Blockchain-based electricity charge settlement method and system for energy storage station

Disclosed is a blockchain-based electricity charge settlement method and system for an energy storage station. A trusted terminal directly collects two-way electricity quantity data of an energy storage station, and distributes the two-way electricity quantity data to a blockchain; and a consensus node of a power-consuming enterprise and a consensus node of an energy storage station investment operator in the blockchain perform consensus calculation on the two-way electricity quantity data, and write the two-way electricity quantity data into the blockchain after reaching a consensus. The two-way electricity quantity data is accurate and cannot be tampered with, ensuring authenticity of the two-way electricity quantity data. A smart settlement contract is executed, an electricity charge settlement result is generated automatically based on the authentic and credible two-way electricity quantity data to ensure authenticity of the electricity charge settlement result, and the electricity charge settlement result is written into the blockchain to prevent the electricity charge settlement result from being tampered with. S1l A trusted terminal collects two-way electricity quantity data ofan energy storage station, and distributes the two-way electricity quantity data to a blockchain A consensus node of a power-consuming enterprise and a consensus node of an energy storage station investment operator in the blockchain S12 perform consensus calculation the two-way electricity quantity data and after reaching a consensus, select one of the consensus node of the power-consuming enterprise and the consensus node of the energy storage station investment operator as a first accounting node The first accounting node processes the two-way electricity quantity data to obtain a first target block, and writes the first target block into the blockchain Execute a smart settlement contract, obtain basic settlement data from S4 the blockchain, perform electricity charge settlement based on the basic settlement data to obtain an electricity charge settlement result, and distribute the electricity charge settlement result to the blockchain, where the basic settlement data at least includes: two-way electricity quantity data in the first target block After reaching a consensus on the electricity charge settlement result, S15 the consensus node of the power-consuming enterprise and the consensus node of the energy storage station investment operator in the blockchain select one o
