With the rapid development of today's economy and society, people put forward higher requirements for power quality. In the process of distribution network operation, if there is a fault, it will produce immeasurable loss. It is necessary to restore the power supply in the non-fault power outage area in time. Therefore, it is particularly important to restore the power supply of distribution network quickly and efficiently. This paper considers factors such as load recovery, switching operation times and network loss. Based on the mathematical model of distribution network restoration and reconstruction, a genetic algorithm for distribution network power supply restoration and reconstruction is proposed. Combined with the characteristics of distribution network, the crossover rate and mutation rate suitable for distribution network are selected to improve the efficiency of the algorithm and make it quickly converge to the global optimal solution. Finally, the feasibility of distribution network is verified by an example. © 2021 IEEE.

The structure of intelligent substation SCD file is complex, and there are many layers of information. Different functions have corresponding information basis, and often need to be associated across multiple information nodes, resulting in poor visualization. This paper presents a multi-dimensional visualization method of SCD file information of smart substation based on knowledge graph. Firstly, the file structure and function structure of SCD text expression are analyzed. Then the SCD file node is extended and the seven-step method is adopted to construct the intelligent substation ontology, which is realized by Protégé. The knowledge graph of substation is constructed by using ontology and relationship between SCD nodes. The graph expression of SCD is completed, and the visualization of file structure information is realized. The information path of functions such as the correlation between primary and secondary devices and the correlation between virtual and real circuits is mined. The information nodes in the path are searched in the SCD knowledge graph to realize the visualization of functional structure information. The above work was done through Neoj4, Python. The simulation results show that knowledge graph can decouple SCD information and realize multi-dimensional visualization of information with a high degree of visualization, which can provide guidance for operation and maintenance and information retrieval.

As China pursues its "carbon peak" and "carbon neutrality" goals, the rapid growth of renewable energy has raised concerns about grid stability due to transient overvoltage. The overvoltage can exceed protective settings, leading to disconnections of renewable sources. This paper investigates the mechanisms behind transient overvoltage in a large-scale radial wind power integration system following a three-phase short-circuit fault. By modeling a large-scale wind power sending end system with both grid-following (GFL) and grid-forming (GFM) converters, the study analyzes turbine dynamics and quantifies transient overvoltage. The research also examines the factors influencing overvoltage, providing a theoretical foundation for overvoltage protection in wind power systems.

An assessment method of cascading failure is proposed to acquire high-risk cascading failures chains under high penetration of renewable energy power system. At first, a dynamic simulation model considering the controller of DFIG is established, and the simplified LVRT model is proposed for the DFIG response model. Then, a risk index is defined for the depth first tree search method used in searching proceeding. Finally, a searching method for cascading failure based on dynamic simulation and power flow is presented, which can simulate the interactive between DFIG and grid failure. The effectiveness of the method proposed to search high-risk cascading failures chains under high penetration of renewable energy is verified by the simulations concerning the modified New England test system. © 2021 IEEE.

With the development of renewable energy sources, the scale and complexity of power systems are continuously increasing, resulting in a high requirement for the efficiency of dynamic simulation. To enhance the overall simulation speed, this paper proposes an adaptive internal time-step adjustment method of elementary transfer function blocks for Trapezoidal integration in power system dynamic simulations. For blocks with different time constants, three integration modes are defined, including single-step integration, multiple-step integration, and static approximation. Each block can select an appropriate integration mode and adaptively adjust its internal time-step. Implementation of static approximation for blocks with small time constants is given. The proposed method is applied to the open-source Simulation Toolkit for Electrical power systems (STEPS). The IEEE 9-bus test system is tested to obtain the maximum simulation time-step that can maintain numerical stability and validate the efficiency of the proposed method.

