The Danish Perspective of Energy Internet: From Service-oriented Flexibility Trading to Integrated Design, Planning and Operation of Multiple Cross-sectoral Energy Systems

Motivated by the success of internet technologies,energy internet,also referred as web-based smart grid(SG) or SG 2.0,is expected to offer innovative applications based on advanced connectivity and intelligent management of distributed energy resources(DER),systems and services with a strong focus on enabling a paradigm shift in the energy industry. Being the European leader in the development of SG technologies,Denmark has developed its unique understanding of the energy internet. Based on the learning from a number of research and development activities in Denmark,this paper introduced two important subjects of the energy internet from the Danish perspective,i.e.,service-oriented flexibility trading and integrated design,planning and operation of multiple cross-sectoral energy systems. Both elements are anticipated to bring in new business opportunities and challenges for different stakeholders in the energy industry; meanwhile these emerging solutions would both require and foster the transform of energy markets to facilitate the development of energy internet.
