“…The sources of cyber threats can be generalized as two aspects: random communication failures and malicious attacks. The random communication failures of the microgrids could occur due to the vulnerability of the sophisticated communication scheme, while mission critical applications require accurate and real-time operations [52]. Delayed or unsuccessful communication attempts possibly lead to ineffective or inefficient response to emergency and alarm events, which may further trigger the response of the microgrid protection scheme, and cause severe cascading failures.…”

Similar to utility grid and other terrestrial microgrids, aircraft electric power systems (EPS) and shipboard microgrids have their own power generation, distribution, utilization and generation storage. The rapid development of power electronics technology has allowed the converters to operate at DC voltage levels required for transmission, distribution and consumption. However, the coordination among power electronic converters can lead to malicious intrusions that aim to manipulate microgrids' operation and cause deviation from their mission-critical objectives. Such manipulations may lead to disturbances during motion, thus posing serious risks to passenger lives and cargo. The disturbances can also affect operations in critical sectors like commercial transportation and defence which may directly influence the global economy and national security. This chapter overviews the industrial security measures considered for microgrids in mission-critical applications, such as those found in electric aircrafts and shipboard power systems, with further insights on vulnerable areas which can be exploited by stealthy attackers.

“…In this case study, a distributed power and energy management system is deployed in a 4-zone MVDC ship power system (Fig. 23) [112]. The physical system, i.e., the electrical and mechanical properties of the SPS, are modeled and simulated on a RT Simulator (RTS) while sensor data coming from the devices modeled inside the RTS are sent, through fiber optic and an FPGA, to the communication infrastructure connected to the respective external controllers.…”

In this paper, a broad overview of the current research trends in power-electronic innovations in cyberphysical systems (CPSs) is presented. The recent advances in semiconductor device technologies, control architectures, and communication methodologies have enabled researchers to develop integrated smart CPSs that can cater to the emerging requirements of smart grids, renewable energy, electric vehicles, trains, ships, internet of things (IoTs), etc. The topics presented in this paper include novel power-distribution architectures, protection techniques considering large renewable integration in smart grids, wireless charging in electric vehicles, simultaneous power and information transmission, multi-hop network-based coordination, power technologies for renewable energy and smart transformer, CPS reliability, transactive smart railway grid, and real-time simulation of shipboard power systems. It is anticipated that the research trends presented in this paper will provide a timely and useful overview to the power-electronics researchers with broad applications in CPSs.

“…Both subsystems have support for multiple industrial protocols utilized for the communications between the physical or simulated EPS assets. Advanced control schemes and experimentation with communication network components are also supported via HIL simulations [31], [73]. Additionally, the impact of unexpected failures or cyber-attacks targeted at these components can be examined in a controlled environment where minimum risk exists [32].…”

Cyber-physical systems (CPS) are interconnected architectures that employ analog, digital, and communication resources for their interaction with the physical environment. CPS are the backbone of enterprise, industrial, and critical infrastructure. Thus, their vital importance, makes them prominent targets for malicious attacks aiming to disrupt their operations. Attacks targeting cyber-physical energy systems (CPES), given their mission-critical nature, can have disastrous consequences. The security of CPES can be enhanced leveraging testbed capabilities to replicate power systems operation, discover vulnerabilities, develop security countermeasures, and evaluate grid operation under fault-induced or maliciously constructed scenarios. In this paper, we provide a comprehensive overview of the CPS security landscape with emphasis on CPES. Specifically, we demonstrate a threat modeling methodology to accurately represent the CPS elements, their interdependencies, as well as the possible attack entry points and system vulnerabilities. Leveraging the threat model formulation, we present a CPS framework designed to delineate the hardware, software, and modeling resources required to simulate the CPS and construct high-fidelity models which can be used to evaluate the system's performance under adverse scenarios. The system performance is assessed using scenario-specific metrics, while risk assessment enables the system vulnerability prioritization factoring the impact on the system operation. The overarching framework for modeling, simulating, assessing, and mitigating attacks in a CPS is illustrated using four representative attack scenarios targeting CPES. The key objective of this paper is to demonstrate a stepby-step process that can be used to enact in-depth cybersecurity analyses, thus leading to more resilient and secure CPS.
