Power distribution network electric energy distributed transaction model based on distributed database support

Abstract

The invention discloses a power distribution network electric energy distributed transaction model based on distributed database support, which is characterized in that electricity purchasing and selling parties send electricity purchasing and selling information through a distributed database network, and an electric energy transaction negotiation market chain code model completes negotiation oftransaction electric quantity and transaction price to form a temporary contract; the network security constraint chain code model performs security check on the temporary contract line power flow andthe node voltage; and the on-chain and off-chain model determines the temporary contract passing the security check as a final contract, and executes a transaction. According to the invention, the market main body is allowed to participate in the power market in a decentralized manner and negotiate the transaction electric quantity and the transaction price, the electricity purchasing cost of themarket main body can be effectively reduced, and the electricity selling income of the market main body is increased. Line power flow blocking and node voltage deviation conditions can be effectivelyjudged, and safe operation of a power distribution network is facilitated. The constructed distributed database capacity expansion architecture can ensure the safety and traceability of all historical data storage while ensuring the computing power of the distributed database.

Description

technical field [0001] The invention belongs to the technical field of distribution network electric energy trading, and in particular relates to a distribution network electric energy distributed transaction model supported by a distributed database. Background technique [0002] With the deepening reform of my country's energy market, further promoting energy distributed trading, establishing a free competition, open and transparent market, more and more market players participating in the energy trading market have brought the following problems to the traditional centralized trading model: 1) The transaction center needs to maintain and manage the transaction data and transaction process, which increases the operating cost; 2) There is a trust problem between the transaction center and the trader; 3) The centralized database increases the risk of transaction data being tampered with, directly threatening the transaction data safety and the interests of the transaction part...

[0002] With the deepening reform of my country's energy market, further promoting energy distributed trading, establishing a free competition, open and transparent market, more and more market players participating in the energy trading market have brought the following problems to the traditional centralized trading model: 1) The transaction center needs to maintain and manage the transaction data and transaction process, which increases the operating cost; 2) There is a trust problem between the transaction center and the trader; 3) The centralized database increases the risk of transaction data being tampered with, directly threatening the transaction data security and the interests of the transaction parties

[0004] As the scale of distributed transactions increases, the number of market entities participating in transactions increases, especially when considering complex network physical constraints, the limited computing power and response speed of distributed databases will reduce transaction throughput and limit transaction speed

Some existing studies combine the distributed transactions on the distributed database chain with the centralized scheduling off-chain through the Lightning Network, which increases the computing power of the distributed database to a certain extent, but the off-chain transaction process is not stored in the distributed database. , which affects the security and traceability of information to a certain extent
