Abstract

The invention discloses a power distribution network distributed energy transaction method and system based on a block chain. The transaction method comprises the following steps: establishing a blockchain network, obtaining quoted prices of an electricity purchasing party and an electricity selling party, adjusting the quoted prices of the electricity purchasing party and the electricity sellingparty through a model considering network loss and voltage constraints, clearing an adjusted declaration result, and uploading the clearing result to a block chain. The transaction system comprises ablock chain transaction node, a block chain network, a distributed processing subsystem, a centralized processing subsystem A and a centralized processing subsystem B. According to the invention, thetransaction problem of distributed energy in the presence of power grid constraints is solved, and by adjusting the quoted prices of both electricity purchasing and selling parties, transactions having little influence on the power grid can be transacted firstly on the premise of reducing the benefit loss of both electricity purchasing and selling parties, thereby ensuring the safe operation of the power grid and providing an optimal quotation decision by the supply object of the target resource so as to maximize the market revenue of the supply object.

Description

technical field [0001] The invention belongs to the technical field of distribution network electric power, and in particular relates to a blockchain-based distributed energy trading method and system for a distribution network. Background technique [0002] With the promotion of Distributed Renewable Energy (DRE) and Demand Response (DR) technologies, the boundaries between generators and users in the distribution network are gradually blurring. The sheer number of these generators makes scheduling more difficult. DRE power generation resources have the characteristics of small capacity, large quantity, and wide distribution, which means that the centralized dispatching method faces problems such as high operating costs and long time consumption. Therefore, scholars at home and abroad have proposed a distributed scheduling method with better scalability and reliability, which is more suitable for optimal scheduling of distributed resources. [0003] In the design of the d...
