As renewables increase, so will the need for a supergrid

The rapid rise of variable renewable generation is increasingly challenging both market and grid operators as the real-time balancing of load and generation becomes more difficult. Demand response, pumped storage and more flexible generation with fast ramping features are among the solutions. Another solution, however, is more transmission and larger integrated grids which allow for […]

Supraharmonics in transmission and distribution networks

Standards for harmonics in power networks (transmission and distribution) usually deal with the range below 2 kHz, as most of the harmonics due to waveform distortion fall into this range. Harmonics or disturbances in the range above 2 kHz are becoming noticeable in networks due to the introduction of inverter based distributed generators, and are […]

Dealing with inrush currents in distribution transformers

Among the subtleties associated with distribution switchgear configuration, inrush current is a necessary evil which must be taken into consideration. It is the source of much frustration for field operators and SCADA control teams; when issuing a close command on an open breaker results in an immediate trip. Was it genuine fault? Is it risky […]
