Under the ambition of carbon neutrality, the new energy installed capacity witnesses rapid growth worldwide. Therefore, with the goal of minimizing load shedding and maximizing new energy consumption in zero-carbon power systems, this study proposes a probabilistic economic and adequacy evaluation method. First, the paper modeled coal-fired power plants with carbon capture, utilization and storage (CCUS) equipment, concentrating solar power (CSP) plants with thermal energy storage (TES) systems, wind power plants, photovoltaic power plants and battery energy storage systems (BESS) in the zero-carbon power system. In the coal-fired power plants with CCUS equipment, the constraints of electric power output and zero carbon emissions were considered; considering the time-series state of charge constraint, a model of the battery energy storage system was established; considering the SOC of the thermal energy storage system and power balance constraints, a CSP plant model was established. The sequential Monte Carlo simulation method is used to build the process framework of probabilistic economic and adequacy evaluation. The uncertainty of new energy sources and load, and the stochastic outage of components are all considered in the framework. The effectiveness of the probabilistic economic and adequacy evaluation method for the zero-carbon power system was verified by the in-depth analysis of the modified IEEE RTS79.

After the new energy access to distribution power grid, when new energy output is high, the power flow of the grid could be reversed probably and the overvoltage problem may be caused. In view of this, on the basis of the optimal allocation of reactive power compensation device of distribution network, this paper further introduces the demand response(DR) load, such as civil load and industrial load, to participate in the optimization. A multi-objective optimization operation method of power grid considering demand response is proposed. Based on the traditional power loss minimization and voltage deviation minimization, the new objective function is to increase the maximum utilization ratio of demand response in voltage and reactive power optimization process. And capacitors banks (CB), reactor banks (RB) and static var generator (SVG) and DR are used as control variables to optimize the voltage and reactive power of power grid, and the regulation effect is the best. Finally, IEEE 33 bus distribution system is used to test the proposed control method.

With the development of direct current (DC) distribution network, more attentions are paid to the influence of droop control strategy. Nonlinear droop control has unique advantage in the current sharing accuracy and bus voltage stability. As we know, during the operation of the DC system, the bus voltage should be stable, and the output of each power port should be reasonably distributed. However, the traditional droop control can increase the droop gains to improve the accuracy of current sharing, but at the same time, it will lead to a large bus voltage drop, which cannot meet the requirements of system in the current sharing and bus voltage adjustment rate. In this paper, related research is carried out to solve the system requirements of the above problems. First, this paper focuses on the mathematical control models of the linear. Next, analyses the advantages of nonlinear droop control. Then, this paper discusses the bus voltage drop in the load side and current sharing in the DC system. Final, this paper evaluates the line and converter loss in the efficiency of DC system and compares the different control strategies in the Matlab.

With the vigorous development of the digital age, the development momentum of data center construction is also getting stronger and stronger. The data center power supply system requires highly reliable power supply to maintain the normal operation of IT equipment, so the power supply technology of the data center equipment room is diversified. The most commonly used power supply scheme in traditional data centers is AC UPS, and the wide-scale application of AC UPS brings serious harmonic pollution to the power grid. As a new type of power supply technology, Panama power supply was born, which is a very important breakthrough for data center power supply technology. This paper studies the AC UPS and Panamanian power supply technology, builds the Panamanian power supply and the AC UPS power supply through PSCAD/EMTDC simulation software, and observes the harmonics of the two power supply technologies for analysis and comparison.

The sag and the distance to the ground of transmission lines are the main indicators of the line design and operation, and the accurate measurement of the two indicators is extremely important for the safe operation of line. Combining image processing and photogrammetry technology, a new transmission line sag measurement method is proposed in this research. The unmanned aerial vehicle (UAV)-based data acquisition system was used to take multiple on-site images from the same transmission line at different shooting positions and angles. The image segmentation algorithm combining smoothing filtering, edge detection and boundary tracking was used to identify the sag feature points in the images. The stereo image pair forward intersection algorithm was used to derive the actual coordinate value of the corresponding sag point. Then, the accurate measurement of the transmission line sag and the distance to the ground was achieved. Compared with the actual measurement results of the on-site laser rangefinder, the average error of the new measurement method was less than 1.3%, and the maximum error was less than 2.8%, indicating that the proposed method was correct and effective and could meet the needs of practical applications.

In order to achieve the goal of "Carbon Peak Reduction and Carbon Neutrality" and reduce the cost of home electricity consumption, this paper proposes a home smart energy management system (HSEMS), which optimizes home energy consumption by utilizing the photovoltaic-powered electric vehicles charging station. While ensuring the daily energy demand of home load and considering the charging/discharging demand of electric vehicles, the HSEMS energy consumption model and cost reduction strategy are implemented based on a four-stage optimization algorithm. In the proposed strategy, the profit is gained by optimally coordinating the different types of household load, the EV energy storage, parked electric vehicles charging station and the roof PV generation. Through studying the cases, the electricity cost using conventional strategy and the proposed strategy are compared and effectiveness of the proposed strategy to benefit the electricity users by saving cost and making profit is validated.

To satisfy the development demands of power grid infrastructure projects, aiming at the challenges of effective management and efficient application of numerous infrastructure projects and project cost data, this paper proposes a comprehensive utility evaluation model for infrastructure enterprise resource planning (ERP) systems, which contains two evaluation systems: performance evaluation and value evaluation of infrastructure ERP systems. First, the proposed model adopts the analytic hierarchy process (AHP) to evaluate the performance and value evaluation index system of infrastructure ERP systems and obtain subjective weights. Second, and improve the scientificity and objectivity of evaluation, the proposed model adopts entropy methods to evaluate its objective attributes. Finally, the proposed model combines subjective and objective weights to obtain the final comprehensive utility evaluation weight. The effectiveness of the proposed model is verified through a case study. The results show that the proposed model can effectively reflect the benefits and value of the system.

In recent years, the penetration of electric bicycles (EBs) is increasing rapidly in China because of their low prices and convenience. However, fires caused by battery failure in both charging and discharging procedures are reported frequently, leading to property losses and human injuries even life loss. Therefore, early anomaly detection during the charging and discharging procedure of an EB is of great significance for reducing the fire hazard by identifying its aging status and predicting faults. In this paper, we firstly define a series of features indicating the abnormal events on the data collected by the battery management system during EB discharging periods, then apply graph signal processing concepts to detect abnormal discharging events, contributing to further fault location, retrofit and life assessment on battery cells, etc. In the experiments, the proposed method is validated on thousands of discharging cycles collected in the real world under two evaluation metrics and outperforms two benchmarks based on fuzzy c-means and affinity propagation.

This paper compared and analyzed the current standards for fireproof sealing of valve hall in UHV converter station. It was found that the explosion effect was not taken into account in the design of fireproof sealing according to the current specifications. At the same time, the existing fire resistance test of valve hall was based on the standard temperature rise curve (wood stack fire), which cannot deal with the hot oil fire accompanied by explosion and high temperature in UHV converter transformer. Two modes of fire prevention and sealing failure of valve hall were proposed. On this basis, an improved design scheme including anti-explosion door and plugging fire prevention strengthening was proposed, and its effectiveness was verified by detonation impact simulation test. Finally, the evaluation system of UHV converter station valve hall fireproof sealing was proposed, including explosion resistance, fire resistance, fire weather resistance, electromagnetic shielding performance and mechanical properties.
