  This manuscript aims to formalize and conclude the discussions initiated
during the PriTEM workshop 22-23 March 2023. We present important ideas and
discussion topics in the context of transactive energy systems. Moreover, the
conclusions from the discussions articulate potential aspects to be explored in
future studies on transactive energy management. Particularly, these
conclusions cover research topics in energy technology and energy informatics,
energy law, data law, energy market and socio-psychology that are relevant to
the seamless integration of renewable energy resources and the transactive
energy systems-in smart microgrids-focusing on distributed frameworks such as
peer-to-peer (P2P) energy trading. We clarify issues, identify barriers, and
suggest possible solutions to open questions in diversified topics, such as
block-chain interoperability, consumer privacy and data sharing, and
participation incentivization. Furthermore, we also elaborate challenges
associated with cross-disciplinary collaboration and coordination for
transactive energy systems, and enumerate the lessons learned from our work so
far.
