Local area multi-microgrid power transaction pairing method based on blockchain technology

Abstract

The invention discloses a blockchain technology-based local multi-microgrid power transaction pairing method, and a multi-microgrid is an important component of an energy internet as a novel distributed power generation system. Selection of power generation resources and electric energy transaction have a series of problems of obvious centralization, low fairness and reliability and the like. Aiming at the defects of the micro-grids in real-time power transaction, the invention provides a multi-micro-grid power transaction pairing method based on a blockchain technology, constructs a competitive power spot market of decentralization of a transaction part and multi-seller-multi-buyer, and realizes integration of source-sale. Through the processes of transaction information uploading, matching and encryption and intelligent contract automatic settlement, the ant colony algorithm is utilized to realize random quotation and random pairing of each subject, and multi-target optimization is realized. Unification of power transaction energy flow, information flow and currency flow is realized in the whole process, and reasonable distribution of electric energy resources and openness and transparency of power transaction are ensured.

Description

Technical field: [0001] The present invention relates to a local multi-microgrid power transaction matching method, in particular to a local multi-microgrid power transaction matching method based on block chain technology. Background technique: [0002] At present, the acceleration of primary energy consumption, serious environmental degradation and low utilization rate of new energy are important challenges facing the global energy economy. The emergence of the Energy Internet provides the possibility for the access and large-scale use of various energy information. The local multi-microgrid system composed of multiple microgrids is considered to be a typical subnetwork of the Energy Internet, and it is also an important prerequisite and necessary way to realize the development of Energy Internet technology. With the rise of microgrid technology, it is particularly important to study microgrid power trading scenarios. However, there are a series of problems in the select...

Problems solved by technology

[0004] Fog computing and haze computing combined with distributed networks can reduce the pressure on the central server to a certain extent; MEC mobile edge computing can also maximize the sinking of computing power. However, the above methods can only be used for users directly facing edge nodes. For efficient processing, if you want to interact across regions, you need to go through the central server or strengthen the computing and communication capabilities of edge nodes

However, to improve the above architecture, the cost is too high, and at the same time, it needs to go through the central server, so it is impossible to achieve complete decentralization
