The high penetration of renewable energy sources connected to the grid has brought great challenges to the frequency stability of the power system. For the combined wind/pohotovoltaic/storage power station, it is of great significance for better frequency performance to realize the coordination control of active power. Therefore, this paper presents a frequency active support strategy for combined wind/pohotovoltaic/storage power station. By establishing the model of combined wind/pohotovoltaic/storage power station, this strategy applies model predictive control (MPC) to optimize the total active power reference value and the allocation of response power of the combined wind/pohotovoltaic/storage power station. For obtaining better frequency performance, this strategy aims at absorbing wind and solar energy resources and improving the economy of energy storage station. In order to verify the performance of the proposed strategy, it is compared with droop control using MATLAB/Simulink when the load increasing and decreasing respectively. The simulation results clearly show the effectiveness of the active frequency support strategy proposed in this paper.

Real-time assessment of the risk of continuous commutation failure of the thyristor-based phase-controlled commutation direct current transmission system (LCC-HVDC) and timely preventive control measures are of great significance to ensure the safe and stable operation of the large power grid. This paper proposes a method for evaluating effective dynamic reactive power reserve of generators to deal with DC continuous commutation failure. The maximum reactive power increment of the generator corresponding to the secondary drop of the converter bus voltage is defined as the effective dynamic reactive power reserve. The effective dynamic reactive power reserve at the critical point is called the maximum effective dynamic reactive power reserve. When the system dynamic reactive power reserve is less than the reserve capacity threshold, a two-stage preventive control measure searching method is adopted. First, increase the terminal voltage of the generator and the static reactive power compensation. If the requirements are still not met, the start-up unit measures will be adopted. An example of an actual power grid verifies the effectiveness of the method. © 2021 IEEE.

The smart substation communication network is the basis for information sharing of various devices in the substation. Its operation status has an important impact on the safe operation of the substation and even the power grid. Therefore, real-time status monitoring of the smart substation communication network is becoming more and more important. Aiming at the problems of single dimension, insufficient real-time performance and manual fault analysis in existing substation communication network state monitoring technology, this paper proposes a method of smart substation communication network state monitoring and fault prediction based on network communication quality. This paper uses switch ACL technology and coloring technology to obtain communication quality indexes such as bandwidth utilization, delay, and packet loss rate in real time;based on a multi-dimensional evaluation algorithm, a comprehensive evaluation model of network communication quality is constructed;the model of the relationship between abnormal network communication quality and failures is established. Finally, real-time monitoring of network communication quality and fault prediction are realized. The application analysis in a typical 110 kV substation shows that this method can effectively evaluate the network communication quality and accurately predict failures, and can guide operationer and maintenaner to quickly restore the normal operation of the communication network. © 2021 Institute of Physics Publishing.

With the rapid growth of smart grid dispatching business scale, the traditional fat client mode power system has a large degree of business coupling, which limits the power grid dispatching business. But the lightweight man-machine cloud terminal and man-machine service framework have greatly reduced the coupling degree of the grid dispatching system business. The appearance of man-machine service reduces the development cost of client, and makes the unified browsing of multi system and multi terminal equipment easier. However, how to ensure the reliability and stability of man-machine interaction service is a question worthy of discussion. How to adapt to the interaction of a lot of clients and to adapt to the requests of different clients put forward higher requirements for man-machine service. This article describes the man-machine service architecture and key technologies to ensure reliability, introduces technologies such as load balancing and thread pools that adapt to the characteristics of power grid human-computer interaction, introduces in detail the distributed job scheduling management mechanism within the man-machine service, and describes the standardized request and return result of man-machine service. Finally, through sample testing and on-site operation, demonstrate the reliability of the man-machine service. © Published under licence by IOP Publishing Ltd.

