The substation is the core facility of the power system. The interaction and coordination of different equipment in the protection and monitoring system(PMS) directly affects the working efficiency and stable operation of the system. However, the current protection and monitoring system of substation(SPMS) generally lacks evaluation method for collaboration. To the above problems, this paper proposes an evaluation method for collaboration in S-PMS based on the G1 method. Firstly, according to the requirements of the coordination for PMS, the corresponding indicators are proposed to form the index system for evaluating the coordination. Then, combined with G1 method, a comprehensive collaboration evaluation model is constructed. Finally, the coordination of two different structures of substations is evaluated and analyzed, and the feasibility of the evaluation method is verified. © 2023 IEEE.

This paper investigates dynamic voltage restorers (DVRs) as a solution to voltage-based power quality issues. A control algorithm based on a Multilayer Gamma Filter is proposed to compensate for voltage sag, voltage swell, distortions, and phase voltage discrepancies caused by various factors in series-connected devices. To improve power quality, the proposed Multilayer Gamma Filter-based control algorithm is used for the compensator. In several ways, the Multilayer Gamma Filter outperforms traditional filter designs. To begin with, it is adaptive, which means it can change its parameters in response to various types of disturbances. Second, it has a lower computational complexity than other filters, making it a more efficient option for real-time applications. Finally, it has a high accuracy in estimating input signal parameters and a fast transient response. The system performs satisfactorily even under less-than-ideal conditions with wide voltage and load variations. The control algorithm employs two proportional integral (PI) gains to maintain the dc link voltage and terminal voltage stable. The gains of the PI controllers are critical for estimating reference load voltages correctly. The salp swarm optimization algorithm is used to optimize DVR gains. The salp swarm optimization algorithm has been demonstrated to be effective in PI tuning, providing faster convergence and improved performance over traditional tuning methods. The control system can achieve better regulation of the process variable and overall system performance by optimizing the PI gains. The optimized gains are applied to a fourth-order multilayer gamma filter to extract reference load voltages. To extract reference load voltages, the optimized gains are applied to a fourth-order multilayer gamma filter. © 2023 IEEE.

With the promotion of the strategic goal of 'carbon peak and carbon neutrality' and the gradual development of new power system construction, new energy represented by wind power and photovoltaic continue to develop rapidly. The strong uncertainty and randomness of large-scale new energy pose a huge test for the safe and stable economic operation of the power system. Firstly, this article analyzes the model of the joint system of new energy and energy storage. Secondly, it analyzes the application scenarios on the power generation side, including scenarios where the energy storage system suppresses minute level fluctuations in new energy power plants, reduces prediction errors in new energy power plants, and increases power generation revenue from new energy power plants. Finally, this article analyzes the application scenarios on the power grid side, including those involved in peak shaving and frequency regulation of the power grid. The research conclusion of this article indicates that the combined system of new energy and energy storage can suppress minute level fluctuations in new energy power plants and reduce prediction errors of new energy power plants. The energy storage can meet the active power balance of the power grid, alleviate peak valley differences, and quickly mediate to meet the frequency regulation needs of the power grid. © 2023 IEEE.

A battery energy storage controller (BESC) can balance the mismatch of power demand and supply and improve flexibility and resiliency of seaport microgrids. However, it is required to test functionality of the BESC, and validate that it can balance the power supply-demand imbalance by charging and discharging the battery. The main objective of this study is to implement hardware-in-loop (HIL) tests for validating the controller's functionality. This article investigates the testing performance of the BESC that will be used in harbour grids to adjust for the mismatch of power supply and load demand by appropriately charging and discharging the battery energy storage system. The proposed BESC can effectively save energy and reduce peak load demand in harbour grids with limited transmission and distribution network power capacities. The BESC is initially developed offline in MATLAB/Simulink and then implemented in a FPGA based external controller interfaced with the OPAL-RT real-time simulator by using the IEC61850 communication protocol and GOOSE messages. The BESC is configured and implemented on the external FPGA board. In addition, real data from the local distribution system operator Vaasan Sahkoverkko and the harbour operator Kvarken port of Vaasa have been utilized to evaluate the efficacy of the suggested control algorithm for the battery energy storage system with a realistic scenario. The simulation findings indicate that the BESC can balance electricity demand within the microgrid by charging and discharging batteries. (c) 2023 The Authors. Published by Elsevier Ltd.

