Abstract ：
Conventional microgrids that employ droop control may experience challenges related to frequency and voltage offsets, which can pose risks to power system safety. Furthermore, the use of continuous communication in traditional control systems can result in technical and financial challenges. This paper introduces a fixed-time dynamic event-triggered secondary control for islanded microgrids, designed to achieve frequency restoration, voltage regulation and active power sharing within a specified timeframe. This distributed control approach relies solely on information from each distributed generator(DG) and its neighbours. Each DG receives communication from its neighbours and concurrently broadcasts its own information only when certain deviation were reached, thereby minimising communication costs. Several simulated instances illustrate the usefulness and robustness of this control method, including scenarios involving load changes, time delay and topology switching.

Abstract ：
This article focuses on the issue of reachable set estimation(RSE) with the consensus performance for multi-agent systems(MASs) under event-triggered scheme(ETS) and semi-Markov switching topologies with partially unknown rates(SMST-PUR). Firstly, through model transformation, the consensus research of MASs can be converted to the closed-loop stability analysis problem, and a periodic sampling ETS is employed to reduce the frequency of information broadcasting by the behavior of communicating with neighbors at the special moments. Secondly, the Lyapunov-Krasovskii functions(LKFs) with state information of time delay are constructed, whose goal is to capture more dynamics of time delay that impact on the controller's design. And a group of sufficient conditions in the aspect of linear matrix inequalities(LMIs) is derived to guarantee that the states of error system can be confined within a finite union of ellipsoid-like sets corresponding to each mode with consensus manifestation under the action of switching topology randomly governed by SMST-PUR. Simultaneously, the method of co-designing the consensus controller and the triggered matrices of ETS with RSE performance is depicted to save communication resources availably. Finally, a study case is utilized to verify the validity of the proposed method and the comparative results illustrate the advantages and effectiveness of the control algorithm designed in this paper.

Abstract ：
With the rapid development of offshore wind power and photovoltaic power generation, the importance of marine power transmission projects is increasing and the application of submarine cables is also becoming increasingly widespread. Accurate identification of the location of submarine cables is not only beneficial for routine inspections but also enhances the efficiency of fault detection. Therefore, the routing, positioning, and fault detection of submarine cables will play a crucial role in future repair and maintenance operations. The small diameter of submarine cables and the variability of internal currents have led to a decrease in positioning accuracy and an increase in positioning difficulty. To address the aforementioned issues, this paper first derives the approximate equation for the external magnetic field of submarine cables based on the underwater environment and underwater robotics, utilizing the cable structure of three-core armored submarine cables. The underwater robotic system performs attitude adjustments based on the detected magnetic induction intensity values. Building upon this, a submarine cable positioning algorithm is proposed using an improved grey wolf optimization (IGWO) algorithm. The algorithm utilizes a fitness function based on the magnetic flux density model and incorporates an online path localization method specifically designed for submarine cable detection. Finally, the accuracy and effectiveness of the IGWO algorithm are validated through simulation experiments. © 2025 Northeast University. All rights reserved.

Abstract ：
35 kV underwater cables are commonly used for the transmission of electrical energy in nearshore offshore wind farms. Investigating the loss characteristics of these cables improves in enhancing the efficiency of energy transmission. This paper presents the construction of a multi-physics coupled electromagnetic-thermal-fluid underwater cable simulation model using COMSOL software. The model aims to calculate the electromagnetic losses in each layer of the underwater cable accurately. This study examines the influences of various laying methods, seawater temperature, seawater velocity and burial depth on loss characteristics of submarine cables. The simulation results show that the electromagnetic loss of the submarine cable is spirally distributed along the cable axis. The total losses of the submarine cable increase with the increase of seawater temperature and seawater velocity. Furthermore, the losses in the shielding layer and armor layer demonstrate a decline as cable resistance surges with temperature. © 2024 IEEE.

Abstract ：
The detection and positioning of underwater power transmission cables are crucial for the operation and maintenance of marine power transmission projects. Existing location solutions are primarily based on magnetic detection via electromagnetic induction, but often suffer from imperfections and a lack of experimental validation. This paper proposes an undersea cable location method that uses a twin triple-axis coil sensor. This method is more comprehensive and feasible and can accurately calculate the relative distance and angle between the detection base array and the undersea cable. After mathematical modeling, the feasibility of the method was verified through experiments. © 2024 IEEE.

Abstract ：
With the application of distributed generators (DGs), microgrids (MGs) have gained much attention. Combined with the distributed communication of networked systems, we investigates the secondary restoration problem in islanded microgrids. The periodic event -triggered (PET) controllers are designed for voltage restoration and frequency restoration with accurate active power allocation, which can naturally avoid Zeno behavior. By means of a common Lyapunov function, a PET protocol is designed that requires only the information of neighbors for event detection. Both event -checking sampling period and event trigger parameter are taken into account to reduce computation and communication redundancy by choosing appropriate parameters. Furthermore, considering the effect of communication delay, sufficient conditions are given to accomplish the secondary control objectives with allowable delays. Switching topologies are considered in an extra discussion. Finally, the effectiveness of the proposed PET control strategies is verified by several MATLAB simulations.

Dear Editor, This letter concerns the localization of three-core underwater cables which are widely deployed for offshore energy transmission. It is a non-trivial problem, since the external magnetic field of three-core underwater cables is variable which reduces the accuracy of localization. To solve this problem, in this letter, an approximate equation is firstly derived to formulate the external magnetic field of a three-core armored underwater cable by considering the seafloor environments and the structure of three-core cables. Then, a new underwater cable localization method is proposed based on dual three-axis magnetic sensor array and the beetle swarm optimization (BSO) algorithm. The method constructs a fitness function based on the magnetic flux density amplitude and replaces the existing analytical geometry method with an optimization algorithm to achieve underwater cable localization with higher accuracy.

Abstract ：
The issue of non-fragile controller's designed with reachable set estimation and time-delay for multi-agent systems(MASs) is investigated in this paper. The information interaction among agents is governed by a set of switching sequence, which can be described by continue-time discrete state semi-Markov process. By tree-transformation, the MASs firstly converted into reduced-order system, and properly considered the instability of the parameters with the dynamic behavior of the controller, a non-fragile controller is designed to describe the system's performance cope with the perturbation from the con-troller. The sufficient conditions are established in forms of a series of linear matrix inequalities which are based on Lyapunov-Krasovskii method, and the agent's state of error systems is bounded by a finite closed set will be guaranteed. Finally, the availability of the derived theoretical results are verified by two numerical simulations.& COPY; 2023 The Franklin Institute. Published by Elsevier Inc. All rights reserved.
