In the case of large-scale power loss fault in the operation of UHV AC-DC hybrid power grid, it is impossible to adjust the grid correction control problem by the unit output adjustment. Fully utilize the adjustable capacity of the load control to achieve safety correction control to meet the load control aid decision-making requirements of existing dispatching system. According to the characteristics of the dispatching system in accordance with the sub-regional load as the target of unified implementation of load control, this paper proposes a safety correction optimized aid decision-making calculation method based on sub-regional load control, with the sub-regional load as the control object and the minimum sub-regional load as the target. Consider the system power flow constraint, the sub-regional controllable load constraint and the key monitoring section safety constraints, the continuous power flow method and the line planning method are combined to solve the problem. The proposed method has the characteristics of simple model, easy solution and good convergence. It shows the effectiveness of the proposed method in the actual power grid. 1

Real-time assessment of the risk of continuous commutation failure of the thyristor-based phase-controlled commutation direct current transmission system (LCC-HVDC) and timely preventive control measures are of great significance to ensure the safe and stable operation of the large power grid. This paper proposes a method for evaluating effective dynamic reactive power reserve of generators to deal with DC continuous commutation failure. The maximum reactive power increment of the generator corresponding to the secondary drop of the converter bus voltage is defined as the effective dynamic reactive power reserve. The effective dynamic reactive power reserve at the critical point is called the maximum effective dynamic reactive power reserve. When the system dynamic reactive power reserve is less than the reserve capacity threshold, a two-stage preventive control measure searching method is adopted. First, increase the terminal voltage of the generator and the static reactive power compensation. If the requirements are still not met, the start-up unit measures will be adopted. An example of an actual power grid verifies the effectiveness of the method. © 2021 IEEE.

The battery energy storage technology can be flexibly configured and has excellent comprehensive characteristics. In addition to considering the reliability of the battery energy storage power station when it is connected to the grid, the reliability of the energy storage power station itself should also be considered. The reliability model based on Copula theory was established for battery module, and the reliability of energy storage module was analyzed according to the basic structure of energy storage modules. In this paper, the example analysis is based on the existing simulation model of energy storage module. Then the reliability of energy storage module in the next 20 years is predicted considering the different correlations between battery clusters. © 2022 IEEE.

With the increase in power system load, the number of switch cabinets increases rapidly, and the accidents caused by DC operating circuits become more and more obvious. Abnormal detection has become an important part of the DC operating circuit. Abnormal data, mainly voltage measurement, often contain important information. Finding and analyzing these abnormal data can give early warning for circuit failure or failure. However, abnormal data is often difficult to obtain and lacks marks, that is, the problem of sample imbalance and unsupervised problems, resulting in abnormal detection methods that can not meet the increasing accuracy and efficiency requirements. Generative adversarial network (GAN) is an unsupervised deep learning model, which has been successfully applied to unsupervised time series anomaly detection. However, GAN has technical difficulties in the anomaly detection process, and there is still room for optimization in accuracy. In this paper, the unsupervised time series anomaly detection method based on GAN is studied, and an anomaly detection method of a DC operating circuit combined with LSTM and GAN is designed. © Published under licence by IOP Publishing Ltd.

Safety is an important factor restricting the cascade utilization of lithium-ion batteries (LIBs). In this paper, the safety characteristics of fresh and retired lithium iron phosphate batteries are investigated by means of a heating-triggered thermal runaway (TR). The results show that under the heating condition of 200 W, the internal short circuit (ISC) can directly cause the TR of a new battery and lead to an explosion with an overpressure of 98.9 kPa. However, there is still a buffer time of 13.1-22.3 min between the ISC and TR for the retired battery with states of health (SOHs) of 80% - 60%, and the retired battery cannot explode. The large-scale ISC onset time, TR onset time, and TR onset temperature of the 70% SOH battery are 27.4 min, 40.5 min, and 179.9 °C, respectively, which are the smallest among retired batteries, indicating that the 70% SOH battery may be more likely to trigger TR. The findings can provide guidance for the safe application of retired batteries. © Published under licence by IOP Publishing Ltd.

New energy has been vigorously promoted for its advantages such as cleanliness, large reserves and renewability. Recently, power-to-gas (P2G) technology has provided a new idea for energy conversion, which helps to improve energy efficiency. In view of the current high penetration rate of photovoltaics, the impact of three measures with regard to energy conversion, energy storage configuration and demandside response on the economics of the microgrid and the optimal scheduling of the microgrid are explored. Firstly, a microgrid scheduling model with P2G device is built;Secondly, a bi-level planning model for the economic cost of the microgrid scheduling is presented. The upper layer will be based on absolutely accommodation of photovoltaics as the prerequisite to conFigure the optimal energy storage capacity;Then lower layer performs optimized scheduling under the upper model to ensure the economy of the microgrid. Finally, a comparison example is used to analyze the optimal energy storage capacity in different scenarios and an optimized scheduling scheme is given. © 2020 IEEE.

The HVDC transmission schedule for clean energy seldom considers the demand of receiving grid. With the expansion of clean energy scale, it brings great pressure to the receiving grid for safe and stable operation. For this reason, a generation and transmission scheduling model of inter-regional HVDC tie-line system considering conditional section is proposed. A step power adjustment model for the HVDC tie-line operation optimization is developed with consideration given to various constraints on tie-line power, which not only give full play to the characteristics of HVDC tie-line that can be flexibly adjusted, but also avoid the frequent conversion of HVDC converter equipment, making the HVDC tie-line schedule more executable. The joint operation model of cascaded hydropower plants in sending grid is established to meet the operational constraints such as the restricted operating zones of hydropower units, and to ensure the priority of clean hydropower resources and the practicability of the hydropower schedule. The model of conditional control section is established, which can effectively deal with the problem of the coupling between the power limits of section and the number of running units, so as to ensure the safe and stable operation of related sections. Based on the actual data of a cross-regional interconnected power grid, the validity of the model is verified, which can promote the accommodation of clean energy across a wide range of regions, reduce the supply cost of large power system, and alleviate the pressure of safe and stable operation at the receiving system.

Capacitance current has significant effect on long-distance fault of high-voltage transmission line, and the current single-ended quantity location algorithm can hardly eliminate the effect of capacitance current under the power frequency. To reduce capacitance current’s effect on location algorithm, this paper builds metallic grounding fault model based on RLC type circuit, takes fault location as the unknown variable, builds a mathematical location model within time domain applicable for taking account of capacitance current, and obtains the quadratic equation with one unknown for fault location. Then it substitutes the two independent variables for the linear term and quadratic term, solves independent variables through linear equation, and proves the solution exists and is unique. Then under analysis on the same difference error, it compares magnitude of error generated during calculation of the two independent variables, it corrects difference error first, and inversely solves fault location by selecting the numerically disturbed smaller independent variable. Simulation results indicate the algorithm can accurately take account of effect of capacitance current under different metallic fault conditions, and solve fault location in a stable and accurate manner.

As the sampling interruption is the heartbeat of merging unit, its stability is directly related to the accuracy and discreteness of the output SV packets of merging unit. To prevent the output error from merging unit when its sampling interruption is abnormal, this paper proposes crystal frequency monitoring technology, sampling interruption monitoring technology and SV packets timing monitoring technology, forming the prevention and control system of sampling interruption exception of merging unit. The merging unit developed by above technology has the function of early warning and processing for the occasional sampling interruption exception, which improves the reliability of intelligent substation operation.