A spatial non-cooperative target point cloud feature extraction method based on deep learning is designed for the characteristics of weak geometric information of noncooperative targets. A convolutional neural network model is used to learn and fully exploit the non-cooperative target surface geometric information in a data-driven manner to obtain a local feature descriptor NCPD (Non-Cooperative target Point Describer), which solves the existing problem of insufficient descriptiveness of manual local geometric features. The matching test results in the non-cooperative target point cloud sequence show that the proposed local descriptor outperforms FPFH, SHOT, VoxelNet, PointNet and other methods in terms of descriptiveness and robustness. © 2023 SPIE.

At high angular velocity, the signal-to-noise ratio(SNR) of star image may become very low due to star point tailing, which leads to the decline of the star extraction rate. To solve this problem, an adaptive star extraction algorithm is proposed in this paper. Firstly, the star image is divided into several blocks, and the adaptive global threshold method is used in each block to get the gray extremum of each block. Then, the weight matrix of the star under the current angular velocity is obtained adaptively by Kalman filter. For the selected extreme pixel, the background threshold of the pixel is obtained by using the maximum background estimation method according to the calculated weight matrix. Finally, region growth is carried out in the eight neighborhood of the current pixel until all the star pixels are extracted. The experimental results show that this algorithm can extract stars in images taken at high angular velocity, and the extraction rate is higher than that of the traditional scanning method, which proves the algorithm is effective and has good robustness. © 2023 SPIE.

The tilt of the leveling ship in the leveling process has to meet the high precision process requirements while at the same time minimizing the actuator action frequency in the control process and extending the actuator life, which is very important for leveling processes with time delays and complex external disturbances. A group of advanced control strategies must be designed to match them. Firstly, a ballast leveling mechanism model is established based on the hydrostatic characteristics of the ship, followed by the design of a multi-switch device predictive control algorithm. By making the rolling time domain larger than the maximum time delay and ensuring that the switchgear combination is constant in the time domain, LESO is introduced for online prediction of unpredictable disturbances and rolling optimized predictive control of the equipment combination, the influence of time delay and external disturbances on the control system is weakened, and the switching frequency of switchgear is reduced. In the final simulation, the tilt tracking RMSE was reduced by 22.2% compared to conventional switching control, and the number of actuator switches was reduced by 6%. © 2023 SPIE.

Photovoltaic power generation system can not participate in the friendly interaction of power grid because of the lack of inertia damping. Virtual synchronous Generator (VSG) technology is an effective means to solve this problem. However, moment of inertia of technology based on virtual synchronous machine set is too large or too small are not conducive to the stability of the system frequency, based on the analysis of virtual synchronous machine running mechanism, this paper proposed virtual synchronous machine inertia adaptive control strategy, according to the load disturbance caused by frequency variation, the real-Time dynamic adjust the moment of inertia, and thereby avoid frequency rapidly rising and falling. Finally, the effectiveness of the theoretical analysis is verified by MATLAB/Simulink simulation. © 2023 SPIE. All rights reserved.

Considering the carrier landing task for a canard UAV, an adaptive control scheme is presented based on multivariable model reference adaptive control (MRAC) method. The UAV will suffer from external and internal disturbances during the landing process. The external disturbance includes the airwake and deck motion, while the internal disturbance denotes its own actuator failure. Simulation demonstrates that the proposed structure can improve tracking accuracy, rapidity, and robustness of glide path and attitude. © Beijing HIWING Scientific and Technological Information Institute 2024.
