With the large-scale integration of renewable energy such as wind power and photovoltaics, the power grid now exhibits characteristics of low inertia and reduced anti-interference ability. Consequently, it presents significant risks to the frequency security of the grid. The traditional online security verification of power grid frequency encompasses two distinct working conditions. Firstly, it involves the transient frequency security verification, which focuses on the primary frequency modulation during grid faults. Secondly, it also encompasses the medium and long-term security verification, specifically targeting the secondary frequency modulation under steady-state conditions of the power grid. This method cannot consider the multi-time scales factors of power grid frequency fluctuations. An online verification method for power grid frequency security considering multi-time scales frequency modulation characteristics is proposed. Based on the sliding filter algorithm, disturbance signals of different time scales are generated for simulation verification. Simulation methods are selected based on the fluctuation levels of disturbance signals at various time scales. By considering the priority of the primary and secondary frequency modulation time sequences of the power generating unit, an online security and stability verification method for grid frequency with consideration of multi-time scale frequency response is developed. The dynamic response process of the primary and the secondary frequency modulation of the system is simulated and verified based on the IEEE-39 system.

To effectively reduce the impact of complex and severe faults on the power grid, an online verification and optimization decision-making system for emergency disposal of power grid faults has been designed. Firstly, standardize the modeling of traditional fault emergency disposal and extract the typical structure, constituent elements, and organizational approach of fault emergency disposal. A general description method for fault emergency disposal has been established to achieve structured and modular processing of data. Then, based on the actual fault handling process of the power grid and the priority of handling multiple types of safety and stability issues, the effectiveness of adjustment measures, disposal speed of control measures, control costs, and other constraints are comprehensively considered. Calculate specific control measures, control areas, and control quantities based on the stage of fault disposal. Translate rough handling points into specific control measures and suggestions to achieve online verification and optimization decision-making for fault emergency disposal. Finally, the practicality of the system is verified through an example in the article.

Interaction exists in multiple grid-forming converter parallel systems, resulting in different transient stability issues between multiple converter systems and single converter under large disturbances. During the current limiting period, the external characteristics of the grid-forming converter become current source, which causes three different external characteristic models of parallel converter. In this study, three models of parallel system were established, and the effect of different coupling power directions was analyzed based on the power angle curve. Further, the influence of different parameters of converter was discussed and three different cases of converter transient stability due to interaction was revealed. The interaction between converters is mainly determined by the coupling power direction. When the external characteristics of the converters are the same, the coupling power direction is mainly determined by the power angle. When the external characteristics are different, the coupling power direction is determined by the current limiting strategy. The correctness of the theoretical analysis was verified based on the PSCAD platform.

With the gradual increase in the proportion of new energy generation, grid-forming control with dynamic regulation and support capability of frequency and voltage has become a research hotspot. However, the current-limiting control of the converter reduces the transient stability margin and leads to the complex evolution of the transient instability mode, which poses a great challenge to the stable operation of new energy units. In this paper, the influence of different current limiting strategies on the transient stability of the single-loop voltage-magnitude controlled grid-forming converter is analyzed, and three typical instability evolution modes are summarized. Further, the influence law of virtual inertia and damping parameters on the transient stability is analyzed by critical clearing angle (CCA), and critical clearing time (CCT), the mechanism of abnormal phenomena of virtual inertia and damping parameters on transient stability is revealed based on the equal area criterion, and the conditions for abnormal phenomena are clarified, finally, the transient instability evolution modes and the mechanism of abnormal phenomena is verified by electromagnetic transient time domain simulation.

After the carbon peaking and carbon neutrality goals were determined, industrial zones with high energy consumption began investigating their own carbon emission paths and formulating carbon emission reduction strategies. According to the zone's carbon emission projections, a reasonable estimate of the long-term carbon neutrality curve can be made, which has significant research implications for describing the carbon emission path and formulating carbon emission reduction measures. This paper uses the modified Kaya identity to build a model of the zone's carbon emissions. It proposes an algorithm for the zone's carbon-neutrality path matching the carbon peak path and determines the carbon emission peak year and carbon budget of the zone for achieving carbon peaking and carbon neutrality goals.

Capacitive voltage transformer (CVT) has the advantages such as low insulation cost, small size and large electric field strength margin, so it is widely used in voltage measurement, relay protection and high frequency communication. However, CVT has the capacitors and inductors in its structure, these components are sensitive to frequency, so it can not accurately measure harmonics. Considering the stray capacitance and coupling capacitance of capacitive voltage transformer, the broadband response equivalent circuit model of CVT is established, and a cascade hierarchical analysis method is proposed to deduce the complete transfer function. On this basis, the influence of key parameters of CVT on harmonic transmission characteristics is simulated and analysed. The simulation results show that the increase of compensation reactor stray capacitance will make the resistance band move to the low frequency direction, the stray capacitance of the primary side of the intermediate transformer affects the attenuation degree of the high frequency band, and the effect of secondary side of transformer stray capacitance on the frequency response of CVT can be ignored. The results have reference significance for accurate harmonic measurement and manufacturing of CVT.

In order to better analyze the response characteristics of an AC/DC hybrid power grid with increased complexity following various types of disturbances, this paper proposes an intelligent method for clustering dynamic responses of multi-source data obtained from actual measurements or high-fidelity simulators. Base cases for AC/DC hybrid power grid planning students are created first, and a list of high-impact contingencies is searched using a graph algorithm. Then, the electromechanical-electromagnetic hybrid simulation method is adopted to create multi-source simulation data in terms of dynamic voltage, frequency, etc. An unsupervised learning algorithm and cluster analysis are then conducted to extract key features of dynamic response characteristics of the AC/DC hybrid power grid and create specific cluster labels. Advanced analysis, e.g., fast evaluation of risks from multi-source steady-state data, can then be enabled for further analysis. The proposed approach's effectiveness is verified on the actual AC/DC power grid model in East China. © 2023 IEEE.

The Low-Frequency Oscillation (LFO), Ultra-Low Frequency Oscillation (ULFO) and other oscillation can endanger the safety and stability operation of the power grid. However current relevant standards only have clear provisions on the critical damping ratio of LFO. Based on the risk of ULFO in high proportion hydropower systems, the principle and key influencing factors of ULFO are derived theoretically. According to the characteristics and hazards of ULFO, a method for determining the critical damping ratio of ULFO is explored, and the effectiveness of the method is tested through the actual response trajectory.

As a concept proposed by the new generation dispatching and control system, pre-dispatch is a control method for accurately adapting to situation changes and operational risks of power grid operation in the future. Regarding the problem of power system security assessment under pre-dispatch, this paper proposes a multi-snapshot grid operating risk points screening method. Three models based on optimal power flow are employed for power flow analysis after the power grid operating status changes, then the power grid operation trend data is obtained. And after initial risk screening, possible operating risk points are obtained to form a risk data set. The proposed model is tested in the IEEE39-node system. The risk data sets screened by the three models are identical, which confirms the validity of the proposed model. The proposed method for screening operating risk points can provide dispatchers with a wide range of online auxiliary decision support.
