The energy storage station is playing an increasingly important role in supporting new power systems. How to scientifically and effectively evaluate the application effect of energy storage stations is an urgent problem to be solved. In this study, a multi-indicator evaluation model for energy storage stations is established. An improved fuzzy comprehensive assessment (FCA) with optimal weight is applied to actual energy storage stations. Using the energy storage station monitoring platform, comprehensive evaluation scores of demonstrated energy storage stations are obtained. The support effect of energy storage stations on the power grid is evaluated from three aspects: performance, operational reliability, and energy efficiency. The higher the evaluation score, the stronger the energy storage regulation ability, and the more significant the active support to the power grid. © 2023 Institute of Physics Publishing.

The power loss center is responsible for the resource loss of power grid transmission and distribution. When power loss assets fail, or projects and accounts do not match and cannot be handled in a timely manner, local problems in the power grid can quickly spread, while other links cannot be quickly adjusted, resulting in uneven power distribution and resource waste. This article outlines artificial intelligence, analyzes the factors that affect the healthy operation of power loss automation and smart grid power loss control systems, proposes an active security protection method design for fictional traps in power loss systems, and analyzes intelligent energy integrated management and control systems based on information physics systems. The results show that if an attacker attacks a fictitious grid, the system will discover and capture it, and the attack will stop. © 2024 SPIE.

With the centralized access of large-scale new energy to the power grid, the risk for the second line of defense of the new power system is prominent. The accuracy and timeliness of security and stability control strategies are challenged. In this study, an architecture of security and stability control panoramic mirror system is proposed. A new control strategy and calculation method are used to analyze the security and stability characteristics for new energy power grid. Furthermore, a real-Time closed-loop dynamic test based on Real Time Digital simulation system (RTDS) for the panoramic mirror system is completed. The results show that the real-Time simulation matching strategies are effective and correct. © 2023 IEEE.

This paper analyzes the impact of configuring a synchronous condenser on the characteristics of the inner mongolia power grid following the commissioning of the first grid-to-grid DC project. simulation results show that, after the configuration of synchronous condenser, the multiple renewable energy stations short circuit ratio (MRSCR) rises, and the DC sending end of the grid is a strong system, which is conducive to the whole scale of renewable energy transmission of inner mongolia power grid. DC bipolar blocking faults and transient overvoltage problems at the sending end occur for different operating conditions, such as reduced power and bipolar operation. Then, the effect of different numbers of synchronous condensers on transient overvoltages is studied. The study shows that it is necessary to reasonably arrange the DC project supporting thermal power unit start-up mode and configure large-capacity synchronous condenser or a certain number of distributed regulators, which can help to alleviate the problem of transient overvoltage during faults. © 2024 Institute of Physics Publishing.

The existing wireless technologies for substation operation safety monitoring include WiFi, RFID, ZigBee, CSS and other wireless positioning technologies, but due to poor positioning accuracy, it is difficult to meet the needs of applications. IoT technology has a variety of information sensors, powerful information collection and communication functions, and can provide advantages such as precise positioning. For a high-risk industry such as substations, it is also essential to monitor the safe operation of substations. Therefore, IoT technology is safe in substations. The application of operation monitoring has also become a research hotspot. In this paper, three positioning algorithms such as TOA, TDOA and AOA are proposed, and the positioning accuracy of TDOA is determined by the positioning accuracy measurement experiment. Therefore, TDOA can be selected for the positioning of the operator's position by the monitoring system. The information transmission function transmits the location information of the operator to the monitoring background. When the operator exceeds the safe area, the system will alarm and remind to ensure the safety of the personnel. © 2023 IEEE.

In power data mining, in order to cope with the rapidly growing data volume, particle swarm optimization algorithms should be improved and applied to power systems to improve performance and efficiency. In the process of particle search, the size of the particle is changed to affect the size of the ELM network structure. Such operation can not only expand the solution space of the problem, but also solve the shortcoming that traditional Particle Swarm Optimization-Extreme Learning Machine (PSO-ELM) can only find the optimal network structure in the network structure of the same scale. Experiments show that the PSO algorithm with mutation operator can converge to the optimal value more quickly. In addition, compared with the traditional ELM algorithm, Improved Particle Swarm Optimization-Extreme Learning Machine (IPSO-ELM) can obtain higher generalization performance and prediction progress in short-term power load prediction. The 4 curves respectively represent the MAPE value obtained by IPSO-ELM on the training set 1-4, and the fluctuation range is all within 4%, which proves that IPSOELM has good stability. By improving the particle swarm optimization algorithm and applying it to power data mining, the efficiency of power system can be enhanced, energy waste can be reduced, and power supply quality and reliability can be improved. © 2023 IEEE.

power system fault classification and prediction based on intelligent algorithms is a method that utilizes machine learning and data mining techniques to classify and predict fault conditions in power systems. This method can effectively prevent and avoid the occurrence of faults in the power system by collecting a large amount of power system data and using intelligent algorithms for processing to predict the type and location of faults that may occur in the power system, thereby improving the reliability and stability of the power system. This paper mainly applies the method of algorithm comparison and experiment to analyze the correlation of power system fault classification and prediction. Experimental data show that the recall rate and accuracy of the adaptive moment estimation algorithm mentioned in this article are both above 0.9, ranking first. © 2023 IEEE.

Traditional power big data processing methods can no longer meet the development trend of power big data. Designing and implementing high-performance power big data servers for real-time collection, analysis, and processing of power big data has become the development direction of domestic power big data. This article proposes a design pattern based on reactor servers. By constructing the system software and combining "data-driven"and "theoretical model"methods, the data parsing layer of the power data transmission message format based on the 104 protocol is implemented, achieving the function of changing the log printing level without the need for system restart. Through experimental testing and analysis at the end of the article, The comparison of data throughput between this system and OpenPDC has successfully verified the system's advantages in concurrency performance. The test results indicate that the throughput of this system is on average more than 20% higher than OpenPDC. © 2023 IEEE.
