This paper presents a real-time cosimulation platform with hardware-in-the-loop (HIL) for performing cyber-physical power system (CPPS) analyses based on RT-LAB and OPNET software. The platform is capable of simulating a power grid and communication network while also reflecting the impact of actual devices and cyber-attacks on the power system. Furthermore, modelling and implementation methods focused on distributed denial of service (DDOS) and man-in-the-middle (MITM) attacks in a communication network are elaborated. A case study of DDOS and MITM attacks in a typical CPPS is demonstrated based on this platform. The simulation results validate the capability of the platform and also show the importance of considering the separate impacts of the communication system, actual devices and cyber-attack in power system simulations.

Highlights

Great developments have occurred in power systems in recent years [1]
In this paper, we have proposed a framework for a cosimulation platform, described the different latencies that affect the system, and discussed the method of modelling the power system, communication system and control device
The cosimulation platform presented in this paper considers the communication system and the actual device and can analyze the impact of latency, data loss and bit errors in the communication system on the power system and evaluates the response delay, rejecting act and fault operations of the actual device

Summary

Introduction

Great developments have occurred in power systems in recent years [1]. In such systems, a large number of sensors, communication equipment and control devices are integrated into the power grid and communication network, which offers the unique opportunity to transform power systems into cyber-physical power systems (CPPSs) [2], [3]. The cosimulation platform in this paper can improve the simulation accuracy of a CPPS compared with that of traditional power simulation methods, and it can be used to study the process of cyber-attacks with HIL, including the start and propagation of consequent faults, thereby providing a reference for the development of security defence measures.
