Drag-type vertical-axis wind turbines have a large starting torque and excellent self-starting performance, and are non-directional with respect to wind. In addition, because the maximum output occurs at a tip speed ratio of 1 or less, these turbines can be operated in a lower speed range compared with lift-type wind turbines. However, drawback of drag-type wind turbines is that their output is lower per unit sectional area than that of the lift-type wind turbines. Therefore, we have been studying the characteristics of a multi-blade drag-type vertical-axis wind turbine with stationary vanes functioning as wind direction plates. Our experimental results so far have shown that the wind turbine output is increased by using stationary vanes. In this paper, a method for calculating the output power of a multi-blade drag-type vertical-axis wind turbine with stationary vanes based on the characteristics of a single rotor blade was studied and compared with the results of wind turbine characteristics measured in a wind tunnel. In addition, the relationship between the wind incident angle of the rotor blade and the wind turbine output was examined using the proposed method for calculating wind turbine characteristics, assuming that the angle of installation of the stationary vanes are variable.

For hybrid energy systems utilizing renewable energy sources such as the power grid of Phu Quy island - Binh Thuan province, the integration of battery energy storage system (BESS) could be seen as a practical solution with remarkable advantages including economic and technical preeminence. BESS contributes to increasing renewable energy penetration, enhancing system stability and reducing the dependence on fossil fuel generation. However, the integration of BESS into an existing hybrid power system also necessitates to conduct a quantitative analysis of the performance of different solutions. This study investigates operational data of Phu Quy power grid for one year, evaluates solar energy potential and proposes a proper BESS integration solution based on a careful quantitative analysis. The simulation results show that selection of larger BESS capacity increases penetration rate of renewable energy. Nevertheless, of all proposed BESS integrated scenarios, renewable energy penetration rate as well as diesel consumption do not show a major difference. Therefore, choosing BESS also needs to consider the load capacity and time required to start and interconnect standby diesel generators.

With the increase installed capacity of wind energy, conventional generation starts to be replaced by wind farms, which will results in erosion of system frequency. It is thus imperative to develop advanced wind turbine control method to maintain the frequency. Considering the calculating complication of full-order models, this paper proposed a reduced wind turbine model with optimal dynamic performance. In order to improve the performance of the whole wind farm in frequency control, this work proposes a coordinate method at constant power control model for the goal of optimal dynamic response of the wind farm, considering the differences in operation state and wind speed of each wind turbine. Finally, the correctness and effectiveness of the proposed method are validated by the simulation.

This paper proposes a new type of Nonsingular Terminal Sliding Mode Controller (NTSMC) for a variable speed Horizontal-Axis Wind Turbine (HAWT) with a direct drive Radial Flux Permanent Magnet Generator (RFPMG). In order to have more accuracy in the dynamic models, both HAWT and RFPMG are simulated using Computational Fluid Dynamics and 3D Finite Element Method in Ansys CFX and Ansys Maxwell 3D respectively. Then, a Face Mock-Up Interface (FMI) is set up for both models which were coupled in Ansys Twin Builder. Finally, the NTSMC is applied on the DC side through a Boost Converter in order to have a less complex control algorithm which can be easily implemented on a microcontroller. Simulation Results show the performance of the proposed method and comparisons with conventional controllers in order to demonstrate its robustness and fast response.

Information system data transmission delays, packet loss, and bit errors will cause the information collected by the distribution network control center to deviate from the true value, and as the information failure problem intensifies, the original optimized control strategy cannot meet actual needs. A predictive control method considering the information failure of the distribution network under the cyber-physical fusion system is proposed. Aiming at the information failure problem in CPS, the information elements, routing model and link model are established. Then, combining with the real-time dispatching process of distribution network, a coordination optimization model of active distribution network considering information failure is proposed to minimize the cost. Predictive control model is used to adjust various distributed energy sources. Finally, through the simulation analysis of the improved IEEE33-node distribution network, the feasibility and effectiveness of the proposed method are verified, and the difference of different information failure cases is analyzed.

The fluctuation and the randomness of REG's output have severe impacts on the safety and stability of the operation. To guarantee a stable operation of the distribution system, the important impacts of the REGs on the safety operation of the distribution system are analyzed in six aspects, including the power transmission, the power quality, the frequency stability, the islanding effects, the protection,and the planning. To cope with these impacts, the corresponding suggestions, such as the formulation of a comprehensive safety and stabilization guide, the optimization of the network structure, and the improvement of the REGs' stability and controllability, are proposed.Particularly, the coordinated planning method for the distribution network is discussed in detail. The in-depth analysis of the planning model is presented.

The problem that often occurs in the field is the occurrence of soft defects that occur when installing cables due to various factors such as being pinched, punctured, or peeled. Over last year, many methods are based on non-destructive tests such as Line Resonance Analysis (LIRA), Broadband Impedance Spectroscopy (BIS). Time Domain Reflectometry, Joint Time-Frequency Domain Reflectometry is carried out. Although some of these test methods have been able to detect local degradation but to interpret the type of defect is still infancy. This work uses the BIS method with RG 58 CU cable of 33.5 meters total length. The degraded portion is done by using several types, the first is to use mechanical damage by bending beyond the cable’s tolerance limit damage, and the second is by connecting the resistance (100 Ohm) or capacitance (10nF) value using the T joint connector. The results are comparing by simulation with ANSYS Electronics Desktop. The results are the type of defect caused by the mechanical press, and the peeled parts have different characteristics. Besides, the IT transform method and IFFT method both of them can detect precisely the degraded portion at 18.5 meters long of 33.5 meters total length of the cable under test.
