Aiming at the problem that the communication time-varying delay would destabilize teleoperation systems and worsen the tracking performance of robot-assisted surgery teleoperation, in this paper, a force and position predictive control method for state prediction is proposed. The Kalman filtering (KLF) algorithm is used to filter the position signal for compensating the time delay, a nonlinear Hunt-Crossley (HC) model would be used to generate a virtual environment of the remote robotic tool-soft tissue interaction at the master side, and the environment parameters would be identified by exponentially weighted recursive least squares (EWRLS) method. The system stability conditions are theoretically derived by Llewellyn's absolute stability criterion. The proposed control structure is a 4-CH architecture with state prediction, and the simulation results show the effectiveness of this predictive control method.

The sensing technology of the power system promotes the deep integration of energy network and data information and helps to build a new type of power system with deep integration of digital and system. It can ensure the stable operation of the power grid. RFID sensors are widely used as passive wireless sensors. While they still face the disadvantage of missing data information when the reader is not actively interrogated. In this paper, a shape memory polymer material is introduced and its thermo-mechanical property of deformation recovery above and below the glass transition temperature is exploited to design a temperature threshold sensor. By measuring the backscatter power of the RFID tag, whether the target exceeds the threshold temperature could be determined. This method can record historical information in a non-electric form when the reader is not actively interrogated, facilitating quick problem solving or troubleshooting. In this paper, a prototype of the SMP material was fabricated using 3D printing technology. And several reader-tag temperature threshold detection experiments at different distances were conducted. The results show that the SMP material recovers its deformation near 60 °C in the reader antenna field range. And the backscatter power amplitude of the two tags is significantly flipped. This validates the feasibility of temperature threshold sensors. When electrical equipment malfunctions lead to high temperatures, temperature threshold sensors can detect the malfunction and solve the hidden problem. © 2024 IEEE.

With the widespread application of sensors nodes in power equipment, providing a stable energy supply for these sensors has become a significant challenge. Traditional batterypowered solutions are costly and difficult to install. The development of energy harvesting technology offers a new technical approach to address this challenge. This paper mainly investigates how to enhance the energy harvesting power of Magnetic Field Energy Harvesters (MEH) under conditions where the magnetic field around power equipment is limited. A dynamic control method is proposed to improve the energy harvesting power of MEH. The fundamental idea of dynamic control is to precisely control the MOSFETs in the rectifier, dynamically adjusting the switching times of the energy harvesting interval to be symmetric around the peak current of the primary side, thereby significantly enhancing harvesting efficiency. This method is particularly applicable when the magnetic core enters the soft saturation region, causing the energy harvesting interval to be less than T/2. Experimental results show that under constant voltage load, dynamic control effectively adjusts the energy harvesting interval, maximizing the current extracted during this interval, thereby effectively increasing energy harvesting power. Compared to passive rectification, active rectification under dynamic control increases the energy harvesting power by 76%, and the power factor of active rectification is 1.7 times that of passive rectification. The research findings provide important theoretical support and practical significance for the application of magnetic field energy harvesting technology in sensor nodes. © 2024 IEEE.

When a high proportion of renewable energy is connected to the grid, the net load fluctuation can be suppressed by configuring energy storage. However, the current cost of energy storage is high. This paper proposes a bi-level optimization model that takes into account the dynamic allocation of shared energy storage (SES) capacity in response to electric load demand. The upper-layer objective function adopts EO optimization algorithm, which is to maximize the income of the shared energy storage operator (SESO). The lower-layer multi-objective function is to minimize the sum of the operating cost and the net load mean square error of multiple microgrids, which can be classified as the mixed integer linear programming problem. Then, the solution flow of the algorithm is given. Finally, under the constraints of the hierarchical optimization-based model, solving the problem by the CPLEX solver on the MATlab platform. The results demonstrate that the proposed method can allocate optimal capacity and reduce operating costs for microgrids. Simultaneously, this method increases the revenue of SESO and promotes the consumption of renewable energy. © 2022 IEEE.

The Qinghai-Tibet Plateau contains the most abundant clean energy such as hydropower, wind and solar in the world. However, it is very difficult to add overhead transmission lines on the ground due to the complex geographical environment. The large-capacity tunnel cables which is less affected by the earth surface environment, may play an important role on the energy transmission in such area. Based on the cable thermal circuit model, the electrical-magnetic-thermal multiphysics coupling of the cable is modeled in COMSOL Multiphysics. The parameter changes of the material during the temperature rising process, the influence of different ventilation conditions and different current-carrying capacities on the changes of the cable temperature field are quantitatively analyzed. The results show that the proposed model is valid in certain conditions. The research on the current carrying capacity and thermal effect of tunnel cables is of great significance for the transportation and consumption of large-scale clean energy resources. © 2022 IEEE.

This paper describes a comprehensive reviewof non-contact technologies for overhead power transmission lines. Due to ever increasing emphasis on reducing accidents and speeding up diagnosis for automatically controlled grids, real time remote sensing and actuation is the newhorizon for smart grid implementation. The technology overview with emphasis on the practical implementation of advanced non-contact technologies is discussed in this paper while considering optimization of the high voltage transmission lines parameters. In case of fault, the voltage and the current exceed limits of operation and hence real time reporting for control and diagnosis is a critical requirement. This paper aims to form a strong foundation for control and diagnosis of future power distribution systems so that a practitioner or researcher can make choices for a workable solution in smart grid implementation based on non-contact sensing.

Data-driven load frequency cooperative control for multi-area power system integrated with VSCs and EV aggregators under cyber-attacks

This paper proposes a cooperative load frequency control (LFC) strategy based on a multi-agent deep reinforcement learning (MADRL) framework for the multi-area power system in the presence of voltage source converters (VSCs) and electric vehicle (EV) aggregators under cyber-attacks. Different from the existing LFC model, a novel transfer function of VSCs is first improved by the space-vector technique and integrated with EV aggregators to develop a multi-area training environment. By installing the agent in different control areas and interacting state transition information between agents and the new environment, the MADRL-based control strategy is achieved for centralized training and decentralized execution. Thus, the proposed MADRL method can coordinate thermal turbines, VSCs, as well as EV aggregators in the different control areas. Furthermore, a suitable cyber-attack model that can circumvent bad data detection (BDD) is reconstructed according to the perspective of adversaries for the LFC system. Then the double critic networks and parameter updating policy are designed to eliminate and mitigate the fluctuations caused by cyber-attacks. The comparative simulation with other control strategies on a three-area test power system demonstrates the superior performance of the proposed MADRL-based approach.

lEC 61850 “Communication networks and systems in substation” is not only the most advanced and universal standard for communication but also a comprehensive system oriented standard for substation automation system (SAS). This paper proposes a transmission solution for communication scheme which combines Multicast Sampled Value (MSV) and Generic Object Oriented Substation Event (GOOSE) information in one network (Transmit MSV and GOOSE simultaneously with a network transmission line). MSV and GOOSE are described detail in the next context, and then the traffic flow and the delay of the two messages are estimated respectively. In this article, transmission performance tests based on the architecture of a single network are designed and implemented. The single event and multi-event tests show that the latency of the packets is quite small and the real-time performance satisfies the requirement of the intelligent substation.
