Transactive Energy (TE) is an evolving concept that combines information and energy in order to enable highly coordinated energetic transactions. Different sources define transactive energy in different ways. The GridWise Architecture Council (GWAC) defines TE as 'A system of economic and control mechanisms that allows the dynamic balance of supply and demand across the entire electrical infrastructure using value as a key operational parameter' . This definition is general enough to holistically cover all TE related issues. In a top-down approach, a question asked is if power electronics (PE) is ready to face the challenges posed by TE. Other questions are: What will be the role of PE in the future TE systems? What type of PE devices will play a key role? © 2014 IEEE.
