Abstract

Data communication security between power systems, which has become a chronic problem in the classical network, is characterized by the application of information communication technology (ICT) in modern network models. Nowadays, the electricity network is spread over very large areas, and the load taking, and load shedding instructions are transmitted one-way and unsafe in the current structure. However, utilities in the smart grid are developing new methodologies to secure the communication infrastructure. This article presents a design that will make the current grid model more reliable and provide a secure data communication in accordance with the modern grid infrastructure. This design provides auxiliary communication codes such as chaotic codes embedded in the communication instructions between power systems, which are generation balance instructions sent to the power plants by the load dispatch center to achieve frequency balance. Used as a case study, one-day instructions are transmitted and encoded four times a day, which is the amount of capacity that only the receiver and transmitter can understand with two-sided encryption. The necessary reserve capacity, chaotic encryption and suitability for real-time applications were evaluated using experimentally obtained power system data for frequency control, which is very important in terms of sustainability in energy and economy against cyber-attacks, and very accurate results were obtained.

Highlights

The purpose of power system operation is to be able to effectively carry out load changes within the scope of legal obligation without disturbing the system stability, for which a correctly determined and reliable reserve control should be provided [1]
All units included in the interconnected system are transmitted in coordination with the center with a special coding and a high-security communication technology is provided. This technology is at a high level of security, which is an indispensable imperative to protect classic and smart networks from cyber-attacks
The instructions coded with chaotic encryption; the reserve balance capacity quantities given by the operator to keep the frequency constant become mandatory to transmit units
