Energy management systems aggregators: A literature survey

This paper focuses on the role of energy management systems aggregators, both concerning actual practice in industry as well as research, which can be seen as relevant players contributing to that endeavour. A review of recent literature and projects is made, putting in perspective the role of energy management systems aggregators in the Smart Grid context, in association with demand response programs and technologies, involving the participation of end-users in the provision of ancillary services. The aim is recognizing trends, opportunities, challenges and potential barriers regarding the creation of energy management systems aggregators to improve overall system performance, characterizing the services provided by aggregators and identifying potential research gaps.
