“…In [28], the authors provide an in-depth literature review of the vulnerabilities, countermeasures, and test environments associated with Grid-Connected Power Electronics Converters (GCPECs). From the review and the analysis, it is found that GCPEC vulnerabilities include both cyber and physical layers that are easily accessible to malicious hackers.…”

This work demonstrates the feasibility of using Kali Linux in the process of power electronic device research. The novelty in this work is the use of Kali Linux in the process of power electronic device research. This operating system is mainly used for the penetration testing of various communication devices but not for power electronic device research. The aim of this work is to study the level of network security (the type of security vulnerabilities that a power electronic device has) and whether the data exchange between the power electronic device and the monitoring and control center is secure. Additionally, penetration testing has been carried out. Kali Linux was used to implement these tasks. Penetration testing was performed to verify how the studied power electronic device reacted to various TCP DoS attacks—could it be accessed, was it blocked, etc. Kali Linux and some of the tools built into the operating system—Nmap, hping3, Wireshark, Burp Suite Community Edition—were used for this study. During the penetration tests, a characterization of the traffic being processed/generated by the studied power electronic device was carried out to evaluate and analyze what impact each TCP DoS attack had on the device’s performance. In order to conduct the study, an experimental setup was designed. This experimental network was not connected to other networks, so the cyber attacks were controlled and confined within the experimental network. The research carried out validated the use of Kali Linux for the study of power electronic devices. From the obtained results, it is found that the studied power electronic device provides a certain level of network security, but the data exchange is insecure.

The existence of imbalanced single-and two-phase loads, coupled with short-circuit faults, contributes to voltage imbalance. It is inevitable to use LCL filters to remove harmonics caused by converter switching. While effective in removing harmonic components, these filters may inadvertently amplify and propagate resonance. Both voltage imbalance and active resonance significantly degrade power quality. This paper proposes a multi-level hierarchical control system to mitigate both phenomena. At Level 1, the controller incorporates proportional-resonant regulators for current and voltage. Level 2 employs common droop control to establish microgrid voltage and frequency reference values. Level 3 introduces a washout filter with an adjustable Kd gain, capable of attenuating active resonance harmonics originating from the LCL filter. Finally, Level 4 integrates a controller based on extracting positive and negative sequence components using the dual decoupled synchronous reference frame (DDSRF) algorithm. This controller effectively compensates for negative sequence components of voltage in the load bus, balancing load voltage. Simulation results for a standalone microgrid demonstrate that the proposed 4-level hierarchical control algorithm can reduce the load bus voltage imbalance from 10% to 2.5% under the most challenging conditions. It diminishes harmonic distortion caused by active resonance from 11% to 2.5%. The presented control algorithm can perform optimally under dynamic changes of active and reactive power of nonlinear and imbalanced loads. The main merit of this approach is not to use physical devices and Flexible Alternative Current Transmission Systems (FACTS), such as Active Power Filters (APF), Distribution Static Synchronous Compensators (DsSTATCOM), SVC.INDEX TERMS Active resonance damping, Hierarchical control, Islanded microgrid, Unbalanced voltage.
