Power System Solutions

Both the utility and the business end of the power grid are increasingly employing power electronic energy conversion to increase efficiency. The desire to “decarbonize” power generation has led to the ongoing shift towards renewable distributed energy resources (wind, solar, storage, etc.) coupled to the grid through power electronics. The result is more harmonics and a weaker system. Businesses pursuing increased efficiency and productivity are increasingly relying on harmonic producing power electronic converters and loads that vary energy consumption rapidly.

The result of a weakening grid and an increase in harmonic producing, rapidly varying loads is a reduction in power quality and consequentially more negative impacts on the system and the components, such as transformers, motors, and capacitors.
