Modern electrical networks continue to grow in complexity due to significant investments in Distributed Energy Resources (DER) like wind and solar which contribute larger portion of the energy mix. Additionally, large data centers, electric vehicles charging and high-speed railways are growing as energy consumers. This diversity of both sources and demand presents challenges for producers and consumers of electricity to maintain grid stability along with network power quality.

Voldemort is the primary villain in the famous Harry Potter series by J K Rowling. In the books, his rise to power is marked by atrocities so horrifying that few wizards dare to even speak his name. He is also a stark example of the havoc evil can wreak, if allowed to grow unabated in something that is inherently good and powerful. Power quality works somewhat in a similar manner.
