A close association has been identified between the theoretical calculation of geomagnetically
induced currents (GICs) in a large network, practical measurements of GICs, the results of …

Accurate loss minimization is the critical component for efficient electrical distribution power
flow. The contribution of this work presents loss minimization in power distribution system …

Extreme space weather due to coronal mass ejections has the potential to cause considerable
disruption to the global economy by damaging the transformers required to operate …

Owing to the ever-present solar wind, our vast solar system is full of plasmas. The turbulent
solar wind, together with sporadic solar eruptions, introduces various space plasma …

Abstract Space weather phenomena have been studied in detail in the peer‐reviewed
scientific literature. However, there has arguably been scant analysis of the potential …

Records of faults occurring on the South African power transmission system over a 16-year
period have been collected. Over 12,000 faults were analysed to find statistical relationships …

Electrification programmes and projects are usually planned and evaluated on the basis of
their economic (financial) and socio-economic performance. It is not usually recognised that …

Conditions on feeders with dispersed generation vary between voltage drop when there is
no generation, and voltage rise when the generation exceeds the load. The utility is …
