Abstract

The invention provides an anti-collusion micro-grid energy transaction pricing and evaluation system based on a block chain, and the system is constructed based on a block chain network, and an electricity purchaser, a power supplier and an electric power review center are used as nodes of a block chain subsystem for mutual communication connection, thereby forming the block chain subsystem. And on the basis of the Ethereum technology, a consensus mechanism is adopted to enable the nodes to reach a consensus for the transaction, so that micro-grid energy transaction is realized. Wherein the power supply terminal adopts the Bayesian Nash equilibrium game theory to determine the transaction object when calculating the expected income value of the power purchaser, so that the bilateral income can be maximized. The profit expected value is encrypted by adopting the requested comparable encryption strategy, so that the electricity buying party can compare the real expected value even if the real expected value cannot be obtained, and the malicious collusion behavior of the electricity buying party and the power supply party in the bidding and bidding process is effectively prevented; the method has the advantages of decentralization, safety, high efficiency and capability of ensuring purchase-supply bilateral benefit energy transaction.

Description

technical field [0001] The invention belongs to the technical field of energy transaction blockchain, and in particular relates to a microgrid energy transaction pricing and evaluation system based on blockchain for preventing collusion. Background technique [0002] With the continuous increase of new energy types and scale, the number of self-sufficient microgrid energy systems has increased, and the distributed energy trading market with microgrids as the main body has developed rapidly, followed by the microgrid energy trading system. The management difficulty is increased, and the security requirements are higher. Blockchain technology has the characteristics of decentralization, information cannot be tampered with, and it has anonymity, which enables us to operate the energy trading market efficiently and safely. Therefore, blockchain technology has been widely used in the field of microgrid energy transactions, thus bringing many new challenges, among which the prici...
