تحلیل مالی و اندازه مطلوب و عمل برای یک سیستم انرژی چند حامل

In this paper, a model to find the optimal size and operation of CCHP, auxiliary boiler, heat and electrical storage unit for users is proposed by considering an integrated view of electricity and natural gas network using GAMS software. Then, as a case study, for a hotel in Tehran, this method is implemented. Finally, by applying COMFAR III software, useful financial parameters are calculated for the proposed multicarrier energy system with optimal elements.
