Special Issue Information

Dear Colleagues,

Building an energy internet situational awareness system with comprehensive coverage and precise feedback is an important development trend in which electrical equipment state measurement and intelligent calculation play an important role. With the increasing integration of clean energy into the grid, greater challenges are introduced to the condition monitoring of electrical equipment, and accurate measurement of electrical equipment parameters and rapid processing of measurement data through intelligent calculation methods are crucial. This also has broad application prospects in aerospace, ocean, industry, and other fields.

This Special Issue aims to present and disseminate the most recent advances related to the theory, design, modeling, measurement, application, and condition monitoring of all types of state measurement and intelligent calculation.

With the popularization of power electronic equipment, the problem of harmonic pollution has become more and more prominent, posing a serious threat to the safe operation of power systems. In order to improve the stability and efficiency of the power system, the broadband measurement of harmonics has become a key direction of research. In this paper, a novel broadband harmonic measurement method is proposed, which combines the electric field sensing technique and the TCW add-window discrete Fourier transform technique. The amplification gain coefficient deviation of the measurement system is less than 3 dB in both steady-state and transient excitation signal test experiments. The measurement system can maintain a stable and continuous output in a wide frequency band within the range of MHz, which can effectively detect the harmonic components and provide an effective technical means for the monitoring of harmonics in the power system.

To address the problems of “difficult to consume” renewable energy and the randomness of power output, we propose the CHP unit joint-operation model with power to gas (P2G) and carbon capture system (CCS) technologies and analyze the operation cost, carbon emission, and “electric-heat [...] Read more.
To address the problems of “difficult to consume” renewable energy and the randomness of power output, we propose the CHP unit joint-operation model with power to gas (P2G) and carbon capture system (CCS) technologies and analyze the operation cost, carbon emission, and “electric-heat coupling” characteristics of this model. A dispatch optimization model is constructed based on the information-gap decision theory under the strategy to further consider the interval uncertainty of renewable energy unit output and load forecast. The optimized-dispatching model effectively solves the fate of renewable unit output and electric-thermal load and provides dispatching strategies for decision-makers to balance risk and capital management.
