Published: June 2023

Abstract
With the increasing installed capacity of wind power and PV, the strong randomness of power generation makes the requirements of power systems for regulation and other ancillary services increase. However, the traditional regulation requirement prediction method cannot meet the problem of randomness on both sides of the plant and the user well. Therefore, this paper designs a regulation requirement forecasting method based on netload random distribution modeling. Combined with the hypothetical typical operation scenario of the Chinese power system in 2025, the total cost of regulation is predicted. The results show that China’s total cost of regulation can reach 10.62 billion yuan in 2025. And the sensitivity test results show that the total cost of regulation increases with the decrease of sub-period and with the increase of coverage of random fluctuation of net load.

Published: June 2023

Abstract
The regionally integrated energy system consists of multi-type energy production units, energy conversion units, and energy consumption units. This form is of great importance in the area of regenerative energy consumption and multi-type energy optimization. The optimal regulation of the regionally integrated energy system with a high percentage of regenerative energy is the key to the consumption of regenerative energy and the optimal utilization of multi-type energy. The paper presents a method which adopts multi-operating state traction control and considers both system-level and unit-level. Firstly, according to the function of each equipment, the system is classified as various units. Then the state of each unit and the system are determined by the operation data of each unit. The system allocates the unbalanced power regulation task according to the regulation ability of each unit. Finally, each unit completes the traction control according to its control parameters. In the example, the particle swarm optimization computation algorithm is applied to solve the above multi-operating state model. The results indicates that for the regionally integrated energy system, the optimal regulation can achieve the regulation effect of promoting regenerative energy consumption and reducing operation costs.

Published: June 2023

Abstract
The blade is one of the key components of a wind turbine, and the alternating fatigue load is the main factor leading to the fatigue failure of wind turbine blades. The accuracy of load determines the accuracy of the wind turbine blade test. Based on the equivalent torque time history data from the wind load acting on the blade root, the load of the two-dimensional matrix is obtained by using data compression technology and a rain flow counting algorithm. According to the capture matrix of load data, the frequency of various design loading cases and the distribution of wind speed, the symmetrical load spectrum is calculated and compiled. The fatigue load of a wind turbine blade is calculated for a certain type of 2MW blade, which lays a foundation for the design and test of a wind turbine blade fatigue loading system.

Authors: Wei Sun 
Published: June 2023

Abstract
In the field of transformer fault diagnosis, there are many diagnostic methods. These diagnostic methods are either not high accuracy or are used too long. In this paper, a dimension learning-based hunting (DLH) search strategy optimization grey wolf algorithm support vector machine (DLH-GWO-SVM) model was proposed. In the process of initializing the grey wolf population, logistic chaotic mapping was used to improve the quality of the initial wolf position. In the Wolf screening process, the DLH search strategy was adopted to solve the problem that GWO was prone to fall into the local optimal solution, and the improved Grey wolf algorithm (IGWO) was formed. Finally, the transformer fault types were classified by support vector machine (SVM), and IGWO was used to optimize the penalty factor and kernel parameter (g) of the SVM. Through the experimental analysis, the accuracy of transformer fault diagnosis can reach 95.83% after the application of the DLH-GWO-SVM model.

Published: June 2023

Abstract
Superbuck converter is a high-order converter with complex nonlinear dynamic characteristics, such as bifurcation and chaos, which will affect the stability of photovoltaic power generation systems. In this paper, the nonlinear dynamics of the voltage mode control Superbuck converter are studied. Taking reference voltage, input voltage, and output voltage error amplification factor as bifurcation parameters, the evolution process of the system from a stable state to bifurcation to a chaotic state is analyzed. The bifurcation forms of the converter under three bifurcation parameters are all period-doubling bifurcations. In this paper, the linear sliding mode control method is used to suppress and clear the nonlinear phenomenon of the system so that the converter in the chaotic state and unstable operation state can be restored to a stable single-cycle state in about 0.6ms.

Published: June 2023

Abstract
During the operation of the power grid, AC quantity acquisition plays an important role in the power system to convert analog quantity into digital quantity, which is the basis of realizing substation automation. The accuracy and reliability of sampling directly affect the reliability and stability of the whole system. Therefore, this paper studies a hybrid AC sampling technology based on frequency threshold, which is based on the sampling method. The polynomial fitting method is used to restore the power data at the time of the fault point, mainly to judge the frequency change points collected by the system and whether or not the corresponding sampling mode is switched by comparing the frequency change value with the threshold value. Finally, the advantages of the above conclusions are verified by simulation.

Abstract
In order to ensure the safe and stable operation of overhead transmission and distribution lines, the WSN network is used to optimize the line condition monitoring method design. In this paper, considering the connection mode of overhead transmission and distribution lines, a line equivalent model is constructed.

The WSN network is used to collect and transmit the operation data of overhead transmission and distribution lines, calculate the monitoring parameters such as voltage imbalance and current detuning, and finally get the visual monitoring results of line status. Compared with the traditional monitoring methods, it is concluded that the monitoring error of voltage imbalance and current detuning by the optimized design method is reduced by 1.15kV and 2.94kA, which effectively improves the monitoring accuracy of line operation.

Abstract
Considering the features of the load, such as time-varying and randomness, it is hard to estimate the harmonic impedance. The computing method of harmonic impedance is proposed with the system-side harmonic fluctuation dominated, while the phase angle is taken into account, which improves the accuracy of the calculation. At the same time, this paper adopts the idea of piece-wise linear regression to decrease the influence of unusual data on the estimation results. Finally, the theoretical validity and application feasibility are verified by an example analysis.

Published: June 2023

Abstract
The old 77 series transmission tower is widely used. In recent years, many structural damage accidents have occurred due to its inability to adapt to the changing climate in some regions. Therefore, this paper has carried out structural reinforcement in two ways for the tower designed in the early stage without considering the change of wind pressure height coefficient. In order to check the safety and reliability of the structure, a real tower experiment after two reinforcement schemes has been designed to calculate the stress of each node and component. The effectiveness of two different strengthening schemes is verified.

Published: June 2023

Abstract
The Surface Resistive Plate Counter (sRPC) is a novel RPC based on surface resistivity
electrodes, a completely different concept with respect to traditional RPCs that use electrodes
characterised by volume resistivity. The electrodes of the sRPC exploit the well-established
industrial Diamond-Like-Carbon (DLC) sputtering technology on thin (50 μm) polyimide foils,
already introduced in the manufacturing of the resistive MPGDs such as μ-RWELL and MicroMegas, that
allows to realise large area (up to 2 × 0.5 m2) electrodes with a surface resistivity
spanning over several orders of magnitude (0.01 ÷ 10 GΩ/□). Two detector layout has
been developed: the baseline layout with the DLC connected to the HV by a single dot connection
outside the active area and the high rate layout with a screen printing a conductive grid onto the
DLC film, which exploit the concept of the high density current evacuation scheme first introduced
for the μ-RWELL. Besides the use in HEP experiments as timing detector this new technology could be
exploited as thermal neutron device for homeland security applications (e.g. Radioactive Portal
Monitors for ports and airports), replacing one or both DLC electrodes of the sRPC with plates
coated with ∼3 μm thick 10B4C layer, thus obtaining neutron converters inside the active
volume of the detector. Results obtained by irradiating the detectors at the calibrated
241Am-B ENEA-Frascati HOTNES facility will be discussed.
