Abstract

With  the  development  of  distributed  generation  (DG) technologies  and  the  implementation  of  policies  to  encourage  their applications,  The  Combined  Cooling,  Heating,  and  Power  (CCHP) systems is expected to play a greater role in the commercial buildings in  the  future.  CCHP  is  a  promising  efficiency  improvement  and  car-bon  mitigation  strategy,  but  careful  operation  mode  is  required  to achieve  a  reasonable  system  performance  according  to  energy  con-sumption   characteristics   of   buildings   and   technical   features   of equipments [1]. This paper presents  an  energy dispatch method which  minimizes  the cost of energy (e.g., cost of electricity from the grid and cost of natu-ral  gas  into  the  gas  turbine  and  boiler)  base  on  the  energy  hub  con-cept  and  by  regarding  carbon  market  rules.  The  system  includes combined  heating  power  (CHP)  module,  auxiliary  boiler,  absorption chiller, utility  grid and electrical, thermal,  and cooling  loads.  In  fact, by  solving  this  model,  optimal  energy  flow  will  be  determined  re-garding  both  the  amounts  of  electric,  thermal,  and  cooling  loads  in each time interval and prices of electricity and natural gas at the same time, by considering environmental constrains. In the cost function of this  model,  the  total  economic  benefit  of  this  system  is  maximized during total daily operation time. The  results  of  an  optimal  operation  model  have  been  discussed  eco-nomically and a case study has been investigated.
