The invention discloses a comprehensive
energy system optimization operation method considering
electricity market transaction. According to the method, a
green certificate-carbon transaction interaction mechanism is comprehensively considered, P2G segmented operation is refined, and a heat-to-
electricity ratio adjustable technology is adopted, so that an optimized operation target with minimum energy
purchasing cost, carbon transaction cost,
green certificate transaction cost and energy abandoning cost is constructed, segmented
processing is performed on a traditional power-to-gas
system, green
hydrogen generated in the process is refined and utilized, and the energy
utilization rate of the
system is improved. Secondly, the heat-to-
power ratio adjustable technology of combined heat and power generation and
hydrogen fuel
cell equipment is researched, the
system flexibility is improved, and the energy abandoning cost is reduced; and finally, a
green certificate-carbon transaction interaction mechanism is introduced, a linkage relationship between carbon emission transaction and green
certificate transaction is established, and the
new energy consumption rate and the
renewable energy utilization rate are improved in a marketization form.