The promotion and application of electric vehicles can effectively alleviate environmental pollution and fuel shortages. However, when a large-scale electric vehicle is connected to the power system, it brings the risk of cyber-attacks during the massive data communication process. If the cyber-attack in the data transmission process cannot be effectively detected for safety, the charging behavior will not be controlled correctly and effectively. The safe operation of cyber-physical power systems will take great risks. Therefore, the cybersecurity risks that may exist when electric vehicles are connected to the cyber-physical power system are analyzed in this article. Firstly, based on the communication structure of large-scale electric vehicles connected to the cyber-physical power system, the potential safety hazards in the information communication network of electric vehicles are analyzed. Exploring the possible cyber-attacks during the information interaction to discover the risks to the power grid caused by malicious cyber-attacks of electric vehicles.

The frequency regulation potential of temperature-controlled load aggregators means that, the total load reduction that all the aggregated temperature-controlled load users can participate in the frequency regulation. User demand response willingness refers to the willingness of users to adjust electricity consumption according to the price of electricity sales to provide demand response based on their own demand response elasticity. This paper establishes a user demand response willingness model including two parts of electricity cost change and temperature change, which is used to characterize the relationship between user frequency regulation potential and electricity price; then proposes a time series chained two-dimensional cloud generator algorithm for the willingness model to predict the temperature-controlled load operating state in the temperature-controlled load, and finally establish a two-layer model to optimize the frequency regulation potential of the temperature-controlled load aggregator, with the frequency regulation potential as the solution variable. The effectiveness of the algorithm and the model are verified through calculation examples, and sensitivity analysis is carried out.

The high reliability of smoke detectors in the electronic cabin of passenger aircraft is of great significance for reducing the false alarm rate of smoke detection and ensuring the safety of passenger aircraft and passengers. In order to analyze and evaluate the reliability of newly developed smoke detectors, a set of reliability evaluation methods for electronic cabin smoke detectors based on FMEA (failure mode and impact analysis) and Arrhenius models are presented. First of all, based on the principle of the system, the FMEA method is used to analyze and determine the potential failure location, potential failure mode and failure reason of the smoke detector. Then, the RPN (Risk Coefficient) evaluation method based on the expert scoring method determines the priority ranking of failure risks, establishes risk evaluation indicators, conducts risk evaluation on failure modes, and determines high-risk stresses. Finally, for the high-risk stress, a life prediction of the smoke detector in the electronic cabin based on the Arrhenius model is established. The feasibility and effectiveness of the above reliability evaluation method are verified and analyzed by taking a smoke detector in the electronic cabin of a certain type of passenger aircraft as an example. © 2021 IEEE.

2020 International Symposium on New Energy and Electrical Technology, ISNEET 2020

作者： Xiaobao, Liu Yuping, Zheng Feng, Long Tonghua, Wu Shuyan, Pan Lin, An State Key Laboratory of Smart Grid Protection and Control Nari Group Corporation Nanjing Jiangsu211106 China

With the rapid development of high-speed rail technology in China, the traction transformers of various types have been used more and more extensively. The differential protection of traction transformers has different differential conversion modes [1-2] which are different in their sensitivities. In this paper, taking the YNV traction transformer as an example, by comparing the sensitivities of two different common differential conversion modes and through analysis, it shows that the sensitivities of differential protection are slightly different. The sensitivities of differential protections based on different principles depend on the retention degree of differential current to the positive sequence, negative sequence and zero sequence components in the internal fault current. The sensitivity of phase current minus zero sequence differential is the highest when single-phase grounded, which completely retains all the sequence components in the internal fault current. The sensitivity of interphase differential protection is the highest when interphase fault occurs. The widely used phase current differential and phase current minus zero sequence differential do not reflect the zero-sequence component of internal fault current, which provides the basis for field fault analysis and setting. © Published under licence by IOP Publishing Ltd.

With the expansion of data centers, total consumption is growing exponentially. The center is faced with problems such as reducing power consumption, reducing costs and improving resource utilization. Reducing energy costs through monitoring is an important means of energy conservation in data centers. In recent years, more and more real-time energy consumption data are stored on the energy consumption management platform. There is a wealth of knowledge hidden in the energy consumption data in recent years. A large amount of data simplifies the traditional methods, and data mining methods have achieved good results in many fields. Therefore, it is of great significance to study a new energy consumption monitoring system and introduce data mining method into the system. © 2022, The Author(s), under exclusive license to Springer Nature Switzerland AG.
