Although the traditional stability theory based on synchronous motor characteristics has been improved and validated for over a century, it has limitations in dealing with the rapid changes brought by renewable energy sources and high-power electronic devices in modern power systems. Research into supporting technologies has become an indispensable element in the evolution of the new power system,...Show More
Although there has been a lot of research for the traditional power system, and got a lot of effective stability analysis methods and instability mechanism because of the importance of power system stability in the power system, with energy change and power electronics development, traditional stability theory which instability identification is for a single inverter grid connection is not readily...Show More
With the shift from traditional thermal power generation to renewable energy generation modes, the power equipment used in traditional generation cannot be directly applied to renewable energy systems. Currently, power electronic converters are commonly controlled using GFL (Grid-Following) converters and GFM (Grid-Forming) converters. However, the integration of renewable energy increases the pot...Show More
With the increasing proportion of renewable energy and power electronic equipment in power systems, the problems of broadband resonance and harmonic stability caused by the dynamic interaction between grid-connected inverters and the power grid become increasingly prominent. The dq impedance method based on a small signal model in the frequency domain in a synchronous rotating coordinate system is...Show More
This paper considers the combination of distribution-side distributed small battery energy storage clusters and charging and swapping station aggregates as the virtual control unit (VCU). This paper combines with the existence of the VCU operated by intermediaries in the operation of the actual power system, establishes the optimal model of self-scheduling of the VCU in the day-ahead stage. The mo...Show More
Developing and integrating advanced image sensors with novel algorithms in camera systems are prevalent with the increasing demand for computational photography and imaging on mobile platforms. However, the lack of high-quality data for research and the rare opportunity for an in-depth exchange of views from industry and academia constrain the development of mobile intelligent photography and imag...Show More
