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.

“…1 shows a typical grid structure which comprises a Low Voltage Direct Current (LVDC) network and a HVDC network. On the LVDC network typically Low Voltage (LV) emergency batteries and other energy storage elements, such as Electro-Mechanical Batteries (EMB) are connected together with the Electrical Power Unit (EPU) which supplies avionics circuitry [11]- [13]. On the HVDC network, High Voltage (HV) generators [14]- [18] provide the required voltage and power, together with HV batteries [11], [12] and other EPU [19], [20], which supplies electric actuators, de-icing systems and other MEA equipment [5], [21]- [23].…”

Abstract-High performance power conversion equipment is currently gaining an increasing interest for aircraft applications. In particular, isolated bidirectional DC/DC converters are often proposed for modern HVDC aircraft distribution systems. For such reason an evaluation of several isolated DC/DC converter topology is carried out considering the proposed application, interfacing a 270V DC network with a 28V DC network. A trade off evaluation has been carried out for three different topologies and an experimental prototype has been manufactured for the selected conversion architecture. Simulation and experimental results are provided in order to validate the trade off and the design of the proposed converter.

“…These microgrids often involve specialized energy management systems and technologies tailored to meet the specific demands of onboard power systems. These advancements have the potential to significantly improve the efficiency of onshore distribution systems [7], and reducing emissions from offshore and aerospace microgrids, such as all-electric ships (AESs) [8,9], is becoming a priority. The shift toward integrating multiple energy sources has resulted in the creation of multi-microenergy microgrids [10].…”

Networked microgrids (NMGs) are developing as a viable approach for integrating an expanding number of distributed energy resources (DERs) while improving energy system performance. NMGs, as compared to typical power systems, are constructed of many linked microgrids that can function independently or as part of a more extensive network. This allows NMGs to be more flexible, dependable, and efficient. The present study comprehensively investigates architecture, communication, and cybersecurity issues in NMGs. This comprehensive study examines various aspects related to networked microgrids (NMGs). It explores the architecture of NMGs, including control techniques, protection, standards, and the challenges associated with their adoption. Additionally, it investigates communication in NMGs, focusing on the technologies, protocols, and the impact of communication on the functioning of these systems. Furthermore, this study addresses cybersecurity challenges specific to NMGs, such as diverse cyberattack types, detection and mitigation strategies, and the importance of awareness training. The findings of this study offer valuable insights for NMG researchers and practitioners, emphasizing critical aspects that must be considered to ensure the safe and efficient operation of these systems.
