Abstract

The invention relates to a distributed electric energy transaction system and method in a microgrid, the system comprises a plurality of user energy manager nodes and a regional energy manager node, the nodes are in information communication to form a block chain network, and the user energy manager node is connected with a local user's intelligent electric meter through a power line. The user energy manager uploads the electric information and the transaction plan to a block chain network through a block chain data module, and inquires transaction information through the block chain data module; The regional energy manager collects user electric information and a transaction plan, and matches transaction objects for users based on continuous bilateral auction; The intelligent electric meter obtains the charging and discharging requirements by checking the block information and executes charging and discharging; And finally, fund settlement is completed through an intelligent contract.In the operation process of the system, the user energy manager, the regional energy manager and the intelligent electric meter perform self-decision making and automatic operation, distributed renewable energy sources in the microgrid can be fully utilized, optimal allocation of resources is achieved, and meanwhile the benefits of all participants are guaranteed.

Description

1. Technical field [0001] The invention belongs to the technical field of electric energy trading in the energy Internet, and in particular relates to a distributed electric energy trading system and method in a microgrid. 2. Background technology [0002] Energy shortage and environmental pollution are worldwide problems, and making full use of distributed renewable energy is an effective way to solve these two problems. However, due to the intermittent and fluctuating characteristics of distributed energy resources, it is difficult for them to directly participate in the electricity trading market in large power grids. Therefore, it is necessary to establish a distributed electric energy trading market locally to reduce the adverse impact of distributed electric energy on the large power grid, and at the same time improve the utilization rate of renewable energy. [0003] The traditional distributed electric energy adopts the method that users are self-sufficient, and the...
