A study of the transient processes in the physical model of the electric power systems with predominant part of the renewable energy sources [PDF]
E3S Web of Conferences, 2021 The renewable energy take part in the most of the electric power systems in the modern world. The part of this type of energy in the global electric power system, as well as in the local scale, increases with the setting the stricter requirements for ...

Active Currents, Power Factor, and Apparent Power for Practical Power Delivery Systems
IEEE Access, 2020 Concepts of apparent power and power factor as measures of a system's power delivery capability are over a century old but have not been defined in one general, rigorous and acceptable way.
