As the high-quality flexible resource of the grid, electric vehicles (EVs) can provide multiple auxiliary services for the grid at the same time. However, due to the one-way charging and discharging of EVs, as well as the limitation of power and capacity, which may cause availability conflicts when EVs participate in different auxiliary services simultaneously. This paper focuses on the analysis of the conflict mechanism of EVs participating in the secondary frequency regulation and peak shaving ancillary services at the same time. The impact mechanism between different auxiliary services in this conflict mode is revealed from the two aspects of limit conflict and charging and discharging instruction conflict, and the results of availability conflict of the two types of auxiliary services are verified and analyzed through simulation examples. © 2023 IEEE.

Wind turbines generally adopt the maximum wind energy tracking control strategy, which makes them obtain the best power generation efficiency. However, this makes wind turbines unable to respond to changes in system conditions, provide inertial support for the system, and participate in the primary frequency modulation of the system, which brings challenges to the frequency safety of high-proportion new energy power systems. In order to improve the frequency stability of high-proportion new energy power system and make wind turbines participate in frequency control actively, this paper proposes a primary frequency modulation control strategy based on load reduction for doubly-fed wind turbines. According to the aerodynamic characteristics of variable pitch wind turbine, a coordinated load shedding control strategy combining variable pitch and variable speed operation was proposed to make the wind turbine have active power reserve capacity. A frequency response link is added to the power control, so that the unit can output power to realize inertia and frequency support when the system frequency fluctuates. The simulation results show that the proposed control strategy can improve the system inertia and primary frequency modulation capability in the full wind speed operating domain under the load mutation condition, and improve the frequency stability of the system after the wind turbine is connected to the grid.

Analysis and Improvement of the AC-Voltage Control of GFM MMC to Improve the Voltage Stability of AC/dc Hybrid Power grid

Analysis and Improvement of the AC-Voltage Control of GFM MM...

引用

IEEE International Symposium on Power Electronics for Distributed Generation Systems (PEDG)

The grid-forming control is regarded as an effective solution for grid-tied converters to operate under weak grid conditions. Currently, most of the grid-forming control strategies are designed for 2-level voltage source converters. The Power loop-AC voltage loop-AC current loop control is usually adopted in these strategies. This control structure highly relies on the AC side filter capacitor. However, in high-voltage situations, the modular multilevel converter, which has no AC side filter capacitor, is commonly adopted. The integral effect of the filter capacitor in the original control path is replaced by the differential effect of the grid impedance, which worsens the performance of AC voltage control. To solve this problem, the steady-state model of MMC using grid-forming control is established. Based on this model, two improved AC-voltage control strategies are proposed in this paper. simulation results in PSCAD/EMTdc show that the proposed control realizes desired dynamic control of the dc voltage.

The safe operation of smart substation is an important guarantee to ensure the stability of power supply. Aiming at the problems of substation data anomaly identification caused by large amount of substation data, complex data and high dimension, an smart substation anomaly data detection method based on K-means-SVM is proposed in this paper. Firstly, the unlabeled substation data is transformed into labeled data by K-means method, and then the unsupervised classification results provided by K-means are used as the training data of SVM. After SVM training, use the trained plane to test the two types of data obtained by K-means clustering, use the accurate data predicted by SVM to retrain the SVM segmentation plane, and iteratively update the SVM segmentation plane according to this method until the error number of SVM prediction data is not changed. This method can effectively improve the accuracy and efficiency of substation abnormal data identification, so as to improve the operation and maintenance safety and equipment maintenance ability. © 2023 SPIE.

At present, offshore wind power has become an important development direction for wind power generation. Offshore wind farms often use high-voltage direct current transmission technology with modular multi-level voltage source converters (MMC-HVdc) to transmit electricity to the grid. However, the fault response characteristics of offshore wind farms through the MMC-HVdc transmission system are different from those through AC transmission way. Therefore, it is significant that studying the fault ride through (FRT) technology of offshore wind farms through the MMC-HVdc grid connection system for practical engineering. An electromagnetic transient simulation model for an offshore wind farm composed of a direct drive permanent magnet synchronous generator (D-PMSG) connected to the grid is established through MMC-HVdc transmission technology. The mechanism and suppression strategy of overvoltage generation in the transmission network are provided during the fault clearance and recovery phase of the offshore wind farm HVdc transmission system under AC asymmetric faults. A two-stage improved control strategy for MMC-HVdc offshore converter station in response to asymmetric faults has been proposed, which is beneficial for the joint system to quickly recover from the post fault system voltage and suppress the overvoltage risk during the fault clearing phase. Finally, the proposed strategy is validated based on a domestic ± 500kV project in China, demonstrating its effectiveness.

The power synchronization based vector control is proposed with the power synchronization controller (PSC) replacing the conventional phase locked loop (PLL) recently. It is reported that the power synchronization unit can have comparable performance of the conventional PLL based vector control. However, the steady state analysis of the PSC control dq frame orientation and the corresponding steady equilibrium points are not discussed. Worse more, fault ride through of the PSC based vector control is not addressed in the related literatures. First, the measurements error on the performance on PSC based vector control is analyzed and the enhanced PSC based vector control is proposed to further reduce the control complexity. Based on the enhanced PSC based vector control, the equilibrium points and the dq frame orientation of PSC based vector control and its comparison with PLL based one are analyzed in the normal operation. After that, the fault ride through strategy is proposed with consideration of equilibrium point. Finally, simulations using PSC based vector control for voltage source converter based high voltage dc transmission station (VSC-HVdc) are carried out to verify the analysis.

With the depletion of global fossil energy and the worsening of global environmental problems, the development and utilization of renewable clean energy has become an important direction in the world's energy technological change. Hydrogen energy, as a highly clean renewable energy, has become a research hotspot in the world. In this paper, a typical offshore energy system model is proposed. Firstly, according to the thermodynamic phenomena and electrochemical dynamic characteristics of the alkaline electrolyzer, the electromagnetic transient model of hydrogen production unit is established. Then, a grid-connected control scheme based on the direct current of the electrolyzer is proposed to connect the offshore wind farm with the hydrogen production system. Finally, a complete model is built on PSCAD and the electromagnetic transient simulation analysis is carried out. The results show that the system can provide stable and reasonable dc current to hydrogen production system through 60 mw wind farm, which verifies the correctness and effectiveness of the model.
