Online monitoring of SF6 decomposition product SO2 gas is an effective method to monitor the internal insulation status of SF6 insulated electrical equipment. However, the measured equipment and monitoring devices can only be connected through a thin tube, the decomposition gas SO2 generated inside GIS takes a long time to reach the monitoring device, which affects the timeliness of detection. In this paper, a gas transfer acceleration measure based on external flow disturbance is proposed, and multi-physical field simulation software is used to simulate and analyze the proposed acceleration measure. In the simulation, gas diffusion and forced convection are considered. The simulation results show that the diffusion process is affected by the diameter and length of the connecting tube under the natural diffusion condition. As the diameter of the connecting tube increases and the length shortens, the diffusion speed increases; The external flow disturbance can effectively accelerate the gas transfer process, and the main influencing factors include flow velocity and disturbance times.

The unreasonable layout of charging stations will increase the investment construction cost of charging stations and affect the safe operation of the power grid. To solve the existing unreasonable charging stations layout problem, this paper proposes a multi-objective layout planning method. Firstly, the Monte Carlo method is used to predict the charging load of electric vehicles (EV) in time and space, and the prediction results are used as the conditions of primary location selection of charging stations. A multi-objective optimization model is established to minimize the comprehensive social cost and network loss. By setting the constraints of the maximum line power and the maximum voltage offset, the safe operation requirements of the power grid are achieved. Secondly, the model is solved by a multi-objective optimization algorithm and the Pareto optimal solution set is obtained. Besides, after eliminating the solutions that do not meet the safety requirements by N-1 running evaluation, the solution with the highest satisfaction is derived by fuzzy theory, which is 3572.38kCNY on comprehensive social cost and 214.35kW•h on network loss respectively. Finally, the feasibility of the model and algorithm is verified by analyzing the results.

After fault, the AC/DC hybrid distribution network can be recovered by adjusting VSC control mode and network reconfiguration, which improves the reliability and safety of AC/DC hybrid system fault recovery. The traditional method has not considered the influence of island restoration on fault restoration in AC/DC distribution network. In this paper, a fault recovery strategy for AC/DC distribution network is proposed, which is based on the dynamic coordination between isolated island and main network. First of all, when a fault occurs, select an appropriate VSC control mode, and call the energy storage system and distributed power supply in the fault area to restore power to important loads. Then taking the minimum power loss, the minimum network loss and the minimum number of switching actions as the comprehensive objective function, the ant lion Optimizer with the introduction of disturbance factor is used to obtain the comprehensive restoration strategy for the coordination of islands and the main network. Finally, the 49 node AC/DC hybrid distribution network is analyzed, and the results verify the superiority of the restoration strategy

In order to improve the efficiency and accuracy of quality testing of electronic meters, and replace the existing manual scheduling mode, automatic quality inspection job scheduling has become a natural choice for laboratories. However, different from the existing flexible job shop scheduling problem (FJSP), the quality inspection scheduling problem (QISP) has obvious differences in the correspondence between inspection tasks and batches of samples, solution constraints and the problem scale, making the existing scheduling algorithm unable to be directly applied. This paper proposes a new mathematical model for the quality inspection scheduling problem, and an adaptive hybrid genetic algorithm (AHGA). During the decoding operation, several neighborhood search strategies and heuristic rules are presented to ensure the feasibility of the solution. The elite retention strategy is introduced in the selection operation to relieve the loss of high-quality solutions. In terms of genetic operators, a mechanism for adaptive adjustment of operator crossover and mutation probability is designed to balance the global search and local search capabilities. The simulated annealing mechanism is used to speed up the algorithm's convergence and ensure the diversity of the population. Finally, the feasibility of the model and the algorithm is verified on the dataset of a state grid company.

Multiple instances of devastation caused by catastrophic natural disasters illustrate the need of strengthening the resilience of power systems. This paper proposes a preventive transmission maintenance schedule (TMS) to enhance power system resilience by improving component health before catastrophes. In the proposed optimization model, transmission line fragility is considered to determine the maintenance plan of defective lines that minimizes load shedding throughout disasters. Using duality theory, the suggested model is further transformed from a tri-level to a bi-level optimization problem. The column-and-constraint generation (C&CG) algorithm is used to tackle the corresponding robust optimization problem. Finally, the suggested model and solution technique are implemented on the modified IEEE RTS-79 system. The significant cost reductions and increased resilience verify the effectiveness of the suggested model.

The existing credible capacity of new energy mainly studies the comprehensive contribution of annual credible capacity of new energy to the reliability of power system from the perspective of sufficiency at the planning level. This paper establishes the available capacity probability model of wind power and PV power based on the probabilistic forecast, and calculates the operation credible capacity of new energy at every time under the same reliability level, and analyzes the influence factors of operation credible capacity. Besides, this paper establishes the time sequence simulation model which included the operation credible capacity into the start-up schedule of conventional units, and the new energy accommodation before and after the inclusion was calculated. The results show that, in the example, after incorporating the operation credible capacity of new energy into the unit start-up plan, compared with the traditional method, the utilization rate of new energy has increased from 93% to 95%.

In recent years, 10kV air-insulated switchgear is gradually replacing SF6 gas-insulated switchgear. In the long-term operation of the air insulated switchgear, high temperature will lead to the aging of the insulator and mechanism, resulting in serious consequences. Therefore, it is of great significance to study the temperature rise characteristics of 10kV air-insulated switchgear in different states for the promotion of air-insulated switchgear and the safe operation of power grid. In this paper, the electromagnetic and thermal coupling simulation model is established by using the multi-physical field finite element software COMSOL, and the temperature rise characteristics under normal conditions are analyzed. Then the influence of the contact resistance of circuit breaker on the temperature rise inside the switchgear is analyzed. It is found that the overall temperature rise of the A-phase conductor circuit is slightly higher than that of the other two phases. Under normal operation, the temperature rise of the lower busbar in the phase A is the highest. The increase in contact resistance caused by long-term operation will lead to an increase in temperature rise. If the contact resistance is greater than 337.5μΩ, the temperature rise of the vacuum circuit breaker contact is higher than that of the lower busbar in the phase A. The influence of the contact resistance on temperature rise is linear.

The popularity of higher education in China has significantly increased campus energy consumption. The main energy consumption is students’ use of electric water heaters (EWH)to heat household water on campuses. Analyzing and modeling students’ hot water use behavior will greatly help the research of campus water-saving and energy-saving strategies. Based on the measured data of a university in China, this study investigated the variation of students’ hot water use behavior varies by season, day of the week, time of year, and built a shower model. This study aims to determine the optimal heating strategy by using the CPLEX solver and considering the hot water supply mode of central heating distributed to each dormitory. This strategy increases consumer comfort while lowering electricity purchasing expenses for service providers.
