent contract; the monitoring node ensures correct execution of the contract; the settlement node settles the income of the new energy field station and the energy storage resource; and full-automatic and efficient operation of charging-discharging-fee settlement is realized through operation of the system. The method and systemhave the beneficial effects that based on the blockchain technology, effective bidding and automatic execution of the energy storage charging service and automatic and rapid response of the energy storage discharging service are realized through signing and automatic execution of charging and discharging contracts; fair settlement of the energy storage service cost is realized; the energy storageresources of the whole network can fairly participate in the transaction; and the safety of information transmission is ensured.

Description

technical field [0001] The present invention relates to the field of energy storage resource operation scheduling and transaction technology, in particular to a shared energy storage coordinated transaction system based on blockchain technology, and also relates to an operation method of the shared energy storage coordinated transaction system based on blockchain technology. Background technique [0002] In recent years, energy storage technology has developed rapidly, and its application in power systems has become more and more extensive. According to the application grid connection type, it can be divided into the following two categories. One is the self-built energy storage device of the new energy station, which is characterized by close cooperation with the station. Discharge of the power grid, stabilize the output fluctuations of new energy stations, and improve the level of new energy consumption. But because it only serves the local new energy station, the utiliza...

Problems solved by technology

[0004] However, with the continuous increase of energy storage devices in the power system, the centralized dispatching of energy storage resources in the entire network is faced with the situation of increasingly complicated calculation complexity and transaction strategies, and the difficulty of real-time and efficient settlement of transaction fees. The centralized mode of unified control of energy storage resources in the whole network is increasingly unable to meet the needs of shared energy storage for efficiency and fairness, and restricts the sharing of energy storage resources

[0005] The invention patent "A distributed electric energy storage system and operation method based on blockchain" (application number: 201811435889.0) relates to a distributed electric energy storage system and operation method based on blockchain, which can realize distributed energy storage However, it does not involve the coordinated operation of energy storage and new energy stations, that is, it does not involve the bilateral or multilateral bidding process of energy storage and new energy stations, the charging process of energy storage and the settlement strategy of energy storage fees. The problem of low income from existing energy storage, etc.
