ransactive 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 " [1]. 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?
Several discussions about the role and challenges of
PE are under way amongst the scientific community. To
determine whether centralized or decentralized supervisory
control [2], distinct technologies (IoT, Blockchain)
and infrastructures can be addressed (Advanced

Microgrids, Peer-to-Peer (P2P) Energy Trading) [3]. This
paper provides insight into two key PE devices that provide
essential bridging functions in the TE paradigm (the
Residential Energy Router and the Smart Transformer),
in relation to the TE nodes established across the entire
electrical power system value chain.
Transactive Energy and
the Electrical Power System
Over the last decades, the energy market has evolved
from a traditional monopoly framework into a distributed
market mostly due to the high penetration of distributed
energy resources (DERs), essentially in the lower base of
the pyramid. This rising integration of smaller production
units are allowing traditional consumers to act as producers
(the so-called prosumers) allowing them to share
their surplus with other prosumers or negotiate directly
with the energy provider (Transmission System Operators
(TSO) or Energy Service Companies). TE can be
applied throughout the entire value chain in the electrical
power system. It goes from the end-user up to (TSOs)
although the core remains at the distribution system
operator (DSO) level [4]. The DSO level includes buildings,
communities of buildings, energy communities,
aggregators, energy s ervice companies (ESCO), locally
