Improving economic and emission indices of two different CHHP structures by considering different management approaches

In this study, a combined hydrogen, heat and power (CHHP)-based microgrid (CHHP-MG) is investigated to provide thermal, hydrogen, and electricity loads in order to improve economic and environmental constraints. To increase efficiency of the proposed MG, two different structures are suggested and analyzed. Also, in order to increase economic profits and reduce pollution, management programs are applied to both generation and consumption sectors and their results are reviewed. Real time -based demand response (RTP-DR) is employed to the management side to improve consumptions pattern. The combination of sun flower optimization (SFO) algorithm and VIKOR technique is used to solve and select optimum solution among all obtained solutions. The results indicate the positive impact of the implemented management programs. However, by applying the program to the consumption side, the production side, and both sides, the microgrid's total pollution are reduced 23%, 41% and 43%This is while the microgrid operator's profit increases by 32.76%, 45.8%and 65%, respectively.
