Problems solved by technology

Regarding the power characteristic modeling of CCHP units, in previous studies, it was assumed that CCHP operates at rated power, or that the conversion efficiency of CCHP is a fixed constant, but this assumption cannot accurately reflect the part load characteristics of CCHP. Scheduling results have a greater impact
[0010] Previous studies on microgrid optimal scheduling seldom involved ice storage air conditioners