The overall load profile tremendously changes due to the charging of abundant electric vehicles (EVs), which brings challenges to the active power balance of distribution network. To achieve smaller fluctuation of the interactive power between the distribution network and the bulk grid, a rolling scheduling strategy of EVs based on dynamic clustering and variable horizon is proposed in this paper. First, a clustering criterion for EVs is formulated to reduce the computational complexity, and the EVs are re-clustered after each scheduling. Then, the scheduling model considering the minimum variance of comprehensive load profile and the minimum charging cost is established, whose purpose is to optimize the charging and discharging plans of the EV clusters. The scheduling horizon is the variable continuous period, which is between the starting time of the current execution horizon and the departure time of each cluster. Finally, the simulation results of modified IEEE 33-bus system verify that, the optimal EV charging and discharging plan can perfectly coordinate with the photovoltaic output profile while maximizing user satisfaction, which significantly reduces the peak-valley difference of the equivalent load. © 2023 SPIE.

With the increasing penetration of renewable energies, the power system inertia is decreasing, and there is an urgent need for wind and PV generations to participate in frequency response. PV units are stationary power generating units and usually work in maximum power tracking mode. It is difficult to provide inertia support to enhance the power system frequency characteristics. Therefore, this paper proposes a frequency control strategy based on the DC capacitor energy storage on the high voltage side of PV generation, using its transient discharge process to make it participate in the frequency response. Considering the limited energy stored in the capacitor, droop control and virtual inertia control are added to the electrochemical energy storage for inertia compensation, and a cooperative inertia control strategy is proposed for PV and energy storage system. A case study is carried out to verify the effectiveness of the proposed control strategy. © 2022 IEEE.

Using modular multilevel converter-based multi-terminal high voltage direct current (MMC-MTDC) transmission to integrate large-scale renewable power into the main power grid is an important development trend in China. To cope with the stability issues under weak grid conditions, different grid-forming control strategies have been proposed for the MMC in MTDC transmission systems. These control strategies have different structures due to different control targets and are difficult to unify. To solve this problem, a novel grid-forming control structure is proposed in this paper. The MMC emulates the synchronous generator (SG), and the submodule capacitor voltage emulates the SG rotor speed. On this basis, by utilizing the modulation control degree freedom, a unified DC-side controller is proposed to realize different control targets. Finally, the simulation model of a 4-terminal MMC-MTDC transmission system with renewable power integration is established in the PSCAD/EMTDC. The effectiveness of the proposed strategy is verified by the simulation results. © 2024 IEEE.

With the use of photovoltaic (PV) generation, a large number of synchronous generation units have been replaced, resulting in obvious decline in the equivalent inertia of power system. Facing a lack of inertia, virtual inertia control techniques are applied to PV, but there is a lack of methods to estimate the equivalent inertia of PV in real time, making it difficult to quantitatively estimate the effect of control method with virtual inertia. Therefore, this paper adopts the controlled autoregressive (CAR) identification model and the recursive least square algorithm of dynamic optimal forgetting factor (DOFF-RLS) to estimate the PV equivalent inertia, in order to address the time varying characteristics of the PV equivalent virtual inertia. The proposed identification model and solution algorithm have superior tracking capability and good convergence. All that is required is to obtain the disturbance data of frequency and active power from the point of common coupling from the phasor measurement unit (PMU). Finally, the accuracy and suitability of the identification model and method are verified by simulation. © 2022 IEEE.

With the increasing penetration of renewable energy, the fluctuation of renewable energy source (RES) is one of the most important factors that affect the reliability and economy of power system. It is crucial to consider the flexibility and reliability in planning stage. In this paper, a grid-load-storage coordinated planning model considering unit commitment (UC) constraints is proposed, in which the candidate transmission lines and energy storage systems (ESSs) are simultaneously planned by minimizing the investment cost, operation cost, flexibility cost and wind and load curtailment cost. The flexibility resources are provided by generators, ESSs and demand response (DR) together. In order to ensure the reliability of this model, N-1 security criterion is also considered. To validate the effectiveness and superiority, the proposed model is illustrated using the IEEE-RTS system. © 2021 IEEE.
