Power transformers are static devices transferring electrical energy between two circuits with separate systems of alternating voltages, by means of electromagnetic induction. They …
Power systems need to incorporate rising shares of intermittent renewables. The penetration levels of renewable energy sources, inverter-based resources and inverter-based loads …
In modern power networks with high shares of renewable energy sources, and a mixture of alternating (AC) and direct current (DC) technology in different sections of the network, …
Renewable energy is key to stopping climate change, however, the intermittent nature of most forms of renewable energy generation poses a challenge. Energy storage is therefore a …
Phasor measurement units (PMUs) provide time synchronized measurements of phase angles of voltages or currents. These synchrophasors are used in electricity grids to support …
Lightning is important for all scientists and engineers involved with electric installations. It is gaining further relevance since climate warming is causing an increase in …
The growing share of renewable energies, as well as the rising demand for electricity for transport and heating, are increasing the importance of power converters and the …
To optimise the efficiency of electric drives it is necessary to consider the components; the power electronic converter, the electric machine and the gearbox, together. Integrated …
Lightning is important for all scientists and engineers involved with electric installations. It is gaining further relevance since climate warming is causing an increase in …
Power electronics converters are devices that change parameters of electric power, such as voltage and frequency, as well as between AC and DC. They are essential parts of both …
