Addressing the issue of renewable energy integration caused by large-scale wind power grid connection, a novel electric power system distributed robust joint chance-constrained (DRJCC) optimization dispatch model incorporating captive power plants with virtual energy storage (VES), wind, thermal, and hydropower units is proposed. Initially, considering that high-energy-consuming enterprises' self-provided power plants (SPPPs) can accept the unified dispatch of the public grid, three operational modes for the SPPPs as VES participating in the main grid interaction and their call costs are presented, and a two-stage stochastic optimization model for the new power system including VES is constructed. Subsequently, a data-driven DRJCC approach is utilized to address the uncertainty in wind output, constructing a fuzzy set of probability distributions for uncertain variables based on the Wasserstein distance, and expanding the original stochastic optimization model to a W-DRJCC optimization model. Further, by applying strong duality theory, Bonferroni inequality, and Conditional Value-at-Risk (CVaR) approximation, the proposed distributed robust model is transformed into a mixed-integer linear programming problem for solution. Finally, case analyses on an improved RTS-24 power system demonstrate that the proposed method can balance economic efficiency and robustness, offering significant insights for the construction of operational modes for enterprises' SPPPs to participate in grid interaction.

Light gas protection only operates when gas within the transformer collection chamber reaches threshold volume. Such criterion failed to reflect transformer conditions accurately due to the lack of understanding for defect developing process and corresponding gas generation- convergence pattern, which has led to lower protection reliability and has caused several transformer explosions. To address current problem, an experimental tank with structure resembling that of a power transformer is set up, inside which the needle-plate oil-pressboard breakdown model is planted. Experimental results indicate that throughout fault development, voltage drops became more frequent until arcing occurs, so is HFCT signal;meanwhile gas generation rate increases through slight partial discharge, spark discharge and arcing stage, the collected gas volume corresponds with patterns above. The purpose of this study is to clarify the defect developing process and the gas generation-convergence pattern for oil-immersed transformer internal fault in guidance for a more reliable protection method. © 2021 IEEE.

With the wide application of power semiconductor devices in severe working conditions, the reliability and lifetime estimation of power semiconductor devices have become the research hotspot. Power cycling test is a significant method to study the reliability issues. This paper first analyzes the existing methods and then proposes a new power cycling method which considers not only realistic electrical conditions but also the thermal stress from different regions. Firstly, rainflow algorithm is used to extract the temperature cycles with large amplitude. Next, the junction temperature cycles and case temperature cycles are matched using integer programming algorithm and modified by means of equivalent substitution. At the same time, a method to control the case temperature and the junction temperature simultaneously is proposed. Afterwards, modified rainflow reconstruction algorithm is used to combine these matched cycles to temperature arrays. Finally, test load profile is formed. An electric vehicle motor drive system based on the Worldwide Harmonized Light Vehicle Test Procedure mission profile is used to verify the proposed method. This method can simultaneously stress the bonding wire and the solder layer, which provides a new way to access the reliability of power devices in real application. © 2021 IEEE.

The high proportion of renewable energy into the power grid, say, the large-scale wind power generation connected to the power grid, is the key approach to achieve the clean and low-carbon energy transition. Under the premise of ensuring power grid's safe and stable operation, it is necessary to study the influence of wind power capacity expansion on the transient angle stability (TAS). Aiming at several typical dominant modes in Qinghai power system, which holds many new energy resources, the sensitivity of wind power capacity expansion in different locations to the TAS, as well as its key influence factors and feasible explanations, are explored. It may lay the foundation of the location optimization of wind power capacity expansion. © 2020 IEEE.

The national carbon market is the major market mechanism supporting China's “30•60” target. This market involves natural sciences, such as energy technology and climate science, and social sciences, such as politics and economics related to energy economy, policy, and human behavior. This makes the carbon market a typical cyber-physical-social system in energy (CPSSE). This paper focuses on modeling objective physical parameters associated with market participants. The paper proposes a model and value assignment method for unit-level heterogeneous parameters and constructs a unit-level dataset of national carbon market participants. The influences of the heterogeneous levels of different parameters on the micro supply-demand balance are then evaluated. The study details the quantitative influences of the proportion of units without key parameter measurements and the shape of the distribution of the units' coal consumption rates. This study establishes a unit-level model and parameter foundation for conducting a national carbon market hybrid simulation.

With the large-scale access of new energy sources, the operation mode and the uncertainty factors of the power grid increase, meanwhile the short-term power shock has an increasing impact, which exacerbates the complexity of the system frequency response characteristics and the difference in space-time distribution. Based on the analysis of principles and adaptability of emergency control and correction control, this paper comprehensively considers the operation mode and new energy access, and proposes a centralized control decision-making method based on model and trajectory driving from the perspective of global frequency control. The method also considers the continuously adjustable control resources and low voltage ride through of new energy. Finally, the practicality of the proposed method is verified based on the actual power grid simulation.

The rapid development of UHVDC, new energy and power market enhances significantly the uncertainty of power grid. The control strategy of stability control system calculated offline cannot cover the complex and changeable power grid operation situation. A hierarchical closed-loop stability control system is proposed to meet the stability control requirements under multiple and cascading faults, including dispatching center station, coordination control master station and regional control master station The dispatching center integrates natural disaster information to generate high-risk faults and searches online control strategy based on controllable resources acquired by coordination control master station. Coordination control master station stores control strategy of high-risk faults, identify high-risk faults in different places, and issue the control strategy. Regional control master station is responsible for the implementation of high-risk faults control strategy. The analysis results demonstrate that the system can improve the security defense level of power grid. The proposed method is proved to be fast and effective through the analysis of a practical power grid example.

As a new technology, 5G technology has lower cost than optical fiber and comparable transmission speed and carrying capacity, which can improve the performance of distribution network communication system. At the same time, differential protection based on two terminal data cooperation has a new life. However, 5G signal has delay jitter, and the transmission delay of channel may change, which increases the difficulty of synchronization and affects the reliability of differential protection. Therefore, this paper proposes an improved protection method based on dynamic time bending distance, introduces floating threshold as braking value, improves the reliability of protection, and has good adaptability to delay jitter and asynchronous error, which has certain engineering significance. © 2022, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.

In the low-resistance grounding system with inverter interfaced distributed generator (IIDG), the IIDG widely uses the neutral point through the low-resistance grounding method. But the IIDG, which adopts the neutral point grounding through a low resistance, will affect the fault characteristics of the original low-resistance grounding system. This paper uses the symmetrical component method to establish a single-phase grounding fault model for the distribution network where the neutral points of the IIDG and the main network are grounded with low resistance. The fault current, the zero-sequence current, and the three-phase current of the line are analyzed when the upstream line of the grid connection point, the downstream line of the grid connection point, and the adjacent feeder fail. Finally, a simulation model was built using Matlab/Simulink to verify the correctness of the analysis. The conclusion provides a basis for the protection configuration of the distribution network in which the neutral points of the IIDG and the main network are grounded with low resistance. © 2021 IEEE.
