In the engineering survey in currentelectric power, several kinds of coordinate system and elevation in common use and their mutual matrixing relation are introduced. 本文介绍当前电力工程测量中常用的几种坐标系和高程系及其相互换算关系。 A dynamic game model based on different decision rules is establis...
Power electronics and communication electronics are both based on electromagnetic theory, but they are usually regarded as two distinct subfields in electrical engineering. In fact, however, electric power is the most common matter-based carrier of messages; thus, power electronics and communications can...
The energy generated from the wind has proven to be of interest for several reasons鈥攚ind is available, it is a cheap, and virtually inexhaustible source of energy. In this relation in the last years, many wind power stations were built all around the country. They are being located in ...
Electrification plays a crucial role in deep decarbonization. However, electrification and power infrastructure can cause mutual challenges. We use nationwide power outage and electric vehicle adoption data in China to provide empirical evidence on how power infrastructure failures can deter electrification....

Economic development relies on access to electrical energy, which is crucial for society’s growth. However, power shortages are challenging due to non-renewable energy depletion, unregulated use, and a lack of new energy sources. Ethiopia’s Debre Marko

and fast simulation. It is notable that most of these studies relied on the direct relation between current and voltage, and focused on the small-signal stability. However, we would like to emphasize that the essence of oscillations in a power system is power conversion. A direct relation ...
The magnetic permeability and loss properties of Ni-Zn ferrites can be tailored by making strategic changes in crystallography, morphology and microstructure of the material. The relation between the complex relative permeability and frequency is termed as permeability dispersion. The frequency dependent ...
To overcome these difficulties, we have applied several well-known popular metaheuristic algorithms (Water Cycle Algorithm (WCA), Artificial Electric Field Algorithm (AEFA), Teaching Learning Based Optimization Algorithm (TLBOA), Grey Wolf Optimizer Algorithm (GWOA), Sparrow Search Algorithm (SSA), ...
