As solar, wind, and other renewable energy methods become more prevalent, micro- and offgrid installations will suffer from frequency instability and high risk of blackouts. Changes in wind and/or solar energy production have an impact on the frequency a grid can deliver. Also, if the exact amount of electricity being used is not matched by generation,...

Frequency deviations are caused by imbalances in load in generation and lead to high risk of load shedding or grid black outs. The higher the rate of renewable energy production is of the energy mix, the more of a problem the variation of frequency can become.

Short-term UPS solutions are essential in industries where voltage dips and micro-interruptions can cause severe issues in manufacturing processes. This is especially the case with for example semiconductor manufacturing, the pharmaceutical industry, or even bottling plants. A single disturbance event can result in millions of euros in losses due to...

A popular use case for gensets is back-up power, which means that they need to start reliably and come online quickly when the need for power arises. Most often gensets are started with lead-acid batteries - a technology not known for its reliability. Skeleton Technologies' SkelStart Engine Start Module provides a solution: reliable, high-power solution...

Random high load variations can cause severe issues for Variable Speed Generators, or VSGs. These machines are used in renewable power generation (the application of interest in this blog post), but also in marine and shipbuilding, oil & gas industry, telecommunications, stand-by power, and a large number of other industries and applications.

Variable Speed Drives (VSDs) are important for various production processes, because they are used to operate the electrical motors powering those processes. However, poor power quality can impact the production processes negatively, leading to machinery and production shutdowns and production loss. In some cases cleaning up the production lines and...
