Embodiment Construction

[0020] The present invention will be described below in conjunction with the accompanying drawings.

[0021] A distributed power trading method based on blockchain smart contract technology, including:

[0022] Step 1: Establish a DHT network and upload and record the historical power generation information of each electricity seller in the network through smart meters;

[0023] Step 2: The power purchaser sends the power purchase contract to the DHT network for review and then broadcasts the power purchase contract to each node in the blockchain;

[0024] Step 3: The electricity seller who applies to join the power purchase contract sends an application to the DHT network;

[0025] Step 4: The DHT network matches power sellers based on historical power generation information and completes the formulation of power purchase contracts. The newly formed power purchase contracts are verified and confirmed legal by all user nodes and then deployed to the blockchain.

Abstract

The invention belongs to the technical field of intelligent power grids, and particularly relates to a distributed electric energy trading method based on a block chain intelligent contract technology. The method comprises the steps of 1, establishing a DHT network, and uploading historical power generation information of each electricity seller in the network through an intelligent electric meter; 2, sending an electricity purchasing contract to the DHT network by an electricity purchaser, and after auditing is passed, broadcasting the electricity purchasing contract to each node in a block chain; 3, sending an application to the DHT network by the electricity seller applying for joining the electricity purchasing contract; and 4, matching the electricity seller according to the historical power generation information and finishing the making of the electricity purchasing contract by the DHT network, and deploying a newly formed electricity purchasing contract into the block chain after the newly formed electricity purchasing contract is verified and confirmed to be legal by all user nodes. The lightweight calculation based on the block chain is realized, a supply and demand relation is reasonably matched, and the default rate of the intelligent contract is reduced; and the characteristic that the block chain is open and transparent and cannot be tampered realizes economic, efficient, green and de-centralized electric power trading on the premise of ensuring security.

Description

technical field [0001] The invention belongs to the technical field of smart grids, and in particular relates to a distributed power trading method based on block chain smart contract technology. Background technique [0002] Energy is the basis of our production and life. In order to cope with the energy crisis, renewable energy is getting more and more attention. However, due to the decentralized nature of renewable energy, the centralized model of the traditional power grid has disadvantages such as high cost, low efficiency, and data security cannot be guaranteed, making it difficult to meet the requirements of the current situation. The distributed power trading model effectively solves this problem and realizes a low-cost, high-efficiency, environmentally friendly and green power energy network. [0003] Blockchain technology solves the problem of trust between nodes in a decentralized network through a consensus algorithm. Its open, transparent, and non-tamperable fe...
