Large-scale grid-connection of wind power has a profound impact on the characteristics of power grids. To study the mechanism of the influence of voltage sudden changes on the transient response characteristics of double-fed wind fields is the basis of ensuring the safe and stable operation of power grids. In this paper, the expression of rotor current under symmetrical voltage sudden changes is derived, and the related factors affecting the transient response characteristics of rotor current are analyzed. Then, a detailed DFIG model is built in PSCAD, and a variety of scenarios are simulated to verify the accuracy of the proposed doubly-fed fan's transient response characteristics under symmetrical voltage sudden changes. © 2023 IEEE.

With the increasing penetration of new energy, the problem of static voltage stability of power grid has become increasingly prominent, and there is an urgent need for a static voltage stability analysis method to simultaneously evaluate the new energy stations and load buses in a region. To solve this problem, this paper proposes a static voltage stability index based on the voltage stability criterion, which is used to judge the voltage stability of new energy station buses and load buses in the regional network. Firstly, based on the Thevenin equivalence method, the power network with a high proportion of new energy is equivalent to a single machine single load system;Secondly, the analytical static voltage stability index is derived based on the voltage stability criterion;Then the mechanism of this index is compared with L index from the analytical formula, and the reasons for the error of L index in the case of heavy load and large new energy generation are described;Finally, the validity and accuracy of the proposed index in judging the static voltage stability of new energy stations and load buses are verified based on the modified IEEE 3-unit 9-bus example with new energy stations. © 2023 IEEE.

power conversion system is the key equipment to realize two-way energy transfer between energy storage battery and AC power grid. This paper introduces a design and control method of power conversion system for emergency power supply. The power conversion system can select grid connected operation or independent on load operation to meet the multi scenario application requirements of emergency power supply site. During grid connected operation, the input power is controlled by controlling the input current, and then the output voltage at the DC side is controlled. During independent load operation, the load voltage and frequency are controlled by controlling the output voltage amplitude and frequency of the converter. The proposed constant voltage current limiting control strategy can maintain the DC bus voltage near the reference value and improve the reliability of battery charge and discharge. © 2022 IEEE.

The popularization and promotion of smart home appliances and electric vehicles represents a challenge as well as an opportunity for distribution system operators. On the one hand, these new loads will significantly increase the operating burden of the distribution area;on the other hand, the controllability of these new devices also makes it possible to meet various technical and commercial purposes through flexible solutions such as incentive demand response. Based on the massive operation data collected from electricity meters, low-voltage fault indicators, leakage protection units and other devices in the distribution station area, a fuzzy comprehensive evaluation method is proposed to manage the operation status of low-voltage circuit in distribution station area. Then the evaluation results are applied to the incentive demand response, which realizes the comprehensive management of three-phase unbalance and under-voltage of low-voltage circuit in distribution station area through reducing load. The simulation results show that the proposed strategy can quantitatively evaluate the operation status of the distribution station area, and improve the load distribution and voltage level of distribution station area significantly through utilizing incentive demand response. © 2022, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.

The domestic distribution network is mainly non-effectively grounded system, single-phase grounding fault accounts for more than 80% of the total number of faults, the fault characteristics are not obvious and easy to be affected by noise signals, at the same time, the polarity of zero sequence voltage and current transformer is unknown or reverse connection often occurs, which makes the local fault identification and line selection more difficult, and directly affects the fault response speed and disposal efficiency. In this paper, an improved single-phase to ground fault line selection method based on transient energy is proposed. By using the energy matching degree of transient zero mode current in each interval and the polarity relationship between transient zero mode current and steady-state zero sequence current in this interval, the existing fault line selection methods are easy to be affected by the polarity of external mutual inductors, and the polarity of mutual inductors can’t be checked online in the fault process. The physical concept of the method is clear, and the criterion threshold is not affected by the grounding mode and fault location of the system. RTDS simulation experiment and field engineering application verify the effectiveness and universality of the proposed fault line selection method. © 2022, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.

With a growing share of renewable energy being incorporated into microgrids through power electronic converters, isolated microgrids are at higher risk of losing transient stability when exposed to significant disturbances, primarily due to the reduced inertia and increased nonlinearity inherent in power converters. This paper introduces a novel control strategy aimed at enhancing transient stability for the grid-forming converter within the islanded AC microgrid, utilizing model prediction techniques. By adjusting the output voltage of the grid-forming converter with the additional term produced by model prediction, the balance between the system's equivalent input and output torques can be accelerated. The proposed strategy's effectiveness and superiority are validated through simulation using MATLAB/Simulink. © 2024 IEEE.

The performance of conventional protections is serious challenged by different fault characteristics of wind turbine, compared to the synchronous generators. The existing studies can only illustrate the applicability of protections to the renewable energy transmission system through qualitative analysis or extensive simulations. This paper proposes a quantitative evaluation method for distance protection applicability in wind power transmission system. Firstly, by deriving the fault current of doubly-fed induction generators, the Fourier algorithm error of the fundamental frequency current under the influence of frequency deviation phenomenon is calculated. Secondly, based on the analysis of the measured impedance error caused by the Fourier algorithm error, the action accuracy of the distance protection under different operation states and fault conditions are obtained. In particular, the protection applicability under different wind power ratios is evaluated for the wind power transmission system bundled with synchronous generators. Finally, a real time simulation model of wind power transmission system is built based on RTDS platform, and extensive simulation cases are carried out to verify the validity of the proposed method. © 2023 IEEE.

With the increasing penetration of renewable energy, how to maximize the acceptance of renewable energy on the basis of satisfying the economy security and reliability of the power system is an urgent problem to be solved. In this area, mathematical optimization methods such as robust optimization and stochastic optimization are generally used to construct models based on different uncertainty descriptions. Previous studies have shown that robust optimization has high computational efficiency but conservative results, while stochastic optimization has low computational efficiency but accurate results. Therefore, different studies will choose suitable methods based on the characteristics of the models to be constructed. However, existing studies have not thoroughly discussed whether there is a connection between the two methods. This paper first proposes an economic dispatch model based on scenario considering the admissible region of net load, and introduces a new affine strategy to transform this model into a deterministic form. Secondly, based on further exploration of the characteristics of economic dispatch models based on scenario/interval, the paper concludes that the two models are common when they are sufficiently precise. Finally, the correctness of the conclusion is verified on the IEEE-RTS system. © 2023 IEEE.

For the current traditional power grid dispatching and control system, the display effect of configuration software interface is ordinary, and the configuration interface is cumbersome. This paper presents a state animation technology of configuration software for power grid and control system. By defining multiple states in the configuration editor, modifying component attributes in different states, setting state switching animation types, associating the animation change functions of component attribute values in different states, saving in CIM/G format, and then opening the corresponding files through the browser, the component attributes can be dynamically transformed between attribute values in different states, Batch modification and animation of component attributes are realized, which enriches the display effect of the interface and improves the friendliness of human-computer interaction. © state grid Electric power Research Institute 2023.
