Microgrid electric energy transaction method based on master-slave intelligent contract

Abstract

The invention discloses a microgrid electric energy transaction method based on a master-slave intelligent contract, and the method comprises the steps: firstly, building a microgrid information physical system, carrying out the real-time monitoring and collection of system data, building a real-time electricity price model of an electric power transaction system stage, and marking transaction reference electricity prices in the master-slave intelligent contract; secondly, creating transactions among the intelligent nodes of the microgrid users according to actual supply and demand conditions,and signing intelligent contracts; and finally, enabling the transaction to achieve the consensus, enabling a blockchain cloud platform to automatically execute the smart contract, and writes the process data generated by the transaction into the block for storage to complete the transaction. The microgrid physical topology and the transaction cloud platform are efficiently interconnected. Real-time monitoring and cloud computing of each electric quantity of a microgrid user side are realized. By combining a physical infrastructure, an internet communication technology, a cloud computing technology and a block chain bottom layer technology, the electric power market electric power resource and price trend are intelligently analyzed, deployment and execution of an intelligent contract arecompleted and accurate and efficient execution of microgrid electric power market transactions is ensured.

Description

technical field [0001] The invention relates to a microgrid power trading method based on a master-slave smart contract. Background technique [0002] At present, the depletion of fossil energy and the increasingly prominent problems of environmental pollution, the demand for electricity of users increases rapidly with the economic development, and the distributed generation (DG) network using renewable clean energy is used as a power trading scheme for the supply and sale of electricity much attention. As a form of "grid within a grid", the microgrid solves the problem of DG grid connection, reduces the difficulty of DG operation and maintenance, and develops its advantages such as clean and environmentally friendly, flexible and changeable methods, and strong reliability. In view of the characteristics of using renewable energy such as wind energy or solar energy to generate electricity that is overly dependent on changes in the external environment, has strong intermitte...

Problems solved by technology

However, due to the short-term and uncertain nature of micro-grid transactions compared with large-grid power transactions, the participants in power transactions are prone to form data islands, requiring third-party operators to spend a lot of manpower and material resources to frequently proofread transaction data, and the efficiency of transaction conclusion is low. The market operation and management mechanism is not yet mature
