Wind-solar storage data remote security transmission method and system

Abstract

The invention discloses a wind-solar storage data remote security transmission method and system, and the method comprises the steps: enabling an on-site module to obtain the information of a wind-solar storage system, forming a wind-solar storage self-description information model, judging whether a data transmission channel between the on-site module and a main station is normal or not, in response to the normal data transmission channel, carrying out remote master station authentication, in response to successful authentication of the remote master station, by the in-situ module, encryptingthe content of the request message by adopting a key Encoding AESKey based on an AES algorithm to obtain a ciphertext, assembling the ciphertext, an on-site encrypted signature, a time scale parameter and a device ID parameter into a request message, sending the request message to the remote master station, by the remote master station, receiving the request message, calculating to obtain a master station encrypted signature by adopting a secure Hash algorithm according to the time scale parameter, the device ID parameter and the master station password parameter, comparing the on-site encrypted signature with the encrypted signature of the master station, and in response to successful authentication of the on-site module, by the remote master station, decrypting the ciphertext by adopting the key Encoding AESKey based on an AES algorithm to obtain data content.

Description

technical field [0001] The invention belongs to the technical field of new energy power generation, and in particular relates to a method and system for remote and secure transmission of wind-solar-storage data. Background technique [0002] Due to the characteristics of meteorological resources, the output of wind power and photovoltaics is intermittent and random, and often does not match the load characteristics. In large-scale applications, they are restricted by various aspects. In recent years, with the gradual development of energy storage technology, its cost and price have also been decreasing, and the conditions for large-scale use have initially been met. The combined use of wind power, photovoltaics and energy storage devices forms complementary advantages and realizes the smooth output of new energy. Therefore, the combined power generation of wind, wind and storage is currently more and more widely used. There are already many use cases for the power grid syst...

AI Technical Summary

Problems solved by technology

Many power generation groups or third-party operation and maintenance organizations have established large-scale remote centralized control centers in order to realize the unmanned or at least few people on duty of wind, solar and storage power stations; however, in the process of data transmission, they often face the following problems: the data model is uncertain, processing High complexity; lack of effective identity authentication and encryption mechanism, data security needs to be strengthened; in the process of data transmission, lack of a unified transmission control mechanism to ensure data synchronization

The current communication method mainly adopts the traditional power communication protocol, which is easily affected by the unstable connection of the public network. At the same time, it also has disadvantages such as large traffic consumption, heavy load on the server side, and complex design.

In addition, there are problems such as bare data transmission and no security protection measures, which may easily cause data leakage

Therefore, the current wind-solar-storage system has problems such as complex data transmission, inconsistent models, no security mechanism, and low integrity of the transmission protocol, which affects the quality of remote transmission of wind-solar-storage data.
