Embodiment 1

[0046] This embodiment provides a distributed power trading method in a scalable multi-microgrid environment, such as figure 1 As shown, the method includes the following steps:

[0047] S1: Many producers, sellers and consumers in the multi-microgrid are used as the nodes of the blockchain network, and multiple different microgrid operators are trusted nodes in the blockchain to participate in power transactions and act as bookkeepers, thus forming a blockchain network;

[0048] S2: The microgrid operator reviews the user's access to the trading market license, and only users who meet the relevant technical standards are allowed to enter the market for trading, otherwise, they will be restricted from entering the market;

[0049] S3: After entering the market, each user obtains a pair of public-private keys and a wallet address generated by the Elliptic Curve Digital Signature Algorithm (ECDSA), which are used for information encryption and exchange and recording income and ...

Abstract

The invention relates to an extensible distributed power transaction method in a multi-microgrid environment. The method comprises the following steps of S1, constructing a block chain network; S2, examining the permission allowing a user to enter a transaction market; S3, allocating the public and private keys and the wallet addresses; S4, before each transaction gap, enabling a consumer to submit the quotation information, and a producer and a salesman to submit the bidding information; encrypting all quotation information and bidding information by the public and private keys; S5, completing the bidding matching according to a bidirectional auction mechanism; S6, judging whether a transaction rule is met or not, if yes, executing S7, and if not, returning to S4; S7, carrying out power transmission, and enabling an intelligent electric meter to monitor the electric energy transmission of a node in real time; S8, completing the market clearing; and S9, enabling each microgrid operatorto compete for an accounting right according to a workload proof mechanism, and enabling a winner to be an accountant to make a block and embed the block into a block chain network. According to theinvention, the distributed energy transaction system can realize the higher energy transaction efficiency and the stronger stability.

Description

technical field [0001] The present invention relates to the field of power trading systems, and more specifically, to a distributed power trading method in a scalable multi-microgrid environment. Background technique [0002] With the urgent need to actively use clean energy to replace traditional fossil energy, as well as the need for transformation and upgrading of my country's energy structure, the current electric energy market is facing two major problems. First, the development of distributed power sources such as photovoltaics, small fans, and electric vehicles due to subsidies Cost reduction and other issues lead to slow development; second, due to the instability of distributed energy, the power grid cannot make full use of this part of clean energy, resulting in problems such as abandonment of light and wind. With the reform of the electricity sales side in my country, in order to speed up the development of distributed energy and improve the utilization rate of cle...
