The invention discloses a secure communication method for a virtual power plant based on quantum key fusion, including: identity authentication: based on communication requirements, identity authentication is performed between a client and a server in a virtual power plant and a root key is obtained; Key distribution: based on the obtained root key, correspondingly generate key encryption key and message authentication key, and then realize data encryption key negotiation to obtain data encryption key; data encryption: use data encryption key to encrypt data to be encrypted Encryption processing and corresponding data communication; in the above process of identity authentication or key distribution, the quantum key server is used to realize quantum key agreement, and the negotiated quantum key is used for corresponding identity authentication or as a data encryption key . The present application can provide a safe, reliable and cost-effective secure communication method through key fusion, and improve the communication security and reliability of the virtual power plant.
Description
technical field [0001] The invention relates to the technical field related to power system communication, in particular to a method for secure communication of a virtual power plant based on quantum key fusion. Background technique [0002] At present, with the grid-connected power generation of a large number of different types of new energy and distributed power generation equipment, new severe challenges have been brought to grid dispatching and safe operation. Virtual power plant is an effective form of rational integration and optimal utilization of distributed new energy, and it can also effectively participate in the energy transaction process of the electricity market. However, the current research on virtual power plants mainly discusses issues from the perspective of economical and reliable operation of the power system. The specific work mainly includes energy management, system operation, optimal scheduling, and predictive modeling. Communication and other tech...
