Embodiment Construction

[0054] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0055]Blockchain is essentially the integration and innovation of distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm and other computer technologies. To put it simply, blockchain is a technical solution in which any number of nodes collectively maintain a reliable database in a decentralized and trustless manner through cryptography. The data structure of the blockchain is mainly divided into two parts: 1) the block header, which mainly contains the hash value of the previous block, which is used to connect the previous block to ensure the integrity of the blockchain; 2) the block header The block body contains the main information of this block (such as transaction information), which together with the hash value of the previous block and the random number constitute the hash value of thi...

Abstract

The invention provides an energy block chain network and an operation and scheduling method of a virtual power plant based on the network. According to an energy block network EBN, all generating units G form a power supply index block chain CPSIB according to mapping alpha. A power transaction set T is formed by the transaction process of all generating units G and power units P, a power transaction block chain CETB is formed according to mapping beta, and in the process of forming T, all generating units G and power units P complete a transaction according to a concrete contract. According to the energy block chain network and the operation and scheduling method, an energy block chain network model is introduced into the operation and dispatching process of the virtual power plant, while the overall efficiency of the virtual power plant is improved, the virtual power plant obtains an information security guarantee of a higher degree by the cryptographic characteristics of the block chain.

Description

technical field [0001] The invention belongs to the field of control theory and control engineering, and specifically relates to information operation and scheduling of a virtual power plant. Background technique [0002] With the rapid development of distributed renewable energy, demand side management and virtual power plant (virtual power plant, VPP) have become the key factors for moving from smart grid to energy Internet [1], among which virtual power plant is the most important technology. Virtual power plant technology refers to the organic combination of controllable loads, distributed electric resources (DER) and energy storage systems through a virtual control center, allowing them to participate in the operation as special power plants in the grid. [0003] However, there are some common problems in the current virtual power plant operation process: (1) The virtual power plant needs to aggregate distributed energy sources in different regions, so it needs to deal ...
