The half-rotating impeller tidal turbine (HRITT) is a novel tidal current turbine of combined lift and drag, which has the characteristics of high power and good start-up performance. The hydrofoil of turbines plays a vital role in the design of blades on vertical axis tidal turbines (VATTs), which have practical value for improving hydrodynamic performance. Based on the analysis of the law of moving blades on a half-rotating impeller (HRI), the design requirements of the hydrofoil of the blades on the HRITTs were put forward in this paper. Then, the effects of three kinds of hydrofoils and their thicknesses on the average power coefficient and output power stability of the HRITTs were analyzed by numerical calculation. The results showed that the rhombic hydrofoil of blades had better output power performance than the rectangular hydrofoil and the elliptical hydrofoil of blades on the HRITTs. The thickness of hydrofoils had a great effect on the power coefficient and the stability of the output power of the HRITTs.

The sensitivity of positive-sequence fault-component-based directional relays has declined when Inverter Interfaced Distributed Generation (IIDG) connects to distribution network. Theoretical analysis shows that the phase angle of IIDG equivalent impedance is not constant at 90°, which leads to a decline in the sensitivity of positive-sequence fault-component-based directional relays. For this reason, the control strategy for constant phase angle of IIDG equivalent impedance is proposed to control the phase angle of IIDG equivalent impedance to be constant at 90°, which further solves the problem that the sensitivity of positive-sequence fault-component-based directional relays declines. PSCAD is used in modelling and simulation, and the simulation results verify that the proposed control strategy achieves the expected control effect and improves the sensitivity of positive-sequence fault-component-based directional relays effectively.

Based on the analysis of two different control strategies of square wave drive and sine wave drive, the effects of the two driving modes on the performance of the permanent magnet canned motor (PMCM) are studied. The mathematical models of the PMCM under two control strategies are built, and the control mode of the motor is analyzed. The three-dimensional finite element analysis model of the motor is established, and the motor performance under the two control strategies is simulated. The motor efficiency is higher when driven by square wave. The torque ripple of the motor is smaller when the motor is driven by sine wave. It has certain engineering application value to design the control mode of permanent magnet canned motor in different applications.

Multi-agent technology is widely used in the protection and control of distribution network because of its decentralized coordination advantages, but it is limited by communication conditions and cannot be widely promoted in distribution networks where the fiber optic laying rate is not high. With the in-depth research and commercial emergence of 5G, it gives a broad prospect for the application of multi-agent technology in distribution networks. In this paper, a service restoration strategy of active distribution network based on 5G wireless communication and multi-agent technology is proposed. The multi-agent system consists of a hierarchical coordination control model consisting of Feeder Agent (FA) and Region Agent (RA). The information is transmitted using 5G communication channel. Each RA designed with suitable control architecture can implement restoration, which guarantees the celerity of restoration. By building a 4-feeder system with distributed power on PSCAD, the feasibility and effectiveness of the proposed strategy in this paper are verified.

The mechanism of the contribution of modular multilevel converter (MMC) on short-circuit current under asymmetrical fault at the point of common coupling (PCC) was studied according to operation characteristics and control strategy applied in fault. A ± 320kV two-terminal MMC system was established in PSCAD/EMTDC to verify the conclusion. Simulation results show that after fault, MMC performs as a current source at AC side because of the characteristics of the inner loop current controller. After the controllers respond, the fault current does not contain DC component. The steady-state short-circuit current is symmetrical, which can be computed by the reference value of the inner loop controller. The limits of PI of the outer and inner loop controller affect steady-state short-circuit current. The flow directions of active power of MMC before and after fault are consistent, while the flow direction of reactive power is related to the control mode and operation state. The research provides valuable guide to parameters tunning of MMC controller and relay protection.

Accurate load forecasting can improve the take-up rate of electricity, and ensure the electricity demand of residents for production and living can be met in time. A load prediction method integrated DBN and LSTM was adopted in the paper. Model used historical load data and weather data as data to improve prediction accuracy, since electricity is affected by factors mentioned above. The cuckoo search optimization was also introduced to find the best parameters for improving the prediction accuracy. The experiment result showed that the load forecasting algorithm proposed is with higher accuracy for the load forecasting compared with DBN, LSTM and DBN-LSTM.

Grid-forming control has been recognized as a flexible and robust solution for wind turbine (WT) integrating into weak AC grid in the research community. This paper investigates the damping properties of the grid-forming permanent magnet synchronous generator (PMSG)-based WT under different reactive power oscillation damping controls. First, a recently developed grid-forming control, namely, the DC voltage synchronization control (DVSC), is implemented in PMSG-based WT, enabling WT with capabilities of inertial response and grid-synchronization without the phase- locked loop (PLL). Then, two different reactive power controls, i.e., the convert er voltage control and the reactive power droop control, are further designed with corresponding damping controllers. Moreover, the impacts of associated control parameters and operating conditions on system damping characteristics are substantially and analytically evaluated, which can provide guidance for parameter tuning. The proposed damping controls stand out by: 1) fully utilizing the capacity of the converter and the reserved energy in DC capacitor to contribute to system damping support, 2) not impairing maximum power point track (MPPT) status of WT. Case studies are conducted under several power system contingencies to validate the effectiveness of the proposed damping control.

The adaptive control of manipulator based on sliding mode control and dynamic equation was originally designed and successfully applied to joint space task tracking. However, in the case of multitasking, it has not been extended in practical engineering, so the controller tends to enforce the main engineering tasks, because the parameters tend to the actual values assumed by the model. In view of the influence of multi task control and uncertain disturbance in practical engineering application, the method to deal with this situation has an important impact on manipulator control. In this paper, the transmission delay and dynamic uncertainty are modeled, the multi task constraint is introduced into the dynamics and kinematics model of the manipulator, a two-layer control is proposed, and the trajectory compensation method is introduced. Finally, the effectiveness of the proposed method is verified by simulation and simple manipulator model.

The four-switch buck-boost (FSBB) converter effectively reduces the average inductance current of FSBB when the input and output voltage is close to each other by using the four-mode operation, which alleviates the problem of limited duty cycle and low efficiency in the traditional control modes. However, the steady-state duty cycle mutation of FSBB with four-mode control will occur during mode switching, resulting in output voltage fluctuation. We analyzed the mechanism of duty cycle sudden change of four-mode control FSBB during mode switching, explored its influencing factors and governing laws, and proposed to use input voltage feedforward control to improve the smoothness of four-mode switching, so as to improve the response speed of output voltage when input voltage changes suddenly. The simulation results showed that after the input voltage feedforward control method was adopted, the four working modes can be switched smoothly in a wide input voltage range, the output voltage can be adjusted quickly, and the full load peak efficiency can reach 98%.
