The power system becomes more complex, due to the high penetration of renewable energy and more electronic devices are integrated to the traditional grid. SSCS is the critical task for power grid operation to ensure the control reliability and effectivity. It is inevitable to improve verification experiment technology for SSCS considering the development trend of the power system. RTDS is a powerful simulator for power system which is able to reflects the practical power system operation in real time. In this paper, a method for status tracking of power system model in RTDS is developed that SSCS is able to be verified under multiple operation conditions. It is found that the status cannot be tracked consistently as given, due to the limitations of RTDS models and raw data. The limitation in tracking reactive power output of generators is overcame in this paper. Besides, the development trend of online stability analysis and control is discussed as well as SSCS verification experiment technology. © 2021 IEEE.

With the characteristics of low loss, low harmonic content and large transmission capacity, voltage source converter based high voltage direct current transmission (VSC-HVDC) has become the focus of the development for large-capacity and long-distance power transmission system connected with offshore wind farms. However, since the power supplies on both sides are controlled, the fault characteristics are changed, and the performance of the traditional distance protection is influenced. Based on the control strategy, the amplitude and phase angle of the equivalent positive and negative sequence impedances at the two sides of the transmission line are analyzed, and the current phasor expressions of the wind farm side and the VSC-HVDC side of the faulted line are derived. Then the adaptability of distance protection using power frequency component (DPPFC) of transmission line for VSC-HVDC-connected offshore wind farm is analyzed under different fault conditions. The results show that the amplitude and phase angle of the equivalent positive and negative sequence impedances of the wind farm and the VSC-HVDC system are affected by the control strategy of the converter and the fault conditions. The DPPFC is not suitable for VSC-HVDC-connected offshore wind farm system. The ability to avoid the effect of fault resistance of the DPPFC at the wind farm side gets worse. The simulation conducted by EMTP-RV verifies the effectiveness of the analysis.

This paper presents an advanced out-of-step (OOS) splitting protection simulation platform considering high frequency generation tripping and low frequency load shedding. In the proposed simulation platform, Real-Time Digital Simulator (RTDS) is utilized as the real-time power system simulator. Through the high-speed I/O card, real industry OOS splitting protection device is integrated into the proposed simulation platform. Based on the real China South power grid (CSG) control strategy, high frequency generation tripping and low frequency load shedding components are modelled in the simulation. CSG real grid is modelled in the RTDS to perform the Real-time hardware-in-the-loop simulation. Simulation results present that there is a clear difference between with high frequency generation tripping results and without high frequency generation tripping results.

With the increase of wind and solar renewable energy penetration in power system, the frequency control ability of power system completely depending on traditional power supply has weakened. This actuality requires that renewable energy stations should be equipped with a certain amount of energy storage to improve the primary frequency control ability. This paper considers the fast response ability and flexible control of energy storage for both charging and discharging, as well as its unique frequency response characteristics. Firstly, the control characteristics of the primary frequency regulation of the hybrid wind-solar-storage power station(Wind-PV-ES) are analyzed. By improving the automatic generation control(AGC) strategy of the hybrid Wind-PV-ES power station, a coordinated control strategy for the primary frequency regulation of the hybrid Wind-PV-ES power station is proposed for different frequency ranges based on the improved AGC control. After the primary frequency regulation action, the energy storage output is given priority control before wind and solar. When the energy storage active margin is insufficient, use the frequency regulation capacity of wind and photovoltaic power system to improve the primary frequency regulation capacity of the hybrid Wind-PV-ES power station. The control strategy proposed in this paper can improve the primary frequency regulation capability of renewable energy station. Finally, the paper verifies the effectiveness of the proposed control strategy through simulation.

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.

10kV distribution lines have low lightning withstand level and are easily affected by direct lightning or induced lightning, leading to insulator flashover or even tripping. In order to study the influence of insulated cross arm on the lightning withstand level of 10kV overhead distribution line combined with the actual situation, this paper first built a 10kV distribution line model, carried out lightning impact comparison test of insulated cross arm and iron cross arm, and obtained the lightning impact insulation strength of tower U50% under different cross arm types. Then, the numerical calculation method of lightning induced overvoltage of 10 kV overhead lines is proposed, and the self-defined lightning induced overvoltage calculation model is established by using MODELS language. Combined with the actual situation of 10kV power supply line of an oil transmission station in southern mountainous area, a co-simulation model of direct lightning strike and induced lightning overvoltage of 10kV distribution line was established by using ATP-EMTP, and the improvement effect of insulation cross arm on lightning resistance level was quantitatively analyzed. Finally, the effect of the device to improve the level of mine resistance is verified by the actual operation. The results show that replacing the iron cross arm of the cement tower with the composite insulating cross arm can significantly improve the lightning impulse insulation strength of the tower by U50%, which has the most significant effect on improving the lightning withstand level of the induced lightning of the line, followed by the lightning withstand level of the top of the lightning rod tower, and the lightning withstand level of the lightning stroke line has little improvement. The research results can provide reference for lightning protection design and transformation of distribution lines.
