Peer-to-peer energy systems for connected communities: A review of recent advances and emerging challenges

After a century of relative stability the electricity industry, extensive deployment distributed energy resources and recent advances in computation communication technologies have changed nature how we consume, trade, apply energy. The power system is facing transition from its traditional hierarchical structure to more deregulated model by introducing new distribution models such as peer-to-peer sharing for connected communities. proven effectiveness P2P benefiting both prosumers grid has been demonstrated many studies pilot projects. However, there still no implementation today's markets. This paper aims shed some light on this gap through comprehensive overview an insightful discussion challenges that need be addressed order establish viable management option market. To end, article, provide background different aspects sharing. Then, discuss systematic domain-based classification. We also review projects across globe. Finally, identify number scaling up market followed concluding remarks at end paper.
