Information security and data interoperation method based on virtual power plant block chain

Abstract

The invention discloses an information security and data interoperation method based on a virtual power plant block chain. The method comprises the following steps: step 1, taking a load aggregator, a power grid and a customer as consensus nodes of an alliance chain; 2, constructing a data layer, a network layer, a consensus layer and a contract layer of the virtual power plant block chain; and step 3, in the demand response process, based on the virtual power plant block chain, performing multi-point backup on an agent electronic contract signed by a load integrator and a customer and a demand response voucher generated by a power grid for the customer by all consensus nodes, and realizing information security protection and data interoperation. According to the method provided by the invention, the demand response voucher which cannot be tampered is formed, the demand response subsidy is ensured to be distributed according to the contract, many characteristics such as decentralization, collective maintainability, intelligent contract, safety and credibility of the block chain are fully utilized, and a new solution is provided for data interoperation and information security problems in the virtual power plant.

Description

technical field [0001] The invention belongs to the technical field of virtual power plant blockchain, and in particular relates to an information security and data interoperability method based on virtual power plant blockchain. Background technique [0002] A virtual power plant is an aggregation of distributed energy resources (DER) with heterogeneous capabilities such as distributed generation (DG), energy storage systems, controllable loads, and electric vehicles through advanced information and communication technology and software systems. and coordination optimization, as a special power plant to participate in the power supply coordination management system of the power market and power grid operation; the core of the concept of virtual power plants can be summarized as "communication" and "aggregation", and the key technologies of virtual power plants mainly include coordinated control technology, smart metering technology and information and communication technology...

AI Technical Summary

Problems solved by technology

[0004] (1) The benefit distribution mechanism in the virtual power plant is not disclosed to the outside world, and a two-way choice of information symmetry cannot be formed between the customer and the load aggregator, which increases the credit cost and high transaction cost in the power transaction process;

[0005] (2) The operation process and results of virtual power plants are opaque to users, and it is difficult to quickly establish the trust of potential users in load aggregators, which increases the difficulty of attracting users and developing incremental markets;

[0006] (3) In the existing system, the virtual power plant uses two-way communication technology to realize the dispatch of information and data in various parts such as the power generation side, the demand side, and the power trading market, but there is a lack of a guarantee system for the information security of the virtual power plant. Unauthorized access to data and risks of malicious tampering;
