The invention discloses a comprehensive
energy supply system and method for an urban complex and a large-scale public building group. A distributed
new energy power generation device is taken as a main
energy supply device, an
energy storage device is used for adjusting
instability of
new energy power generation, electric supply is taken as an auxiliary
energy source, compared with the traditionalenergy supply
system for the urban complex, dependence on the electric supply is reduced, the distributed
new energy power generation device generates
electricity by virtue of new
energy resources such as
solar energy and wind energy,
pollution is low, cost is low, distance with a load
demand side is short, transmission distance is short,
line loss is low, and geographic restriction is less; meanwhile, a
compressed air energy storage device is adopted, not only new energy resource
electric energy quality can be adjusted, but also multiple
energy supply demands such as power supply, cold supply and
heat supply can be met, and the technical problems that the current energy supply
system for the urban complex depends too much on municipal
electricity, the
line loss is high,
electricity utilization cost is high, reliability is low, energy supply type is single and the geographic restriction still exists even if terrestrial heat and a gas
turbine set are taken as supplements.
