In order to improve the absorption ratio and realize the efficient utilization of renewable energy, a source-load coordinated two-layer optimal dispatching model is established in this paper, which considering the participation of high energy load in absorbing wind power and photovoltaic power (wind-PV power). In the upper-layer optimal model, the minimum system operation cost of the system and the maximum amount of wind-PV power absorption are taken as the objective functions. And an improved Harris Hawks Optimization is adopted to solve the upper-layer model. In the lower-layer optimal model, the high energy load is used to absorb the blocked wind-PV power calculated by the upper-layer model. Finally, by analyzing the dispatching results, it is concluded that the proposed two-layer optimal dispatching model can effectively reduce the total cost of the system. The high energy load enterprises will gain profit while participating in wind-PV power absorption. The simulation verifies the effectiveness of the proposed optimal dispatching model.

Composite transmission towers have become a key trend in the development of transmission and substation systems in recent years, and composite cross-arms have begun to replace traditional steel cross-arms in some lines. The interface of composite cross-arms, on the other hand, might be faulty owing to its variables and external environmental influence. Existing detection technologies have several limitations, and active infrared thermography, as a new technology, has demonstrated its efficacy in identifying faults in composite materials. In this work, the thermal response characteristics of composite cross-stretcher interface flaws are comprehensively investigated using the finite element simulation method. The thermal response characteristics of interface defects of various sizes, depths, and kinds are compared, and the temperature variation characteristics of the defects are described using linear and logarithmic coordinates. The nature of the defect can be extracted from the rate of temperature change and the temperature in the smooth phase in linear coordinates, and the nature of the defect can be extracted from the curve shift time, magnitude, and direction in logarithmic coordinates. The research presented in this work demonstrates that active infrared thermography can effectively distinguish interface defects in composite cross-arms.

In view of the problem of flood disaster caused by heavy rainfall, which affected power supply reliability, a dynamic prediction approach for power supply area interrupted by heavy rainfall is proposed. First, under the spatial correlation rules, the power supply area within the surface rainfall boundary is judged by multidimensional data, such as digital geography. Secondly, with the distribution transformer of the power supply area as the geometric center, the area and the scale of power outage users are solved. Thirdly, the supervised learning algorithm is used to predict the disaster area out of service, on the basis of the binary classification of prior data. Finally, the dynamic changes of the predicted results are calculated according to the intensity changes of the rainfall process. Using the confusion matrix and the receiver operation characteristic curve to verify the prediction method. The numerical results show that this approach can dynamically predict the power supply area interrupted by heavy rainfall, which can be used for the production command in the process of “water rise and power failure, water back and power recovery”.

The requirement for primary frequency regulation (PFR) capability of thermal power plants (TPPs) in power systems with larger penetration of renewable energy resources (RESs) is higher since the RESs contribute less to PFR compared with TPPs. To ensure the system frequency stability, this paper proposes to enhance the PFR capability of TPPs through integrating energy storage systems (ESSs) into them. By applying the PFR control strategy to the ESS, the fast response capability of the ESS is utilized, and the overall response speed of the power plant integrated with an ESS can be significantly improved. Furthermore, the state of charge (SOC) of the ESS is kept within the permissible range during the operation by adopting an energy recovery strategy to restore the released energy for PFR periodically. The effectiveness of the proposed control strategy is verified by simulation results.

When the traditional droop control is applied in the islanded microgrid system, the uneven distribution of reactive power in the system is caused by the different line characteristics of transmission lines. Based on the analysis of the traditional droop control theory and the reactive power distribution principle, an improved droop control strategy to realize the reactive power distribution is proposed. The line characteristic curves of different transmission lines are adjusted to make them intersect at one point, with a fixed droop characteristic curve. Firstly, a small voltage perturbation is injected into the system to obtain the observed line impedance, and then the reference voltage is compensated. Finally a simulation model is built with the MATLAB/Simulink software. The accuracy of the line impedance observer and the distribution effect of the reactive power in the islanded microgrid are verified with the simulation experiment.

In this paper, the influencing factors of planning reserve capacity under the background of constructing the new type power system are analyzed in depth. Considering the influence of the confidence rate and different error coefficients of the renewable energy prediction, two correction methods of load reserve capacity were proposed. At the same time, the influence of UHV DC project production on the hot accident reserve was considered in this paper. The changes of the planned reserve capacity of the power system for large-scale renewable energy access and DC project commissioning are studied. Taking a regional power grid as an example, the recommended value of reserve capacity of regional power grid and provincial power grid at different levels in different years was calculated under the condition of high proportion of renewable energy access. The research conclusions make important significance on accurate analysis of power system balance and reasonable guidance of future power supply planning and layout.

Transmission safety and capacity of overhead transmission lines are important for the electric power system. Icing seriously threatens the security of power delivery, reflected in the line galloping and line-tower collapsing. Here, novel anti-icing aluminum (AI) conductors with different diameters were successfully prepared by anodization techniques. The superhydrophobicity and glaze icing behavior of all specimens were verified. Furthermore, the transmission capacity of prepared Al conductors was evaluated by up- current experiments. Line loss of all Al conductors was calculated and determined by mathematical formulations. Results show that anodized Al conductors exhibit good anti-icing properties and increased transmission capacity, attributed to the superhydrophobicity and heat dissipation of the nanopores micro-structure. The good anti-icing properties and large transmission capacity make the anodized overhead transmission line the potential low-cost candidate to improve transmission safety and capacity.

Due to the unclear feature information of single-phase grounding faults in the active distribution network and the influence of fault conditions and environmental noise on existing route selection methods, this paper proposes a route selection method for active distribution network faults based on dilated convolution and the attention mechanism. Firstly, form two-dimensional time-frequency graphs mapped from the zero-sequence current by using wavelet transform. Then, construct a dilated convolutional network model based on the attention mechanism, combine it with the softmax classifier, and train the network model. Finally, the effectiveness of the proposed method is verified by comparison of simulation and experiment. The results show that, when the accuracy reaches 95%, the network constructed in this paper takes 179s less than ordinary convolution, and the accuracy increases by 3.3% under the same training time.

The motor operating mechanism helps to meet the requirement of intelligent operation of high-voltage circuit breakers. However, the current motor operation mechanism needs motors with low inertia and large torque to meet the opening and closing speed requirements, which limits the development of motor driving circuit breakers to high voltage level. In order to reduce the torque demand of the motor operating mechanism, this paper studied the feasibility of applying 252kV double-motion arc extinguishing chambers to the motor mechanism, and the relative displacement between two contacts and the torque curve during the opening and closing operation are calculated. The results show that the motor operating mechanism with double-motion mechanism can meet the speed requirements of the 252 kV circuit breaker. Compared with the single-motion mechanism, the demand for the maximum motor torque can be reduced by nearly 25%. The research shows that double-motion mechanisms help to reduce the torque requirements, which provides the possibility to apply the current motor driving circuit breakers to higher voltage levels.
