Optimal scheduling of energy hubs in interconnected multi energy systems

Abstract

Because of society's full dependence on energy, one of the most significant challenges is to produce electricity and heat to meet demands. Integrating CHP (combined heat and power) and renewable resources is developing progressive advances due to the high green gas emissions from fossil fuels-based generators and the continuous growing energy demand. In this paper, energy hub model is presented as a strong solution for multi energy carriers (i.e., electricity and natural gas) for robust operation of the resources in smart distribution network. Energy hub operates different energy networks such as gas and electricity simultaneously. Energy hub enters gas and electricity as its inputs, including any contribution from the renewable energy sources. Energy hub function is supplying electricity and heat demands with minimum costs and green gas emissions. CHP presents the heart of energy hub to facilitate integration of electricity and natural gas networks. The proposed hub is scheduled by the aforementioned technologies during the different seasons of a year to minimize the costs and CO2 emissions.
