OPTIMIZING THE INTEGRATED ENERGY SYSTEM BASED ON ENERGY HUB MODEL

Abstract

Energy hubs play an important role in implementing the integrated energy system as an interconnection point between various energy components and networks. Multiple EHs can couple and form an interconnecting EHs system. This  paper  suggests  an  integrated  view  of multiple  energy  systems  with  renewable  in  energy  internet. Multi-period  optimal  energy  flow  in  electrical,  nature  gas and  district  heating  system  is  studied  with  the comprehensive  consideration  of  energy  consumption,  green gas  emissions  and  renewable  energy  output  based  on  the well-accepted  energy  hub  model.  Renewable  energy  is effectively  promoted  in  the  coordinated  operated  system. Compared  to  the  traditional  system  operation  method,  wind power  accommodation  is  realized  by  supporting  part  of  the heat loads in energy internet. A better comprehensive benefit can be achieved.
