ICT modeling for integrated simulation of cyber-physical power systems

Abstract

A cyber-physical system is a large and complex infrastructure. Due to the increasing connectivity, the power and cyber systems become more interdependent. Models of the interactions are needed between the power devices and information and communication technology (ICT). A broad range of cyber attacks has become a serious concern. Cyber attacks must be simulated to analyze the consequences on the power grid. Thus, the cyber system must be modeled explicitly and integrated with the power grid model. This paper describes the development and simulation of a novel co-simulation framework that integrates both the cyber and power systems. The objective is to implement the ICT model for real-time interactions with both the power grid and transmission operator. Different industrial grade environments have been developed to simulate the cyber-power interactions. ICT events that may affect the stability of the grid, e.g., cyber attacks, are simulated at the cyber system layer, and their impact analysis is conducted at the power system layer. The proposed co-simulation framework is validated with the IEEE 39-bus system.Index Terms-Cyber-physical system, cyber security, SCADA systems.

IoT-Based Hybrid Renewable Energy System for Smart Campus

“…Many researchers and studies have investigated hybrid renewable energy systems, and from different perspectives, such as energy management systems [13], demand response [14], economic cost [15], carbon dioxide emissions and environmental impact [16], optimizing source size [17,18], communication network [19,20], IoT-enabled smart grid [21][22][23], HRES optimization [24,25], modeling based on international standards [26][27][28][29], optimal location [30], and capacity planning [31]. The author in [13] provided an overview of energy management agent (EMA) framework architectures' ability to manage the energy generation/consumption of DERs/HRES in homes, buildings, and communities.…”

“…This work focuses on the communication level between the local controller of HRES and the microgrid control center, where the status of different renewable energy sources and loads can be collected and communicated to a central controller that determines an appropriate action in the system. Figure 2 shows the IoT-based architecture for HRES which consists of four main layers: the power layer, the data acquisition layer, the communication network layer, and the application layer [20][21][22][23].…”

Smart Grids Co-Simulations: Survey & Research Directions

“…Cybersecurity. Co-simulations have looked into the integration of network failures simulations, data injection attacks in different parts of the SG infrastructure, simulation of cyberattacks, evaluation of intrusion detection algorithms, identification of the vulnerabilities of the integration of the power network and ICT (Stefanov & Liu, 2012;Caire et al, 2013;Chromik et al, 2017;Liu et al, 2018;Ni et al, 2018;Pan et al, 2017;Sadi et al, 2015;Venkataramanan et al, 2016).

Agent-based control of VSC-HVDC transmission grid - A Cyber Physical System perspective

“…A cyber physical system model that could be scheduled and controlled to achieve the desired reference values and minimizing the power consumption of the given system has been proposed in [10]. The work in [11] addresses one of the important issues in CPS which is the information exchange between measurement devices and controller/computational entities and actuators. The integration of Information and Communication Technology (ICT) with power system is more visible now by introducing "Smart Grid" technologies like PMU-based monitoring systems [12].…”

“…Such an integration of cyber elements to the operation and control of the power grid can increase the stability of the system. Modeling the power system as physical system interacting with such cyber devices has been further discussed in [11] and [12].…”
