The world of electrical energy provision is transforming at a rapid pace. The convention of centralised generation, transmission and distribution is fast changing with the ever-increasing adoption of renewable generation technologies, battery energy storage and new electric applications, such as electric transport.

Until now the generation of electrical power has been managed to meet the demand, whatever it may be. A shortage of
generation capacity results in load shedding, which is a blunt tool to manage demand. As the increasing adoption of renewable energy sources increases the unpredictability of generation, new ways need to be implemented to manage demand to match the available electric power generation.
